Meet students who spent their summer pursuing sustainability research

Through programs offered by the Stanford Doerr School of Sustainability, undergraduate students from Stanford and institutions across the U.S. worked on projects that tackled pressing environmental challenges and advanced fundamental knowledge about our planet. Here’s an inside look at their experiences.

This year, more than 70 undergraduate students engaged in summer research to develop new skills and deepen their understanding of Earth, climate, and society. Through five programs part of the Stanford Doerr School of Sustainability , undergraduates explored sustainability-related issues in disciplines ranging from energy and civil engineering to oceans and social sciences.

The five programs include Mentoring Undergraduates in Interdisciplinary Research (MUIR), organized by the Woods Institute for the Environment ; Summer Undergraduate Program on Energy Research (SUPER), organized by the Precourt Institute for Energy ; Sustainability, Engineering and Science - Undergraduate Research (SESUR); Hopkins Internships - Summer Undergraduate Research Funds (HI-SURF); and Sustainability Undergraduate Research in Geoscience and Engineering Program (SURGE).

The SURGE program is funded by the National Science Foundation and welcomes students from other U.S. institutions, especially those from underrepresented backgrounds doing research for the first time. The other programs receive funding from the Vice Provost for Undergraduate Education (VPUE).

Across all the programs, undergraduates contributed directly to research projects under the guidance of Stanford scholars. They also participated in shared group activities such as research seminars and graduate school workshops.

The large cohort allowed participants to learn from each other in addition to a variety of mentors. Building this community of support, in contrast with the sometimes isolating nature of individual research, was one of the main goals of bringing the five programs together last year.

Whether pursuing a scientific interest, trying out new tools, or discerning a potential career path, students used this summer to grow both academically and personally. Many hope to expand on the work they started, while others are moving forward with newfound clarity on their discipline. As they wrapped up their projects, three undergraduates shared insights about their research, personal growth, and how they made the most of the experience.

Evelyn Pung, ’27, SESUR participant

For Evelyn Pung, the motivation to research the link between environmental quality and human health was a personal one.

She grew up 10 minutes away from the ocean in Long Beach, California, but she rarely took trips to the beach. “The pollution at our beaches had gotten so bad, my parents didn’t want me to go, out of health concerns,” she said.

This summer through the SESUR program, Pung got involved in a project in the lab of civil and environmental engineering Professor Nick Ouellette . With her mentor, PhD student Sophie Bodek , she studied the movement of tiny plastic particles in bodies of water. Understanding how these pollutants travel through water in different environments can inform efforts to limit their spread.

Pung said that the freedom to actively control the experiment, combined with supportive mentorship from Bodek, made the research especially fulfilling.

“This whole experience has been a gratifying learning opportunity,” she said.

Trent La Sage, ’25, SURGE participant

Trent La Sage, an undergraduate student at the University of Florida, conducted research that brings together physics, Earth science, and materials science.

His project tackled a common problem in materials science: Insights about certain materials are not easily accessible to researchers. While findings about materials at ambient conditions can be uploaded to a public database for other scientists to reference, no such platform exists for materials at extreme conditions.

To address this, La Sage and other scholars worked on a program that uses computer vision and large language models like Chat GPT to pull data from published research papers, which can then be applied to work on future computational models.

The opportunity to collaborate on a large team was a highlight for La Sage, who appreciated the variety of viewpoints. He brought his own distinct perspectives to the group – both in discipline, as the only physics and astrophysics major, and in experience, having started his undergraduate education after several years in the workforce.

“It was very helpful to have people from other backgrounds. And we’ve been able to get a lot of things done that I wouldn’t have been able to get done myself,” he said.

Juan Martín Cevallos López, ’26, HI-SURF participant

After recurring moments of awe and discovery in his oceans-related classes at Stanford, Juan Martín Cevallos López, who prefers to be referenced by his first and middle name, discovered a passion for ocean science. He knew he wanted to get involved in research at the Stanford Doerr School of Sustainability’s Hopkins Marine Station in Pacific Grove and applied to the HI-SURF program.

Juan Martín contributed to three different projects – studying the impacts of ocean acidification on a particular species of seaweed, the development of bat star larvae in various temperatures, and the role of crustose coralline, a key component of coral reefs, in temperate environments such as Monterey Bay.

Throughout his research, Juan Martín was thrilled to be able to combine his knowledge of oceanography with other scholars’ expertise in marine biology and ecology, and he is eager to continue studying the ocean.

“I’m excited to see where it takes me, because it can literally take you anywhere,” he said.

Treatment Technology Demonstrations Using Practical and Affordable Manganese Treatment for Small Drinking Water Systems Grant

EPA awarded $1,000,000 in research grant funding to Cornwell Research Group to evaluate the effectiveness of common manganese treatment technologies in small drinking water systems. This research will improve the ability of states, Tribes and small utilities to adopt and implement common manganese treatment technologies. Manganese, an essential trace element in the human diet, is naturally occurring in the environment and prevalent throughout the United States in groundwater and surface water. However, recent evidence suggests that exposure to manganese at levels previously considered to be safe can cause cognitive and motor deficits in children. Small public water systems (serving 10,000 or fewer customers) frequently lack the resources and capacity to adopt and maintain manganese treatment systems.

The goal of this research is to inform states, Tribes, utilities, communities’ consultants, and state regulators on more effective manganese management in small, rural, and Tribal systems. This includes increased ability to implement manganese treatment technologies based on source water characteristics, capital, operations and maintenance costs, and maintenance requirements enabling more effective management of manganese removal in small systems.

As regions around the world invest billions in new infrastructure to overcome increasing water scarcity, better guidance is needed to facilitate cooperative planning and investment in institutionally complex and interconnected water supply systems. This work combines detailed water resource system ensemble modeling with multiobjective intelligent search to explore infrastructure investment partnership design in the context of ongoing canal rehabilitation and groundwater banking in California. Here we demonstrate that severe tradeoffs can emerge between conflicting goals related to water supply deliveries, partnership size, and the underlying financial risks associated with cooperative infrastructure investments. We show how hydroclimatic variability and institutional complexity can create significant uncertainty in realized water supply benefits and heterogeneity in partners’ financial risks that threaten infrastructure investment partnership viability. We demonstrate how multiobjective intelligent search can design partnerships with substantially higher water supply benefits and a fraction of the financial risk compared to status quo planning processes. This work has important implications globally for efforts to use cooperative infrastructure investments to enhance the climate resilience and financial stability of water supply systems.

Introduction.

Water scarcity impacts are increasingly frequent and severe in many parts of the world due to climate change, economic growth, and regulatory change 1 , 2 , 3 , 4 . Many regions are investing heavily in new infrastructure such as reservoirs, canals, and groundwater recharge facilities to bolster their water supply reliability and avoid negative impacts on public health, food security, power supply, and ecosystems 5 . In the U.S., federal and state funding for water systems has declined in recent decades, so that the large majority of water infrastructure spending comes from the local level 6 , 7 . Much of this funding comes from municipal bonds issued by local governments and water utilities, which provide up-front capital for projects in return for the principle plus interest to be repaid over many years. When investing in new infrastructure, water providers must be careful to balance the benefits of supply investments with their associated long-term debt obligations that must be repaid using water sales revenue 8 , 9 . This financial risk is especially important in light of concerns over the creditworthiness of drought-exposed water providers, concerns that can lead to higher borrowing rates and contribute to growing water affordability challenges in many regions 10 , 11 , 12 , 13 , 14 .

Collaborative partnerships, water supply regionalization, and consolidation have garnered attention for facilitating investment in large-scale infrastructure. Multiple water providers collaborating to finance, build, and operate shared facilities with joint benefits can be more cost-effective than independent provisioning due to economies of scale, reduced redundancy, improved access to capital, and diversification of supply and demand patterns 15 , 16 , 17 , 18 , 19 , 20 . Regions across the U.S., from California to Kentucky, have encouraged cooperative regional infrastructure investments with funding programs and technical assistance 21 , 22 .

However, collaborative infrastructure investments also carry risks. Modern water supply systems are governed by a complex set of hydrologic, infrastructural, and institutional drivers and uncertainties 23 , 24 , 25 . This presents a significant modeling challenge for water providers trying to estimate the expected benefits and costs of expensive infrastructure investments. For example, understanding the value of groundwater recharge facilities requires detailed modeling of short-timescale dynamics (e.g., atmospheric rivers or snowmelt-driven flood events), long-timescale trends (e.g., climate change and aquifer depletion), and time-evolving infrastructure constraints, water rights, and regulations 26 , 27 , 28 , 29 . Moreover, water supply systems in many regions are increasingly interconnected, which can lead to complex emergent behaviors within the coupled network because each water providers’ future supply reliability depends not only on its own actions and capabilities, but also on the actions and capabilities of other water providers in the network 30 , 31 , 32 . Shared water supply facilities that reduce system redundancy can also increase vulnerability during extreme conditions. Collaboration amplifies these challenges because it requires understanding not only the total aggregate benefits and costs of infrastructure investment, but also the uncertain distribution of these benefits and costs to individual partners over time 33 , 34 , 35 .

To date, little work has been done to help water providers understand the local-scale benefits and risks of investing in regional infrastructure partnerships. Water supply planning models are often highly aggregated, with many water providers grouped together, which limits their ability to discover local-scale tradeoffs for individual partners 23 , 33 . Moreover, little guidance exists to facilitate the design of resilient and equitable water supply infrastructure partnerships in institutionally complex systems. Existing economic planning frameworks for partnership design and cost apportionment are generally based on expected value benefit-cost analysis and/or game theoretic methods 36 , 37 , 38 , 39 , 40 . These methods are not well suited to realistic systems characterized by a large number of potential partners, interactive network effects, high uncertainty, and multiple conflicting objectives. In practice, infrastructure partnerships tend to emerge through pre-existing relationships or ad hoc arrangements. However, as we show in this study, this can lead to significant regret in complex water systems where partnership performance is challenging to predict.

