50 Best Environmental Science Research Topics

May 31, 2023

Environmental science is a varied discipline that encompasses a variety of subjects, including ecology, atmospheric science, and geology among others. Professionals within this field can pursue many occupations from lab technicians and agricultural engineers to park rangers and environmental lawyers. However, what unites these careers is their focus on how the natural world and the human world interact and impact the surrounding environment. There is also one other significant commonality among environmental science careers: virtually all of them either engage in or rely on research on environmental science topics to ensure their work is accurate and up to date.

In this post, we’ll outline some of the best environmental science research topics to help you explore disciplines within environmental science and kickstart your own research. If you are considering majoring in environmental science or perhaps just need help brainstorming for a research paper, this post will give you a broad sense of timely environmental science research topics.

What makes a research topic good?

Before we dive into specific environmental science research topics, let’s first cover the basics: what qualities make for a viable research topic. Research is the process of collecting information to make discoveries and reach new conclusions. We often think of research as something that occurs in academic or scientific settings. However, everyone engages in informal research in everyday life, from reading product reviews to investigating statistics for admitted students at prospective colleges . While we all conduct research in our day-to-day lives, formal academic research is necessary to advance discoveries and scholarly discourses. Therefore, in this setting, good research hinges on a topic in which there are unanswered questions or ongoing debates. In other words, meaningful research focuses on topics where you can say something new.

However, identifying an interesting research topic is only the first step in the research process. Research topics tend to be broad in scope. Strong research is dependent on developing a specific research question, meaning the query your project will seek to answer. While there are no comprehensive guidelines for research questions, most scholars agree that research questions should be:

1) Specific

Research questions need to clearly identify and define the focus of your research. Without sufficient detail, your research will likely be too broad or imprecise in focus to yield meaningful insights. For example, you might initially be interested in addressing this question: How should governments address the effects of climate change? While that is a worthwhile question to investigate, it’s not clear enough to facilitate meaningful research. What level of government is this question referring to? And what specific effects of global warming will this research focus on? You would need to revise this question to provide a clearer focus for your research. A revised version of this question might look like this: How can state government officials in Florida best mitigate the effects of sea-level rise?

 2) Narrow

Our interest in a given topic often starts quite broad. However, it is difficult to produce meaningful, thorough research on a broad topic. For that reason, it is important that research questions be narrow in scope, focusing on a specific issue or subtopic. For example, one of the more timely environmental science topics is renewable energy. A student who is just learning about this topic might wish to write a research paper on the following question: Which form of renewable energy is best? However, that would be a difficult question to answer in one paper given the various ways in which an energy source could be “best.” Instead, this student might narrow their focus, assessing renewable energy sources through a more specific lens: Which form of renewable energy is best for job creation?

 3) Complex

As we previously discussed, good research leads to new discoveries. These lines of inquiry typically require a complicated and open-ended research question. A question that can be answered with just a “yes” or “no” (or a quick Google search) is likely indicative of a topic in which additional research is unnecessary (i.e. there is no ongoing debate) or a topic that is not well defined. For example, the following question would likely be too simple for academic research: What is environmental justice? You can look up a definition of environmental justice online. You would need to ask a more complex question to sustain a meaningful research project. Instead, you might conduct research on the following query: Which environmental issue(s) disproportionately impact impoverished communities in the Pacific Northwest? This question is narrower and more specific, while also requiring more complex thought and analysis to answer.

4) Debatable

Again, strong research provides new answers and information, which means that they must be situated within topics or discourses where there is ongoing debate. If a research question can only lead to one natural conclusion, that may indicate that it has already been sufficiently addressed in prior research or that the question is leading. For example, Are invasive species bad? is not a very debatable question (the answer is in the term “invasive species”!). A paper that focused on this question would essentially define and provide examples of invasive species (i.e. information that is already well documented). Instead, a researcher might investigate the effects of a specific invasive species. For example: How have Burmese pythons impacted ecosystems in the Everglades, and what mitigation strategies are most effective to reduce Burmese python populations?

Therefore, research topics, including environmental science topics, are those about which there are ample questions yet to be definitively answered. Taking time to develop a thoughtful research question will provide the necessary focus and structure to facilitate meaningful research.

10 Great Environmental Science Research Topics (With Explanations!)

Now that we have a basic understanding of what qualities can make or break a research topic, we can return to our focus on environmental science topics. Although “great” research topics are somewhat subjective, we believe the following topics provide excellent foundations for research due to ongoing debates in these areas, as well as the urgency of the challenges they seek to address.

1) Climate Change Adaptation and Mitigation

Although climate change is now a well-known concept , there is still much to be learned about how humans can best mitigate and adapt to its effects. Mitigation involves reducing the severity of climate change. However, there are a variety of ways mitigation can occur, from switching to electric vehicles to enforcing carbon taxes on corporations that produce the highest carbon emission levels. Many of these environmental science topics intersect with issues of public policy and economics, making them very nuanced and versatile.

In comparison, climate change adaptation considers how humans can adjust to life in an evolving climate where issues such as food insecurity, floods, droughts, and other severe weather events are more frequent. Research on climate change adaptation is particularly fascinating due to the various levels at which it occurs, from federal down to local governments, to help communities anticipate and adjust to the effects of climate change.

Both climate change mitigation and adaptation represent excellent environmental science research topics as there is still much to be learned to address this issue and its varied effects.