In this work, we highlight the substantial water supply tradeoffs and financial risks that must be navigated by water providers when designing regional infrastructure partnerships. To do this, we develop an approach that uses detailed ensemble modeling of an interconnected water supply network under uncertainty, combined with a multiobjective intelligent search to discover the optimal tradeoffs in infrastructure partnership design (Supplementary Fig.  S1 ). We apply this approach in the context of ongoing canal expansion and groundwater bank development efforts in the San Joaquin Valley region of California, representative of the state’s efforts to encourage innovative partnerships through its Water Resilience Portfolio Initiative 21 . California is poised to spend billions of dollars on collaborative water infrastructure investments in the coming years 7 , 41 , 42 , 43 . We find a wide diversity of alternative infrastructure partnerships that exhibit strong tradeoffs between the size of a partnership and partner-level financial risk, and between water supply benefits for the investing partners and the rest of the region. Our findings also emphasize the importance of accounting for the substantial uncertainty in infrastructure performance that emerges due to California’s extreme hydroclimatic variability. Uncertainty in overall infrastructure performance is accompanied by high degrees of heterogeneity in the water supply benefits and financial risks experienced by individual water providers under different partnerships. Lastly, we demonstrate the advantages of our multiobjective intelligent search framework through a baseline comparison focused on the ongoing efforts to rehabilitate the Friant-Kern Canal. As an example, one of the candidate partnership designs discovered using our intelligent search procedure achieves 58% higher water supply gains while also significantly lowering the risk of extreme cost burdens for investing water providers when compared to the existing status quo canal expansion partnership. These insights are only attainable by moving beyond traditional ad hoc planning practices, expected value benefit-cost frameworks that do not resolve key differences in partners’ individual water supply and risk tradeoffs, and highly aggregated regional water supply models that fail to resolve the institutional complexities and local-scale dynamics that drive consequential differences in partners’ investment benefits and risks. Our results have important policy implications for California and broader insights for other regions working to develop collaborative investment partnerships to increase the resilience of their water supply systems.

Water supply infrastructure partnership design

The San Joaquin Valley region in California is home to over four million people and over five million acres of irrigated farmland 44 . The region’s long-standing water supply challenges have been amplified in recent years as climate change has made drought more frequent and severe, and as chronic groundwater overdraft has caused dry wells, widespread subsidence, water quality issues, and restrictive new regulations 21 , 44 , 45 , 46 . Local and state agencies are working to address these challenges by investing in new infrastructure and cooperative water management strategies 20 , 26 , 42 , 47 . In this study, we analyze two key ongoing infrastructure initiatives in the Tulare Lake Basin region of the San Joaquin Valley (Fig.  1 ). First, the Friant-Kern Canal is an important structure that primarily conveys San Joaquin River water south from Millerton Lake as part of the federal Central Valley Project. However, the capacity of the canal has been reduced by up to 60% due to subsidence-related damage 48 , 49 . In 2021, a collection of water providers known as the Friant Contractors decided to invest ~$50 million to rehabilitate the canal and expand its capacity, with various federal and state programs providing support for the rest of the estimated $500 million cost 50 . We consider only the $50 million borne by local users in this study. The fact that we find significant financial risks even with this unusually favorable cost structure serves as a warning for other less-subsidized infrastructure investments in the region. We also consider a second infrastructure investment in a new groundwater bank, which would route surplus water available in wet periods into infiltration basins to replenish the aquifer and allow for additional groundwater pumping during dry periods 20 , 27 , 28 , 42 . We estimate this project would also cost local water providers $50 million based on cost estimates for other groundwater storage projects being developed throughout the region 43 .

The infrastructure projects considered in this study are an expansion of the Friant-Kern Canal (FKC, dotted red line) and a new groundwater bank near the FKC and the Tule River (red star). “Friant Contractors” are water providers with contracts to receive Central Valley Project water from the FKC. “Non-Friant Contractors” are other water providers in the region without Friant contracts. The bottom center inset shows KCWA Improvement District No. 4, a water provider that overlaps with other providers in the square-designated region of the main map.

Using the cooperative infrastructure investment context of the Friant-Kern canal rehabilitation and its potential augmentation with a new groundwater bank, we simulate the performance of alternative infrastructure partnerships using the California Food-Energy-Water System (CALFEWS), a highly detailed water resource systems model that simulates daily reservoir operations, environmental flow rules, water rights, interbasin transfer projects, and conjunctive surface and groundwater supply management at the level of individual water providers 23 , 33 . The high-fidelity system representation of the model allows us to generate new insights into infrastructure partnership design compared to existing lower-fidelity water supply planning models that cannot resolve the multi-timescale dynamics of managed aquifer recharge or the multi-spatial scale distribution of water supply benefits and financial risks for individual water providers 23 , 33 . Each partnership is evaluated across an ensemble of daily time step 30-year hydrologic sequences from a synthetic streamflow generator that captures the spatial correlation across the state as well as the interannual persistence of wet and dry periods (see Methods and Supplemental Note  S1 ). This allows us to explore the impact of California’s severe internal hydroclimatic variability on the water supply benefits and financial risks resulting from these infrastructure investments 51 , 52 . The synthetic streamflows used in this study serve two major technical benefits: (1) they permit a well-founded statistical representation of the plausible flood-drought regimes that regional infrastructure investments could potentially face in the near term, and (2) they are intentionally strongly optimistic in neglecting longer-term climate changes to show that even without climate change effects, there are immense uncertainties that challenge our understanding of investment partnerships’ water supply and financial risk tradeoffs. Finally, for an additional check on partnership robustness, we compare the performance of two example partnerships under 20 alternative streamflow scenarios for 2021–2050 from an existing dataset generated using a multi-model ensemble of downscaled climate model runs for California from the Climate Model Intercomparison Project Phase 5 (CMIP5) and the Variable Infiltration Capacity (VIC) model (See Supplementary Note  S1 for details) 53 , 54 , 55 , 56 .

Partnership performance is assessed over the 30-year simulation (a common municipal bond payback period 57 ) according to four decision-relevant metrics related to partnership size, water supply benefits, and financial risk. We combine this ensemble modeling framework with a multiobjective intelligent search framework that leverages the Borg MultiObjective Evolutionary Algorithm (MOEA) 58 , 59 to test ~300,000 candidate infrastructure investment partnerships to discover the best-performing partnerships that represent the optimal tradeoffs across the four metrics (Supplementary Fig.  S1 ). The elements of partnership design that are optimized can be described with three questions: (1) In which project does the partnership invest (canal expansion, groundwater bank, or both)? (2) Which subset of 40 water providers in the region should participate? (3) What “ownership share” should be assigned to each partner, governing its capacity in the project and its share of annual debt payment obligations? Additional details on our partnership design and evaluation framework can be found in Methods and Supplementary Notes   S2 and 3 .

Understanding diverse partnership design options

Our multiobjective intelligent search process yields a set of 270 unique partnership structures which are highly diverse in terms of their design (i.e., different combinations of partner districts and their levels of relative investment) as well as their performance across different objectives—this broad suite of alternatives collectively represents a wealth of information which would not have been available using traditional ad hoc partnership planning processes which typically consider only a small number of candidate arrangements. Each candidate partnership within the set of 270 approximately Pareto-optimal partnerships (hereafter referred to as “optimal tradeoff partnerships”)represents a different balance of compromises across the four conflicting objectives.

The majority of optimal tradeoff partnerships (83%) are found to invest in both canal expansion and groundwater banking (Fig.  2a ). This suggests a synergistic relationship. The surface water gains from the Friant-Kern canal expansion generally occur during relatively high-flow periods, when available water supply exceeds immediate demand, so it is complementary to pair the expansion with additional storage 29 , 60 . The remaining 17% of optimal tradeoff partnerships invest only in canal expansion, with no partnerships investing in groundwater banking alone. This highlights the importance of considering the interactive effects across alternative infrastructure projects and the potential for synergistic gains when bundling regional investments together.

There is a high degree of diversity in the way that partnerships can be designed. The optimal tradeoff partnerships range in size from 11 to 24 water providers, with 16–19 being the most common partnership sizes (Fig.  2a ). The fact that no optimal tradeoff partnership contains fewer than 11 partners supports the vision of California’s Water Resilience Portfolio Initiative, which touts the benefits of collaboration for efficiently meeting the state’s water supply goals 21 . Larger partnerships are expected to have larger and more diverse sources of water supply, water demand, and local infrastructure and, thus, are more capable of fully utilizing the new shared infrastructure throughout the year and across a range of conditions.

There is also diversity in the concentration of ownership across the partnerships. There are no partnerships that distribute ownership equally (e.g., 20 partners with a 5% share each). Instead, most partnerships have a few partners with disproportionately large ownership shares and a larger number of partners with rather small shares, with the magnitude of these differences varying across the optimal tradeoff set (Fig.  2b ).

Considering the geographic context of these partnerships (Fig.  2c–e ), we find that certain providers almost always participate and generally carry large ownership shares (dark gray), while others rarely participate and tend to take rather small shares (yellow/light green/light brown). There are also providers that regularly participate with small shares (medium brown) or that irregularly participate with large shares (teal). The set of providers that participate in over half of the optimal tradeoff partnerships and that have a median ownership share above 4% (top right quadrant of Fig.  2e ) are heavily concentrated in the central region along the Friant-Kern Canal in the vicinity of the Tule River (Figs.  1 and 2c ). These are the providers most heavily impacted by the heavy subsidence in this area and the subsequent restriction in canal conveyance capacity. Many of these providers are Friant Contractors, but there are also several Friant Contractors that participate infrequently and/or with small shares, as well as several non-Friant districts that can play an important role in investment partnerships, as we will see in subsequent sections.

These results demonstrate the complexity of partnership design and the range of roles that different water providers can play in partnership creation given their unique contexts: the local infrastructure networks, water rights, hydrologic context, and other factors that impact their ability to procure and store additional surface water as a result of the collaborative investment. Moreover, many providers can span a range of ownership shares across the optimal tradeoff set depending on how the rest of the partnership is constructed (Fig.  2d ). This results from a large number of provider interactions across the coupled statewide-to-local-scale infrastructure network (e.g., shared canal space) as well as interactions in the institutional space (e.g., water contracts and groundwater banking arrangements). These interactions can lead to path-dependent system dynamics across the region, where each providers’ water supply operations can impact the availability of water and infrastructure capacity for the other providers in the network. This highlights the importance of capturing local-scale dynamics and network interactions between water providers when designing collaborative infrastructure investments 23 , 33 .

Key performance tradeoffs for water supply investment partnerships

We find that water providers face severe tradeoffs across four decision-relevant metrics when designing collaborative infrastructure investments (Fig.  3 ). The optimal tradeoff partnerships can increase average surface water deliveries to partners by anywhere from 48 to 85 GL/year. For context, 85 GL (69 kAF) is equivalent to 13% of Millerton Lake’s capacity, or 3.4% of the average annual groundwater overdraft for the entire San Joaquin Valley 44 . This represents a meaningful increase in surface water deliveries at the local scale, which could help partners reduce their over-reliance on groundwater pumping in order to meet their obligations under the Sustainable Groundwater Management Act, although this would need to be only one piece in a larger portfolio of water supply resiliency investments to address the scale of the challenge of groundwater overdraft in the Valley 42 .

Each colored line represents one of the 374 optimal tradeoff partnerships. The location where a partnership intersects each vertical axis represents its performance with respect to that objective. Each objective is oriented such that the preferred direction is up (e.g., maximum water gain, minimum cost). Thus, ideal performance would be a horizontal line across the top, while diagonal segments represent tradeoffs between conflicting objectives.

In addition to water supply volumes, we also calculate the worst-off partner cost of gains, defined as the annual debt service payment divided by the annual captured water gain for the worst-off partner in each partnership. The 90th percentile cost of gains across alternative hydrologic scenarios, which we use as a proxy for partner-level financial risk, ranges from $162/ML to over $1000/ML in different partnerships (Fig.  3 ; see Methods for the detailed definition). For context, water providers in this region generally charge $32-154/ML ($40–190/AF) for irrigation water 61 , which is used to pay for debt service on infrastructure investments, as well as the cost of procuring water and other operating expenses. Financial distress can occur when a water provider agrees to future debt obligations as part of an infrastructure partnership but does not end up receiving substantial water supply benefits from the project. Optimal tradeoff partnerships with very high costs of gains may be unable to raise customer rates high enough to pay off the debt associated with the new infrastructure. This could lead to default, credit downgrade, deferred maintenance, or other challenges 9 , 10 , 11 . Significant increases in customer water rates are also problematic due to the water affordability and water quality challenges in many low-income communities, as well as the thin profit margins in many agricultural regions where higher rates for irrigation water can make farming infeasible 12 , 14 , 44 , 62 , 63 .

One strong tradeoff that emerges from these results is that the largest partnerships tend to produce the largest financial risks for their worst-off partners. For example, over half of partnerships with 24+ partners have at least one partner paying over $1000/ML, while each partnership in which all partners pay under $200/ML has 16 or fewer partners (Supplementary Figs.  S2 and S3 ). It is intuitive that beyond a certain point, a larger number of partners can make it harder to satisfy all partners’ needs. Yet this finding also points to an important tension in California’s recent efforts to incentivize large-scale collaborative water supply investments 21 . Large-scale collaboration in infrastructure investment can indeed be beneficial up to a point, as evidenced by the fact that all optimal tradeoff partnerships have 11+ partners (Fig.  3 ). However, it is also critical to understand the limits of large-scale collaboration and the significant financial risks that can arise from these arrangements, in order to ensure that all partners are receiving adequate benefits to justify their debt. There are also likely additional tradeoffs beyond those quantified in our work, such as costs, delays, and other challenges related to coordinating and contracting across a large and diverse set of partners with their own incentives and historical relationships 16 .

We also find a strong tradeoff between water supply benefits for the partners vs. other non-partner water providers in the region (Fig.  3 ). New infrastructure projects alter water providers’ path-dependent supply and demand behaviors, with ripple effects throughout the broader interconnected water supply network. This can lead to indirect effects on water availability for other water providers in the region that are not party to the investment. We find that the non-partner impacts vary greatly across the optimal tradeoff set, from gains of 31 GL/year to losses of 10 GL/year on average. In general, the partnerships with the largest captured water gains for the partners tend to significantly reduce deliveries to non-partners (Supplementary Fig.  S4 ). This suggests that these infrastructure partnerships benefit not only from newly captured “surplus” water that would have otherwise flowed out of the region but also from reallocated water that would have otherwise been delivered to their neighbors.

This raises important questions about the extent to which non-participating water providers have the ability to block infrastructure investments that could negatively impact them. Water providers investing in new infrastructure in California must navigate the state’s complex web of different water rights, environmental laws, and administrative procedures 25 , 26 . In particular, as in other western states, many changes related to water rights and diversion and storage patterns require that the change will cause “no injury” to other water rights holders 64 . Third parties can object if they believe any injury has occurred, and outcomes are adjudicated in court or with the State Water Resources Control Board on a case-by-case basis based on the unique hydrologic and legal context. Paying for hydrologic modeling studies and legal analysis to support the validity of any changes to water diversion or storage patterns, as well as potentially compensating any injured parties, can add significant expense and delays to the approval process 65 . For example, previous studies have found that transaction costs related to hydrologic modeling and legal support required for approval of water rights transfers in California and Colorado can increase the total cost of the transfer by 100% or more 66 , 67 . In California, the diversity of legal regimes and water laws in the state (e.g., prior appropriative rights vs. riparian rights vs. federal/state water supply contracts) further complicates the evaluation of third-party injury related to alternative water supply options. More guidance is needed from the state to streamline procedures and facilitate more collaborative partnerships. When we exclude partnership designs from our optimal tradeoff set, which are expected to reduce total average water deliveries to non-partners to account for potential political and legal constraints, the best achievable captured water gains for partners are reduced by 6% (Supplementary Fig.  S5 ). Excluding partnerships that would cause injury to individual providers (rather than in aggregate) or in individual years or hydrologic scenarios (instead of expected value across many scenarios/years) would be expected to substantially reduce the set of feasible partnerships further. This negative interaction represents a major challenge for supply reliability and groundwater sustainability efforts and points to the need for more coordinated regional infrastructure planning efforts to develop synergistic water supply portfolios with regional benefits and minimal third-party injuries, as well as programs to mitigate and compensate for these injuries.

It is perhaps surprising that such a wide diversity of performance tradeoffs is possible, given that each of these 270 optimal tradeoff partnerships invests in the exact same canal expansion project, sometimes bundled with a groundwater bank (Fig.  2a ). This demonstrates the critical and underappreciated role of partnership design itself in governing the performance of collaborative infrastructure investments. The variety of partnership designs associated with different performance tradeoffs means that it is not possible to establish a single “best” partnership a priori without first establishing decision-making preferences (i.e., how much to weigh partnership size vs. captured water gains vs. regional non-partner impacts vs. worst-off partner cost). Moreover, the striking performance tradeoffs that emerge from nuanced changes in partner selection and ownership distribution highlight the significant advantages of pairing detailed water supply models like CALFEWS 23 (capable of resolving daily-timescale coupled hydrologic, infrastructural, and institutional dynamics at the scale of individual water providers) with multiobjective intelligent search algorithms like the Borg MOEA (capable of exploring a much wider range of candidate partnership designs compared to traditional ad hoc planning processes).

Navigating uncertainty and heterogeneity in tradeoffs

We also find that uncertainty from hydroclimatic variability can have significant impacts on water supply and financial risk consequences for infrastructure investments, and thus uncertainty should be systematically analyzed in partnership design. When an investment partnership borrows money in municipal bond markets to pay for a new infrastructure project, it is subject to significant uncertainty related to the future realized water supply benefits and sales revenues. This uncertainty can be highly decision-relevant when there is a wide range of performance values across plausible alternative future scenarios. The metrics in Fig.  3 represent aggregate performance computed across an ensemble of 79 sampled 30-year sequences of multi-site correlated daily streamflows. This ensemble captures a wide but plausible range of hydrologic conditions that investments could confront over a 30-year bond payback period (see Methods and Supplementary Notes   S1 , S2 ). The captured water gain metric in Fig.  3 is calculated as the mean values across the 79 sampled 30-year daily streamflow sequences, while the worst-partner cost of gains metric is calculated using the 90th percentile across scenarios. However, a deeper examination of performance in individual sampled 30-year daily hydrologic sequences reveals significant levels of uncertainty in the benefits that water providers can expect due to internal hydroclimatic variability. These uncertainties can be highly meaningful in the context of risky large-scale infrastructure investments.

We now highlight a “Compromise Partnership” selected as an example for navigating the tradeoffs in the optimal partnership set. The Compromise Partnership has 16 partners investing in both canal expansion and groundwater banking (Fig.  4a ) and is selected for its relatively high performance across all four performance objectives (see Methods). Like all partnerships in the optimal tradeoff set, the Compromise Partnership is subject to significant performance uncertainty (Fig.  4b ). Although the expected value of captured water gain is 76 GL/year, the captured water gain in individual 30-year daily hydrologic sequences can range from 43 to 109 GL/year, or 57% to 143% of the expected value. The captured water gain for non-partners is even more variable. Although the partnership leads to a minor reduction in non-partner deliveries to on average (0.5 GL/year), the impact in individual hydrologic scenarios spans a wide range, from a reduction of 81 GL/year to a gain of 26 ML/year. The worst-partner cost of gains also spans a wide range, from $105/ML in the best scenario (58% of the 90 th percentile metric of $180/ML) to $407/ML in the worst scenario (227% of the 90th percentile metric). This cost differential could easily be the difference between a project that affordably improves surface water access and one that provides little water supply benefit and overburdens water providers with debt and their customers with rate increases.

The green line represents the aggregated performance of the Compromise Partnership, while the green shaded areas show the probability distribution of single-scenario performances for the Compromise Partnership. c Heterogeneity of partner-level performance for the Compromise Partnership. Each shaded area labeled 1–16 represents the distribution of costs of gains for a different water provider partner across the 79 sampled 30-year daily hydrologic sequences. The partners are sorted and colored by ownership share. The distributions labeled “All” represent the partnership-level aggregated costs (black) and the costs for the worst-off partner across alternative scenarios.

The benefits and risks of different partnerships can be very unevenly distributed across the project partners due to the complexity of the interconnected water supply system dynamics and the heterogeneity of local contexts for water providers. The partners within the Compromise Partnership experience a range of expected costs of gains for their water supply benefits (Fig.  4c ), which is common across the optimal tradeoff partnerships. The heterogeneity of expected costs stems from the similarly heterogeneous expected captured water gains at the partner level (Supplementary Fig.  S8a ). The latter is not inherently problematic so long as each partner’s captured water gain is appropriately matched to its ownership share in the project and, thus, its share of the annual debt payments. For example, if Provider A receives twice as much captured water gain as Provider B, but also makes annual debt payments that are twice as large, then the two providers are effectively paying the same unit cost for their captured water gains. However, we find the ownership shares to be imperfectly matched in this and other partnerships, so that some providers pay more than their “fair share” on average, and others pay less (Fig.  4c ).

Moreover, partners can experience widely varying degrees of uncertainty related to their individual performance tradeoffs (Supplementary Fig.  S8 ). The aggregate cost of gains for the Compromise Partnership (Fig.  4c , black distribution) has a relatively low chance of exceeding $100/ML in any of the sampled hydrologic scenarios. However, the cost of gains for the worst-off partner (red distribution) has a much wider range, reaching over $400/ML in the most challenging scenario. This risk is not evenly distributed, with some partners experiencing a disproportionate share of extreme costs (e.g., three out of sixteen partners experiencing worst-case costs over $300/ML) and others experiencing uniformly low costs across the sampled hydrologic scenarios (e.g., four partners experiencing worst-case costs under $100/ML). This is critical because the heterogeneity of water supply benefits and financial risks could threaten the cooperative stability of the partnership itself if partners do not perceive the investment to be sufficiently fair and locally beneficial 30 , 33 .

As noted before, these results (Fig.  4 ) are a strongly optimistic portrayal of partnership performance under conditions of uncertainty and heterogeneity, which reinforces the importance of our results given the impacts of anthropogenic climate change. Climate change is expected to make dry conditions increasingly frequent and severe in California and many other regions 2 , 68 , 69 . Our expressly optimistic framing of future hydroclimatic conditions in California neglects any nonstationary effects from anthropogenic warming or low-frequency decadal climate oscillations. However, even under such optimistic conditions, the extreme levels of hydroclimatic internal variability experienced in California 51 , 52 lead to significant decision-relevant uncertainty in cooperative infrastructure investment outcomes over the next several decades. Water providers, therefore, must find a way to improve surface water reliability and reduce groundwater overdrafts without exacerbating the growing water affordability concerns for agricultural and urban water users 12 , 13 , 14 . We caution that decision-makers should carefully consider the impacts of uncertainty and financial risk before committing to significant debt associated with new infrastructure partnerships. However, this will require updated planning frameworks that move beyond expected value-based benefit-cost analyses (e.g., exploratory modeling and robust decision-making approaches 70 , 71 , 72 , 73 , 74 ), as well as detailed water supply models that can account for complex local-to-regional scale dynamics in coupled hydrologic, infrastructural, and institutional systems under diverse conditions 23 . Flexible planning frameworks such as Engineering Options Analysis, Dynamic Adaptive Policy Pathways, and adaptive contract structures can also help decision-makers to design for flexibility and delay expensive irreversible investment decisions until they have gathered more information about likely future conditions 75 , 76 , 77 , 78 , 79 .

Regret of the current baseline partnership design

Lastly, we highlight the potential to meaningfully improve existing ad hoc water supply infrastructure planning processes by demonstrating the significant regret associated with the current baseline planned Friant-Kern Canal rehabilitation partnership, which yields substantially lower water gains and much higher financial risk for some partner districts compared to the Compromise Partnership. In practice, infrastructure partnerships are generally established via pre-existing relationships or ad hoc processes. Most infrastructure investments are then evaluated using low-resolution models that fail to capture key system features (i.e., interdependent flood-drought dynamics, institutional constraints, infrastructure operations, etc.), and the preferred alternative is selected based on highly aggregated traditional expected benefit-cost analyses. These processes fail to grapple with the complex tradeoffs, uncertainties, and heterogeneities in modern interconnected water supply systems and, therefore, are ill-equipped to design robust and equitable infrastructure partnerships. To elucidate the regret associated with current baseline planning processes, we analyze the ongoing rehabilitation of the Friant-Kern Canal by the Friant Contractors, a collection of water providers with contracts to receive Central Valley Project water from Millerton Lake via the Friant-Kern Canal (Fig.  1 ) 48 , 49 , 50 . We model a “Status Quo Partnership” (Fig.  5a ) after this real-world example, as opposed to the partnerships in the optimal tradeoff set, which are designed via our multiobjective intelligent search process (see Methods).

a Map showing the Friant Contractor water providers participating in the Status Quo Partnership, which invests only in canal expansion. Partners are colored by their ownership share in the partnership, while non-partners are colored white. b Parallel coordinate plot showing partnership performance across four conflicting objectives. Each gray line represents the performance of a different optimal tradeoff partnership, aggregated across the 64 sampled 30-year daily hydrologic sequences. The green line represents the aggregated performance of the Compromise Partnership, while the green shaded areas show the probability distribution of single-scenario performances for the Compromise Partnership. Similarly, the orange line and orange shaded areas represent the aggregated and disaggregated performance for the Status Quo Partnership. c Heterogeneity of partner-level performance for the Status Quo Partnership. Each shaded area labeled 1–16 represents the distribution of costs of gains across the 64 scenarios for a different water provider partner. The partners are sorted and colored by ownership share. The distributions labeled “All” represent the partnership-level aggregated costs (black) and the costs for the worst-off partner across alternative scenarios.

Although it does provide significant benefits to its 16 partners, the Status Quo Partnership is matched or outperformed on all four aggregate performance metrics by the Compromise Partnership (Fig.  5b ). The Status Quo Partnership produces 37% lower captured water gains on average, and when accounting for the uncertainty it is outperformed in the large majority of hydrologic scenarios. The Status Quo Partnership also produces slightly larger negative impacts on non-partners in the region on average (0.9 vs. 0.5 ML/year), although the Compromise partnership produces larger negative impacts in its most extreme hydrologic scenarios.

The Status Quo Partnership also carries significantly greater financial risk. The worst-partner cost of gains exceeds $1000/ML in all 79 sampled hydrologic scenarios. Two water providers in particular (Partners 8 and 14) receive marginal or even negative captured water gains, and thus experience costs over $1000/ML, in a large majority of scenarios (Fig.  5c , Supplementary Fig.  S9 ). Five other providers also exceed $1000/ML in a smaller set of scenarios. In contrast, there are no sampled hydrologic scenarios where any of the 17 water providers in the Compromise Partnership experience costs of gains above $407/ML, and in 90% of scenarios, the worst-off partner pays less than $180/ML.

We also further test the robustness of the Compromise and Status Quo Partnerships using an ensemble of 20 downscaled CMIP5 climate models over the 2021–2050 period. Interestingly, both partnerships show relatively similar expected performance and levels of uncertainty for the CMIP5 ensemble compared to the original ensemble of synthetically generated scenarios (Supplementary Figs.  S10 and S11 ). In fact, each partnership shows slightly improved captured water gains in the CMIP5 scenarios, as well as somewhat lower partner-level financial risks on the whole. However, the difference across ensembles for each partnership (Supplementary Figs.  S10 and S11 ) is found to be much smaller than the differences between the two partnerships (Fig.  5 ), suggesting that the choice of ensemble in this case is unlikely to change the decision makers’ preferences about which partnership is preferrable.

Three major differences in partnership design contribute to the Compromise Partnership’s dominance over the Status Quo Partnership. First, it couples the canal expansion project with new groundwater banking facilities, which help to capture more surplus water during high-flow periods when all partners’ immediate demands are already satiated. A majority (83%) of partnerships in the optimal tradeoff set invest in both projects (Fig.  2a ), suggesting that the performance gains from the synergistic pairing are generally worth the higher price tag. Second, although the Compromise Partnership and the Status Quo Partnership have significant overlap in participating providers (Figs.  4 a and 5a ), the Compromise Partnership discovered through multiobjective intelligent search removes several Friant Contractors with marginal benefits and significant financial risks. It also adds several other non-Friant providers that stand to benefit from the infrastructure investment. Widening the net beyond the Friant Contractors allows for a more diversified portfolio of water supplies and demands and increases the utilization of the infrastructure across a range of seasons and conditions. Lastly, the ownership shares and annual debt payments as refined through the multiobjective intelligent search process are better matched to partner-level captured water gains in the Compromise Partnership than the Status Quo Partnership, which helps to equalize the cost of gains across partners. These results highlight the significant regret associated with traditional ad hoc partnership design processes and the substantial improvements that can be achieved by combining detailed ensemble water supply modeling with multiobjective intelligent search.

According to the American Society of Civil Engineers, the U.S. will need to invest $109 billion per year in water infrastructure over the next 20 years to overcome the current investment gap in light of the deteriorating condition of the existing infrastructure stock as well as factors related to climate change, economic change, and regulatory change 5 . Collaborative partnerships and regionalization can be effective tools for facilitating investment by lowering costs and increasing flexibility. However, collaboration also brings new challenges related to the design and evaluation of robust infrastructure investments in institutionally complex water supply networks. Addressing these challenges will be critical to achieving California’s water supply resilience and groundwater sustainability goals 21 , 42 . More broadly, these insights should be highly relevant to many other regions around the world that are working to adapt to increasing water scarcity, especially in regions with complex water institutions and interconnected infrastructure systems.

Our results have several key implications for water providers seeking to meet their supply reliability and groundwater sustainability goals through collaborative investment. First, water providers and planning agencies should assess financial risk as a key metric for infrastructure partnership design, along with more traditional planning metrics such as water supply reliability. Second, although the success of large partnerships (11–26 partners) in our analysis supports a collaborative vision for infrastructure planning, our results also highlight an important tension between partnership size and partner-level financial risk that must be navigated by water providers and planning agencies. Third, given the strong tradeoff between water supply benefits for partners vs. non-partners, there is a need for state and national planning agencies to provide more guidance on the role of external stakeholders in the planning process when infrastructure investments have the potential for negative external impacts. Fourth, the high level of variability across alternative sampled hydrologic scenarios demonstrates the importance of considering internal hydroclimatic variability in infrastructure partnership evaluation, while the significant partner-level heterogeneities highlight the critical role of highly detailed water supply models that can resolve complex infrastructural and institutional constraints and multiscale system dynamics. Both uncertainty and heterogeneity provide highly decision-relevant information that would not be available using traditional aggregated mean benefit-cost analyses. Fifth, given the preponderance of partnerships investing in both canal expansion and groundwater banking within the optimal tradeoff set, there is clearly a need for more integrated planning efforts that consider the interactive effects of multiple simultaneous infrastructure investments spanning local-to-regional scales within the larger water supply network. Finally, the severe performance tradeoffs that emerge from relatively subtle changes in partnership design across the optimal tradeoff set and the dominance of the Compromise Partnership over the Status Quo Partnership both demonstrate the value of multiobjective intelligent search for improving the design of infrastructure partnerships in institutionally complex water supply networks relative to traditional ad hoc planning processes.

In this study, we explore hydrologic uncertainty using a broad ensemble sampling of plausible 30-year daily streamflow sequences from a synthetic generator trained on historical observations. This represents an actively optimistic framing because we only account for stationary hydroclimatic variability while neglecting nonstationary climate change. Despite the optimistic framing, we nevertheless find that uncertainties in assessing water supply benefits and financial risks are highly consequential as a result of California’s highly variable climate. We also find that our synthetically sampled streamflow scenarios span a similarly wide range of extremes as a multi-model downscaled CMIP5 ensemble for the 2021–2050 period, and that simulated partnership performance across the two ensembles is similar. Future work will consider the impact of a wider range of plausible nonstationary climate futures to account for the impact of climate change on uncertainty and decision-making. Additionally, it will consider other uncertainties related to future water demand, reservoir operations, infrastructure performance, and cost. These factors are expected to further widen the envelope of uncertainty around aggregate and partner-level impacts and exacerbate the challenge of designing robust partnerships.

Our results highlight the significant regret associated with traditional ad hoc partnership planning processes and the substantial improvements that can be achieved by combining detailed ensemble water supply modeling with multiobjective intelligent search. However, in practice, partnerships emerge as part of a complex human process within a broader historical and institutional context. Future work should investigate how these computational tools can best be integrated with more traditional stakeholder-based collaborative planning efforts in order to discover new alternatives, illuminate tradeoffs, and improve transparency to break down historical silos 80 , 81 , 82 , 83 . Local planners and operators have important knowledge about infrastructural and institutional behaviors, as well as legal, fiscal, and personal constraints, that may not be presently captured in our modeling framework. Thus, in practice it would be critical to complement the multiobjective intelligent search with iterative processes of evaluation and human feedback to better capture this explicit and implicit knowledge. It is also important to note that different water providers will have different abilities to pay for infrastructure, unique vulnerabilities to financial risk based on their underlying customer bases, and different levels of political power. Although we focus on equality between partners for this study, future work should extend this analysis by considering equity and asymmetries in economic and political power, customer vulnerability, racial injustice, and historical responsibility for groundwater overdraft 62 , 84 , 85 , 86 , 87 . The concepts of equity and resilience have many possible definitions, and more work is needed to understand how differing qualitative and quantitative understandings of these concepts are impacted by model representational fidelity and multiobjective formulations to shape perceptions of infrastructure performance and tradeoffs 88 , 89 , 90 , 91 .

Future extensions of this work should also consider the role of contractual innovations, environmental impact bonds, engineering options analysis, and adaptive risk management strategies in redistributing and reducing the partner-level financial risks associated with cooperative infrastructure investments 34 , 77 , 92 , 93 , 94 . Lastly, we acknowledge that the complexity and computational requirements of our multiobjective intelligent search workflow may initially present a challenge for water providers looking to adapt this analysis for new contexts. This will also require breaking down silos across engineering, planning, and policy experts. University researchers, cooperative extension services, and federal/state planning agencies should invest resources towards developing significant capacities for facilitation, training, and technology transfer to enable the efficient application of cutting-edge computational tools to critical public planning challenges. The proliferation of free and open-source software and the declining costs of computing resources should also continue to reduce the barriers to this type of analysis over time.

Candidate infrastructure investments

Following Hamilton et al. 33 , we consider two candidate infrastructure projects in this study. First is the rehabilitation of the Friant-Kern Canal. The canal has been severely damaged by subsidence related to groundwater overdraft, which has reduced its conveyance capacity by up to 60% in some regions 48 , 49 . A collection of water providers known as the Friant Contractors (Fig.  1 ) is currently investing roughly $50 million in rehabilitating the canal, with the remainder of the $500 million cost to be covered by various federal, state, and regional organizations 50 . For this study, we consider only the $50 million cost share allocated to the local water providers. We assume for simplicity that the modeled investment will restore the entire length of the canal to its original conveyance capacity.

The second candidate infrastructure project is a new groundwater banking facility near the confluence of the Friant-Kern Canal and the Tule River. This hypothetical project is not based on any particular existing or planned groundwater bank but is largely consistent with other recent and planned investments in the region 42 . We estimate that the bank’s cost to project partners will be $50 million, which is on par with other recent and planned investments in groundwater recharge facilities 43 . There are three major parameters governing the capacity of groundwater recharge facilities in our water resource simulation model: the infiltration pond storage volume, the dry soil infiltration capacity, and the recovery pumping capacity. These are set to 0.74 GL/day (0.6 kAF/day), 0.37 GL (0.3 kAF), and 0.25 GL/day (0.2 kAF/day), ~25% of the parameter values for the largest groundwater bank in the region, the Kern Water Bank 95 .

Both infrastructure projects are assumed to be financed using 30-year revenue bonds with 3% interest, broadly consistent with revenue bonds issued in 2019 by water districts in California 57 . Assuming equal annual payments over time, this translates to a debt payment of $2.55 million/year for partnerships investing in either canal expansion or groundwater banking, or $5.1 million/year for partnerships investing in both projects. All other infrastructure investment details are taken to be consistent with Hamilton et al. 33 .

The elements of partnership design to be optimized can be understood as answering three questions. First, which infrastructure project should be built: canal expansion, groundwater banking, or both? Second, out of 40 candidate water providers in the region (Fig.  1 ), which subset should work together as partners? Third, once the set of partners has been established, how should the “ownership shares” be distributed amongst them? Each partner’s ownership share dictates its share of priority capacity in the new infrastructure as well as its share of annual debt payment obligations, following Hamilton et al. 33 . Importantly, the annual debt payment cost considered here does not include any operating or maintenance costs associated with the infrastructure or the cost of procuring additional water. It thus represents an incomplete and optimistic view of the potential for financial risk associated with these infrastructure partnerships. The minimum allowable ownership share is set to 1%, so that each partner’s share is between 1 and 100%. All of the partner ownership shares must sum to 100%.

Infrastructure partnership evaluation

This study employs the California Food-Energy-Water System (CALFEWS), a free, open-source, Python/Cython-based simulation model of California’s water resource system dynamics with a particular focus on the San Joaquin Valley 23 . The model combines a detailed representation of reservoir operations, water conveyance, interbasin transfer projects, water rights, municipal and agricultural demand, and conjunctive surface and groundwater supply management, including groundwater banking operations. CALFEWS operates on a daily time step and resolves water deliveries and operations at the level of individual water providers (e.g., municipal utilities, irrigation districts, and water storage districts). This spatiotemporal resolution combined with a detailed representation of water management institutions is unique among models for California and leads to improved performance in reproducing historical system behavior, from reservoir storages and releases to interbasin transfer project pumping to groundwater banking balances 23 . Most existing water supply planning models employ longer timesteps (e.g., daily or monthly), larger spatial aggregation (e.g., regional), and simplified representation of water management institutions and/or infrastructure constraints. CALFEWS’ high-fidelity system representation allows for improved evaluation of infrastructure partnerships compared to lower-fidelity models that cannot resolve the multi-timescale dynamics of managed aquifer recharge or the multi-spatial scale distribution of water supply benefits and financial risks for local project partners (see Zeff et al. 23 and Hamilton et al. 33 for detailed discussions).

Hydroclimate in California is characterized by extreme interannual variability 51 , 52 . Over the last 20 years, the region has experienced three periods of persistent droughts that have been ended by extreme wet periods driven by atmospheric rivers. Facilitating robust management of the region’s water supply system requires simulating operations under an array of scenarios that can represent current and plausible future hydroclimatic sequences in the region. To support this modeling effort, we generate synthetic full natural flows using a two-state Gaussian Hidden Markov Model (HMM), which has been shown to be an appropriate method to capture long-term persistent drought conditions 96 , 97 . The 110-year multi-site historical full natural flow reanalysis dataset described in Zeff et al. 23 is used for training and verification of the synthetic hydrologic scenario generator. The HMM consists of two “hidden” climate states representing wet and dry conditions. Within each of these states, log-space flows are sampled from respective Gaussian distributions. Following Thyer & Kuczera 98 , we contribute a multi-site extension of the two-state HMM-based model to simultaneously generate full natural flows for 15 major watersheds in the Central Valley system. We generate 21 different 30-year sequences of multi-site correlated daily full natural flows to use within the multiobjective intelligent search step, along with another larger set of 79 additional 30-year daily streamflow sequences for the reevaluation step, so that each partnership in the final optimal tradeoff set has been evaluated on a total of 100 hydrologic scenarios of 30 years each (Supplementary Fig.  S1 ). The number of sequences simulated in the search (21) and reevaluation (79) steps are selected to balance the fidelity of the noisy performance metrics against the significant computational expense of the search. The synthetic full natural flow records are well matched to the historical record in terms of correlation, distribution, and flow duration (Supplementary Figs.  S6 , S12 , S13 , S16 ). However, the synthetic ensemble also widens the envelope of extreme high and low flows beyond the historical record, allowing for a deeper understanding of the impacts of internal hydroclimatic variability on infrastructure performance uncertainty. Finally, for two example partnerships, we also simulate performance under 20 downscaled CMIP5 climate models over the 2021–2050 period as an additional check on partnership robustness 53 , 99 . More details on the hydrologic scenario generator and the downscaled climate change scenarios can be found in Supplementary Note  S1 . Given a multi-site full natural flow record (e.g., from our synthetic scenario generator), CALFEWS uses an internal statistical reconstruction module to extrapolate inflows, snowpack levels, and other relevant hydroclimatic variables based on monthly linear regression relationships derived from historical observed data (see Zeff et al. 23 for a full description).

Each candidate infrastructure partnership is evaluated according to four decision-relevant metrics: (1) the number of water provider partners participating in the partnership; (2) the captured water gain, defined as the expected increase in total surface water deliveries across all project partners; (3) the captured water gain for non-partner water providers in the region; and (4) the cost of gains for the worst-off partner, defined as the annual debt payment divided by captured water gain for the worst-off partner in a partnership. The ideal partnership in our formulation would maximize Objective Metrics 1–3 and minimize Objective Metric 4, but given their conflicting nature, tradeoffs exist. These tradeoffs emerge because performance gains in any single objective come at the cost of giving up performance in one or more of the remaining objectives.

Each candidate infrastructure partnership is simulated and evaluated across 21 different 30-year daily hydrologic sequences from the synthetic generator in the multiobjective intelligent search step, and optimal tradeoff partnerships are then reevaluated across 79 additional 30-year sampled sequences to ensure robust generalization (see next section). Objective Metrics 2–3 are calculated by taking the expected value across sampled hydrologic scenarios and the sum across water provider partners (or non-partners in the case of Metric 3). Objective Metric 4 is calculated using the 90 th percentile across sampled hydrologic scenarios and the max (i.e., worst-case) across partners in order to favor partnerships that can provide robust affordable water supply benefits across a wide range of plausible hydrologic conditions 89 , 91 . Note that we do not include the expected value of the cost of gains as an independent metric because it is monotonically related to the expected captured water gains metric for a given infrastructure investment, and therefore, it would not introduce significant independent information or tradeoffs to the decision formulation. The 90 th percentile worst-partner formulation draws from previous efforts to define robust multiobjective problem formulations in noisy water resources simulation-optimization contexts 35 , 89 , 91 . More details on objective formulations can be found in Supplementary Note  S2 and Supplementary Table  S4 .

Multiobjective intelligent search

The Borg MOEA is a hyper-heuristic intelligent search algorithm employing auto-adaptive search operator selection, epsilon-dominance archiving, epsilon-progress stagnation detection, adaptive population sizing, and other beneficial features 58 . The Borg MOEA has been successfully employed across a range of difficult problems in water resources and engineering design characterized by high-dimensional, noisy, multimodal search spaces 100 , 101 , 102 , 103 , 104 , 105 . We employ the master-worker parallel version of the Borg MOEA, which is highly scalable on high-performance computing clusters 106 , 107 .

The Borg MOEA is used to discover the set of optimal tradeoff partnerships (i.e., non-dominated or approximately Pareto-optimal solutions) within our multiobjective intelligent search procedure (Supplementary Fig.  S1 ). We run four independent searches with different random seeds to account for the stochastic path-dependent nature of metaheuristic search algorithms 59 . The problem formulation that maps from the numeric decision vector that is optimized to the underlying infrastructure partnership that is simulated is detailed in Supplementary Note  S3 . For each seed, we run the parallelized Borg MOEA for 96 h across 32 AMD EPYC 7742 nodes (4032 cores total) on the Pittsburgh Supercomputing Center’s Bridges-2 supercomputer. In total, we test ~300,000 candidate infrastructure partnerships across the 4 seeds. The number of seeds and wall clock per seed is selected to balance the noise across seeds vs. the convergence, consistency, and diversity of solutions within each seed according to common multiobjective search metrics such as hypervolume, additive epsilon indicator, and generational distance 59 , 100 , 101 . Each seed exhibits acceptable convergence, consistency, and diversity given the constraints of our computing budget (Supplementary Fig.  S17 ).

Upon completion, we calculate the final non-dominated reference set for each of the four randomly seeded optimization trials, yielding 1146 unique infrastructure partnerships. Each of these partnerships is then reevaluated across 79 additional 30-year synthetic hydrologic sequences outside of the training set to ensure that partnerships are robust in the face of a range of plausible hydroclimatic conditions. The final optimal tradeoff set is calculated as the set of partnerships from any of the four trials that are non-dominated based on reevaluated performance. This final Pareto set contains 270 unique infrastructure investment partnerships that represent the optimal tradeoffs across the four objectives. We also evaluate the Status Quo Partnership (see next section) with respect to the same 79 hydrologic scenarios for comparison. All performance metrics reported in this study refer to performance in the reevaluation step. The epsilon-dominance parameters that define the meaningful resolution for each objective with respect to the non-dominance calculation in the MOEA search and reevaluation steps can be found in Supplementary Table  S4 .

Selection of Status Quo & compromise partnerships

We highlight two alternative partnerships in more detail in the results. The Status Quo Partnership (Fig.  5 ) is based on the real-world coalition of Friant Contractor water providers (Fig.  1 ) that are currently investing ~$50 million to rehabilitate the Friant-Kern Canal 49 , 50 . We design this partnership to mirror the existing institutional arrangement rather than being designed by our multiobjective intelligent search process. Given that the formal plans for apportioning cost shares across the partnership are not available, for the purpose of this analysis, the ownership share for each of the 16 partners is assumed to be proportional to its average historical delivery of Central Valley Project Friant water, following Hamilton et al. 33 .

By comparison, the Compromise Partnership is selected as a representative solution from the broader 270-member optimal tradeoff set that outperforms the Status Quo Partnership and performs relatively well across all four objectives. This partnership is selected through a two-step process (Supplementary Fig.  S18 ). First, we find the subset of optimal tradeoff partnerships that perform equal to or better than the Status Quo Partnership on all four aggregate objective metrics. The Compromise Partnership is then selected out of this subset by finding the partnership with the lowest worst-partner cost of gains.

110+ Best Science Investigatory Project Topics: Dive into Science

• Post author By admin
• September 29, 2023

Explore a wide range of science investigatory project topics to engage in innovative research and make significant contributions to the field.

Get ready to dive headfirst into the thrilling world of Science Investigatory Project (SIP) topics! Imagine a journey where you become a scientist, an explorer of the unknown, and a solver of real-world puzzles.

This is what SIP offers – a chance to channel your inner curiosity and creativity into the fascinating realm of science.

From unlocking the secrets of life in biology to experimenting with the wonders of chemistry, from unraveling the mysteries of the universe in physics to addressing vital environmental issues – SIP topics are your keys to a world of exploration.

In this adventure, we’ll guide you through an array of captivating SIP ideas. These topics aren’t just assignments; they’re opportunities to uncover new knowledge, make a difference, and have a blast along the way.

So, gear up for an exciting journey, as we unveil the science topics that could spark your imagination and fuel your passion for discovery. Let’s begin!

Table of Contents

What is a Science Investigatory Project?

Imagine stepping into the shoes of a scientist – asking questions, running experiments, and discovering the secrets of the world around you. That’s exactly what a Science Investigatory Project, or SIP, is all about.

At its core, a SIP is a thrilling journey of scientific exploration. It’s a project that challenges you to pick a problem, make educated guesses (that’s your hypothesis), roll up your sleeves for experiments, collect data, and connect the dots to find answers.

Here’s how it works

Step 1: the mystery.

You start with a question – something that piques your curiosity. It could be anything from “Why do plants grow towards the light?” to “What makes the sky blue?” Your SIP is your ticket to unravel these mysteries.

Step 2: The Guess

Next comes your hypothesis – a fancy word for your best guess at the answer. It’s like saying, “I think this is what’s happening, and here’s why.”

Step 3: The Detective Work

Now, it’s time for the fun part – experimenting! You set up tests, tweak variables, and observe closely. Whether you’re mixing chemicals, observing insects, or measuring temperature, you’re the scientist in charge.

Step 4: Clues and Evidence

As you experiment, you collect clues in the form of data – numbers, measurements, observations. It’s like gathering puzzle pieces.

Step 5: The “Aha!” Moment

When you analyze your data, patterns start to emerge. You connect those puzzle pieces until you have a clear picture. Does your data support your guess (hypothesis), or do you need to rethink things?

Step 6: Sharing Your Discovery

Scientists don’t keep their findings to themselves. They share them with the world. Your SIP report or presentation is your chance to do just that. You explain what you did, what you found, and why it matters.

So, why do SIPs matter? They’re not just school projects. They’re your chance to think like a scientist, ask questions like a detective, and discover like an explorer. They’re where you become the expert, the innovator, the problem-solver.

From the mysteries of biology to the wonders of chemistry and the enigmas of physics, SIPs open doors to countless adventures in science. So, what question will you ask? What mystery will you solve? Your SIP journey awaits – embrace it, and you might just uncover something amazing.

Choosing the Right SIP Topic

Choosing the right Science Investigatory Project (SIP) topic is like selecting a path for your scientific adventure. It’s a critical decision, and here’s how to make it count:

Follow Your Passion

1. Water Tank

Water tanks are storage containers of water; these tanks usually stores water for human consumption. The need for water tanks is as old as civilized man. Water tanks provide the storage of drinking water potable, irrigation,agriculture, fire suppression, agricultural farming and live stoke, chemical manufacturing, food preparation and many other applications.

Various materials are used for constructing water tanks; plastic, polyethylene, polypropylene, fiberglass, and concrete, steel (welded or bolted, carbon or stainless)

2. Autonomous Firefighting Robot

According to survey in india nearly 25,000 people die every year due to fire and related causes and the loss due to these fire incidents is more than Rs.100 crores. Even though there are lot of precaution taken to prevent the fire there are accidents happening everywhere, so we have to kill the fire before it kills us. In a fire breakout the firefighters are restricted to go near the fire as the intensity of the fire is high in some cases, In order to overcome this we can build an autonomous firefighting robot which can help the firefighters in reducing the heat of the fire.

3. Solar powered Irrigation System

One of the biggest networks where people work as groups in the field of Agriculture. As technology is increasing and automation is replacing manual operation in almost all the fields, the same can be applied to the Agricultural Field also. Previously farmers manually used to water the fields whenever needed and power for providing the water is taken from household power. The cons of this system are we need to pay for the power and every time human intervention is needed whenever water needs to be provided. Imagine there is an automatic system where whenever water is needed for the field, automatically pump will be turned on and when water level sufficient, the pump will be turned off automatically and the power required for the operation of the pump will be taken from the solar power.

4. Water Jet Cutting Tool

Water jet cutting method is one of the material removal type of rapid prototyping technique (RPT) which is been widely used in the automotive and aerospace industry to produce the complex and precise shape on a metal with minimum time and least effort being used.

In order to ensure safe and clean drinking water on board, your boat freshwater system needs to be sanitized if it hasn’t been used for some time, for example before your first use of the system after your boat has been stored for the winter. In order to clean boat water tanks, you have to remove the old water before starting the disinfection procedure.

11. Salt Light Lamp

The idea behind this project salt lamp is the chemical conversion of energy. It utilizes the scientific process behind the Galvanic cell, but instead of electrolytes, the SALt lamp uses saline solution, making it harmless and non-toxic. SALt lamp project is an LED lamp powered by the galvanic reaction of an anode with saline water. It also has a USB port to charge low-power mobile devices such as cellphones, smartphones, and mp3 players.The anode must be replaced approximately every six months and the saline water daily; sea water is usable.

12. Water Management and Leakage Detection System using Arduino

Water is the world’s most precious resource, yet it is also the one which is almost universally mismanaged. As a result, water shortages are becoming ever more common. Leakages, overflow of water and bursting of pipes these all most common in waste of water. So as to detect all these problems here you are going to work on the building, tank water level sensing monitoring and water pipeline leakage sensing monitoring system.

13. Project on Ground Improvement using Stone Column

In order to enhance infrastructure projects, large civil engineering projects are executed in India. Due to space constraints and time limits infrastructure facilities have to often build on site where the soil conditions are not ideal. This is where the geotechnical engineer plays a critical role in improving the soil conditions. The method of ground improvement adopted depends upon the nature of strata and the purpose of improvement. Under different improvement techniques, ground improvement using stone columns offers a proven and economical solution. In this project, you are going to make a stone column with different composition to know which composition gives more strength to the soil.

14. Comparison of Strength Characteristics of Concrete Made by TSMA using Fly Ash and Nominal Concrete Made by NM Approach

It is known that wastage in India in the construction industry is as high as 30%. This is a large, yet relatively simple and straightforward challenge needs to be tackled by engineers. These wastages are activities that absorb man hours, resources and materials but create no value. In this project, you will use those waste materials to make something productive by making a concrete using recycled aggregate and fly ash. After making concrete you will compare the compressive as well as flexural strength characteristics of the concrete made through NMA and TSMA.

40. Sustainable Energy Generation from Septic Tank

Non-renewable energy sources are coming to an end as they are depended on the sources like coal, petrol. So, renewable energy generation is the right way to overcome energy demands.

Electricity is one of the important social need and many types of research are also going on in the generation of non-conventional electricity. Many countries are investing a large amount of money over renewable energy sources like solar energy and wind energy. But it consumes more space as well as a huge capital to build. They also cause pollution to the environment and need much manpower. It also requires raw materials to construct the setup.

Septic tanks are built in every residential house. The function of the septic tank is to reduce the pollution and content of pollutants in the wastewater. This is automatically done by the anaerobic bacteria that live in the septic tank. The septic tank provides favourable conditions for these anaerobic bacteria. This bacteria feeds on the organic material that presents in human waste and converts them into H+ ions and also produce a slight amount of methane gas.

41. Water Purification using the Pedal System

Earth is also known as the blue planet as 75% of its surface is covered by the water. But there is a lack of drinking water on earth. This is because only 2% of 75% of water is meant for drinking and irrigation purpose.

42. Underwater Turbines

We are in an era where we can’t live without electricity even for ten minutes. The major proportion of electricity is produced is from non-conventional or non-renewable sources. Thermal power station alone accounts for about 70 - 80% of the electricity generation.  And the remaining is produced by hydro, wind, etc.

43. Measurement of soil water Using Ground penetrating Radar

It is very important to measure soil water content. The change in the content of water in the soil will have significant influence over the deformation characteristics and strength of the soil. It also affects groundwater flow and surface constructions.

47. IoT-Water Tank Filling system

  Introduction:

Water is an important resource for our planet. We should not waste it and try to regulate its use. There is a constant decrease in water levels in the environment. Currently, water in urban areas comes for a specific period and an individual is needed to present physically to switch on the pumps, store water and then again switch it off once the tank is filled. If a person forgets to switch off the pump on time then a lot of water is wasted and if the person is not available on time to switch on the pump, then they will have to face difficulty due to the unavailability of water. This IoT project focuses on this issue and eliminates the need for a person. It automatically switches on the pump when water comes, and will switch it off once the tank is filled. Many people have installed this in their houses and find it effective.

48. IoT based Flood detection and Prevention system using ESP8266

It is a smart machine that closely monitors different natural aspects to forecast flooding so that we can take care to mitigate flood damage. Natural catastrophes such as earthquakes can be disastrous, eventually led to the destruction of assets and life loss. The device uses different natural parameters to predict flooding and minimize or reduce the flood effects. The device has a Wi-Fi connection, and data obtained can be viewed very conveniently from almost anywhere using IoT.

49. Arduino based smart irrigation monitoring and controller system using ESP8266

Farmers normally operate on broad portions of the field to develop numerous crop varieties. It's not always easy for a single person to maintain control of the entire agricultural land all the time.

This commitment to DEI not only strengthens design-build project delivery but also ensures the benefits of these projects are shared equitably across all segments of society. 

Judging the Best of the Best

True to DBIA’s commitment to excellence, the judging process for these awards is rigorously conducted by industry experts who convene for two days to assess projects based on best practices, innovation and the project’s ability to meet or exceed Owner expectations. Judges bring an array of experience and skills to the review process to ensure projects are evaluated across a broad range of factors. Winning projects must go beyond ticking the boxes of a design-build project –– achieving budget goals, remaining on schedule and meeting design-build best practices –– to demonstrate the advanced and standard-raising application of integrated project delivery. 

“As design-build approaches nearly half of all construction spending, we continue to see extraordinary projects that raise the bar for design-build teams across the country, pushing the limits of high performance and optimizing triple-bottom-line success,” DBIA Executive Director/CEO Lisa Washington, CAE, said.

70 Best High School Science Fair Projects in Every Subject

Fire up the Bunsen burners!

The cool thing about high school science fair projects is that kids are old enough to tackle some pretty amazing concepts. Some science experiments for high school are just advanced versions of simpler projects they did when they were younger, with detailed calculations or fewer instructions. Other projects involve fire, chemicals, or other materials they couldn’t use before.

Note: Some of these projects were written as classroom labs but can be adapted to become science fair projects too. Just consider variables that you can change up, like materials or other parameters. That changes a classroom activity into a true scientific method experiment!

To make it easier to find the right high school science fair project idea for you, we’ve rated all the projects by difficulty and the materials needed:

Difficulty:

• Easy: Low or no-prep experiments you can do pretty much anytime
• Medium: These take a little more setup or a longer time to complete
• Advanced: Experiments like these take a fairly big commitment of time or effort
• Basic: Simple items you probably already have around the house
• Medium: Items that you might not already have but are easy to get your hands on
• Advanced: These require specialized or more expensive supplies to complete
• Biology and Life Sciences High School Science Fair Projects

Conversational AI Powered by Large Language Models Amplifies False Memories in Witness Interviews

This study examines the impact of AI on human false memories--recollections of events that did not occur or deviate from actual occurrences. It explores false memory induction through suggestive questioning in Human-AI interactions, simulating crime witness interviews. Four conditions were tested: control, survey-based, pre-scripted chatbot, and generative chatbot using a large language model (LLM). Participants (N=200) watched a crime video, then interacted with their assigned AI interviewer or survey, answering questions including five misleading ones. False memories were assessed immediately and after one week. Results show the generative chatbot condition significantly increased false memory formation, inducing over 3 times more immediate false memories than the control and 1.7 times more than the survey method. 36.4% of users' responses to the generative chatbot were misled through the interaction. After one week, the number of false memories induced by generative chatbots remained constant. However, confidence in these false memories remained higher than the control after one week. Moderating factors were explored: users who were less familiar with chatbots but more familiar with AI technology, and more interested in crime investigations, were more susceptible to false memories. These findings highlight the potential risks of using advanced AI in sensitive contexts, like police interviews, emphasizing the need for ethical considerations.

Manipulation of Eyewitness Memory by AI: This figure illustrates the process of AI-induced false memories in three stages. It begins with a person witnessing a crime scene involving a knife, then shows an AI system introducing misinformation by asking about a non-existent gun, and concludes with the witness developing a false memory of a gun at the scene. This sequence demonstrates how AI-guided questioning can distort human recall, potentially compromising the reliability of eyewitness testimony and highlighting the ethical concerns surrounding AI’s influence on human memory and perception.

The Generative Chatbot significantly induced more immediate false memories compared to other interventions

(Left) The average number of immediate false memories result was analyzed using a one-way Kruskal–Wallis test and posthoc Dunn test with FDR.

How To : The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.

What's an Investigatory Project Exactly?

An investigatory project is basically any science experiment where you start with an issue or problem and conduct research or an investigation to decide what you think the outcome will be. After you've created your hypothesis or proposal, you can conduct a controlled experiment using the scientific method to arrive at a conclusion.

What's the Scientific Method?

For those of us who have forgotten the various steps of the scientific method, let me clear that up right here:

Remember, however, that a successful investigatory science project does not necessarily have to result in the intended outcome. The purpose of these projects is to think critically, and if the solution doesn't work out, that doesn't mean your project will fail.

What Kind of Investigatory Projects Are There?

In order to conduct a great investigatory experiment, you have to ask an interesting question and be able to conduct an experiment that can hopefully answer that question. The harder and more intriguing the initial question is, the better the resulting investigation and experiment will be.

I've listed a few examples below of some of the best investigatory experiments out there, so hopefully you'll have no problem coming up with an idea.

Project #1: Making Soap Out of Guava

Basic hygiene should be available to everyone, but what about people who live in areas without easy access to grocery stores or pharmacies? This is a great question that makes you think about scientific alternatives to store-bought soap.

Below is an example project that creates soap from guava leaf extract and sodium hydroxide, but there's no shortage of materials you can use to replace the guava, like coconut oil or a fat like lard, butter or even the grease from your kitchen .

Project #2: Used Cooking Oil as a Substitute for Diesel

We all know how lucrative the oil business is, but what if the next huge innovation in oil was sitting right inside your kitchen cabinet? With the high prices of regular gasoline and diesel fuel, the possibility of creating a usable diesel fuel from household cooking oils is pretty exciting.

Although creating diesel fuel out of cooking oils that will run a BMW may sound like a reach, it still makes for a great project. And who knows, maybe in doing this you'll actually figure out what was missing from previous attempts . Being an instant billionaire doesn't sound too bad to me.

If you're interested in trying it for yourself, there's a great step-by-step guide with a full ingredients list and photos over on Make .

Project #3: Create Another Alternative Fuel

If biodiesel isn't your forte, you can try making oxyhydrogen gas or creating hydrogen gas via electrolysis or vice versa, creating electricity from hydrogen gas .

Project #4: Purifying Used Cooking Oil

Speaking of oil, if you use it to cook, you know that a lot of it goes to waste. But what if you could clean that oil and use it over and over again? Not only would that save money, but it would also benefit the environment since most people do not properly dispose of used cooking oil (no, pouring it down the drain doesn't count).

Your project goal would be to research methods of filtration or purification and test it on cooking oils. To easily demonstrate which method works best, try cooking some food in the oil produced by each one. Good food can go a long way when it comes to winning people over.

Check out the abstract and description of a similar project here .

Project #5: Alternative Methods of Producing Iodized Salt

In areas isolated from the sea, IDD or Iodine Deficiency Disease, is very common. Since these areas do not have easy access to marine foods or grocery stores, the population becomes very susceptible to the disease due to a lack of iodine in the diet. In order to combat this, researchers and doctors have begun infusing iodine into regular table salts.

If not iodine is readily available, it can be chemically made either with sulfuric acid and alkali metal iodide or hydrochloric acid and hydroxide peroxide .

But perhaps there are other more accessible ways to create an iodized salt that people could make at home. For a starting point, take a look at this previous experiment .

Project #6: Making Biodegradable Plastic

Plastic bags are actually illegal in Santa Monica , CA (and soon to be Los Angeles ) because of their threat to the environment due to insane resistance to biodegradation. I didn't think they were that bad, but one plastic bag can take up to 1,000 years to break down completely, and it can even ruin your car along the way. So, creating a better biodegradable plastic bag would be a huge achievement.

The only question is how one would go about doing so, and what materials could be used? That's the question you can answer for your project. This project used cassava starch as an effective component for a biodegradable plastic, but you could try using a few different starches and see what works best.

Project #7: Solar Water Purification

One of the biggest world problems is finding clean water. While we in the states can find purified or drinkable tap water almost anywhere, millions of people around the world don't have access to clean drinking water.

A few students decided to investigate a potential purification process using the sun's energy and an aluminum sheet. Watch the video below for more information and a complete walkthrough of their scientific process.

And if you're an overachiever, you can step it up a notch and try purifying pee instead .

Project #8: Perfecting the Paper Bridge

Of course, an investigatory project doesn't always have to answer such grand questions. This experiment looks to discover how to build the strongest paper bridge by varying how the pieces are held together. So, the question is, "How do design changes affect a load bearing structure?"

Check out the video below for more information on replicating the project yourself.

Project #9: Making Instant Ice

It's summer time and the degrees are already hitting triple digits in some areas. When it's this hot, there are few things better than a glass of ice chilled water or lemonade. But what happens if you don't have ice? Can you create your own ice or cool drinks quickly by another method? Check out this clip from King of Random .

Cool, huh? But how does it work? Is there any other way to replicate this? Well, let the investigation begin. Figure out what your hypotheses will be and follow along with this video for you own investigatory project.

For more information and additional photos, be sure to check out the King of Random's full tutorial .

Project #10: Increase the Shelf-Life of Fruits and Veggies

Extending the shelf-life of perishable fruits and vegetables can make a huge difference for small farmers, street-side vendors and even your average Joe—groceries aren't cheap. What is an inexpensive and easily accessible way to make produce stay fresh longer?

That's the question behind this great investigatory science project featured here . While these researchers focused exclusively on chitosan coating on bananas, you can branch out (no pun intended) and try an assortment of other fruits, veggies and possible coating materials.

For more information on how to keep your fruits and vegetables fresh for longer, check out my previous article , or Yumi's recent illustration for other ideas.

Project #11: Slow the Ripening of Sliced or Chopped Produce

You could also focus your project on keeping fruits and vegetables from browning after they've already been cut up. There are various methods and materials you can use to slow down the ripening process, such as honey and lemon juice. Watch the video below and read this tutorial for more information and ideas.

Your project could revolve around finding the best option, and testing out some of your own browning-prevention solutions to see if you can come up with a better one.

Project #12: Improve Memory by Thinking Dirty

If my memory was any good I would be fluent in Spanish and never need to look up the Quadratic Formula again. But my problems are more superficial, like forgetting where I put my keys or what time my dentist appointment was supposed to be. There are folks out there who do suffer from real memory problems, so figuring out how to help improve memory makes for a great investigatory project.

There are tons of studies on memory and memory loss that you can research. But for your investigatory science project, you will want to come up with your own hypothesis based on that information and test it out. Does using colors to form associations help with memory? Does linking an image with a memory increase its hold in the carrier's head? What about drinking grape juice or sniffing rosemary ? These are the types of questions you may look to answer.

This article contends that memory can be improved by looking at NSFW images or thinking of dirty associations. Come up with your own theory and let the brain hacking begin.

Project #13: Improving Social Anxiety by Manipulating the Body & Mind

Science experiments don't always have to include chemicals or test tubes. The science of the mind can be just as interesting. So what's the investigation consist of?

Can you truly affect the way you act and feel by simply changing your posture? Does acting a certain way manipulate the mind drastically enough to actually change the way you feel?

Check out Amy Cuddy's awesome TED Talk for more ideas for additional questions you could ask.

Project #14: Kitchen DNA Extraction

You may think studying DNA is only for professionals with super expensive lab equipment, but you can actually extract DNA from any living thing with a few basic ingredients you probably have in your kitchen like dish soap and rubbing alcohol.

Decide on something to vary, like different fruits and vegetables or types of dish soap, and come up with a hypothesis regarding which will allow you to collect the most DNA material.

You can also find more information, as well as another way to perform the experiment, here .

Project #15: Make Homemade Glue from Milk

With milk, white vinegar and baking soda, you can make your own glue right at home. Make it an investigatory project by changing up the recipe and testing which results in the strongest glue. You could also try varying the ingredients to make it dry faster, or work on different materials (wood vs. plastic vs. paper).

Project #16: Make a Battery Out of Fruits and Vegetables

How can you power a small light or device without electricity? You can make a DIY battery with a few different types of fruits and vegetables. Anything from a lemon to an apple , potato , or even passion fruit will work.

Pick a few different fruits or vegetables and form a hypothesis as to which will make the battery that puts out the most energy or lasts the longest. Once you've built your batteries, hook up a volt meter to read the output and see which one is the best.