2) Renewable Energy

Renewable energy is another fairly mainstream topic in which there is much to learn and research. Although scientists have identified many forms of sustainable energy, such as wind, solar, and hydroelectric power, questions remain about how to best implement these energy sources. How can politicians, world leaders, and communities advance renewable energy through public policy? What impact will renewable energy have on local and national economies? And how can we minimize the environmental impact of renewable energy technologies? While we have identified alternatives to fossil fuels, questions persist about the best way to utilize these technologies, making renewable energy one of the best environmental science topics to research.

3) Conservation

Conservation is a broad topic within environmental science, focusing on issues such as preserving environments and protecting endangered species. However, conservation efforts are more challenging than ever in the face of a growing world population and climate change. In fact, some scientists theorize that we are currently in the middle of a sixth mass extinction event. While these issues might seem dire, we need scientists to conduct research on conservation efforts for specific species, as well as entire ecosystems, to help combat these challenges and preserve the planet’s biodiversity.

4) Deforestation

The Save the Rainforest movement of the 1980s and 90s introduced many people to the issue of deforestation. Today, the problems associated with deforestation, such as reduced biodiversity and soil erosion, are fairly common knowledge. However, these challenges persist due, in part, to construction and agricultural development projects. While we know the effects of deforestation, it is more difficult to identify and implement feasible solutions. This is particularly true in developing countries where deforestation is often more prevalent due to political, environmental, and economic factors. Environmental science research can help reduce deforestation by identifying strategies to help countries sustainably manage their natural resources.

Environmental Science Topics (Continued)

5) urban ecology.

When we think of “the environment,” our brains often conjure up images of majestic mountain ranges and lush green forests. However, less “natural” environments also warrant study: this is where urban ecology comes in. Urban ecology is the study of how organisms interact with one another and their environment in urban settings. Through urban ecology, researchers can address topics such as how greenspaces in cities can reduce air pollution, or how local governments can adopt more effective waste management practices. As one of the newer environmental science topics, urban ecology represents an exciting research area that can help humans live more sustainably.

6) Environmental Justice

While environmental issues such as climate change impact people on a global scale, not all communities are affected equally. For example, wealthy nations tend to contribute more to greenhouse-gas emissions. However, less developed nations are disproportionately bearing the brunt of climate change . Studies within the field of environmental justice seek to understand how issues such as race, national origin, and income impact the degree to which people experience hardships from environmental issues. Researchers in this field not only document these inequities, but also identify ways in which environmental justice can be achieved. As a result, their work helps communities have access to clean, safe environments in which they can thrive.

7) Water Management

Water is, of course, necessary for life, which is why water management is so important within environmental science research topics. Water management research ensures that water resources are appropriately identified and maintained to meet demand. However, climate change has heightened the need for water management research, due to the occurrence of more severe droughts and wildfires. As a result, water management research is necessary to ensure water is clean and accessible.

8) Pollution and Bioremediation

Another impact of the increase in human population and development is heightened air, water, and soil pollution. Environmental scientists study pollutants to understand how they work and where they originate. Through their research, they can identify solutions to help address pollution, such as bioremediation, which is the use of microorganisms to consume and break down pollutants. Collectively, research on pollution and bioremediation helps us restore environments so they are sufficient for human, animal, and plant life.

9) Disease Ecology

While environmental science topics impact the health of humans, we don’t always think of this discipline as intersecting with medicine. But, believe it or not, they can sometimes overlap! Disease ecology examines how ecological processes and interactions impact disease evolution. For example, malaria is a disease that is highly dependent on ecological variables, such as temperature and precipitation. Both of these factors can help or hinder the breeding of mosquitoes and, therefore, the transmission of malaria. The risk of infectious diseases is likely to increase due to climate change , making disease ecology an important research topic.

10) Ecosystems Ecology

If nothing else, the aforementioned topics and their related debates showcase just how interconnected the world is. None of us live in a vacuum: our environment affects us just as we affect it. That makes ecosystems ecology, which examines how ecosystems operate and interact, an evergreen research topic within environmental science.

7 Key Research Areas That Could Help Solve the Plastic Crisis

At the forefront of our technological advances are researchers that dedicate their career to investigating and studying the possibility of new innovations. Without research, our world would not experience progress and problems posed against humanity would go unanswered. As plastic pollution remains one of the world’s biggest environmental problems, targeted scientific research is key to finding solutions to the pervasive issue. Here are 7 key research areas that will help us progress further in solving the plastic crisis. 

Aside from technological advancements and inventions, targeted area research will bring imperative benefits in tackling the plastic crisis. Without it, scientists would not have uncovered the plastic-eating enzyme that will play an important role in drafting further future solutions, and we would not have discovered that our current NASA technology used to predict extreme weather can also be used to monitor and track microplastics in our oceans. 

Needless to say, research is fundamental to pioneering groundbreaking technology, as well as finding solutions to political issues and governance within our communities. The journal One Earth published an article asking leading researchers in the industry what they believe the best science-based research to the solution to the plastic crisis should be. This has been summed up in the following:

• Enforcing Political Change 

Tamara Golloway from the University of Exeter believes that unsustainable use of plastic is widely occurring around the world. To alleviate the plastic crisis, she asserts that we need research on how we tackle the plastic crisis on a political level.  This includes adopting “circular-economy approaches to focus on creating closed-loop resource flows that can keep products in use longer, thereby reducing waste and carbon budgets, and conserving natural resources.” Galloway implies that the current use and shelf-life of plastic is unsustainable, and we need to bring together governments and scientific researchers to find ways in which plastic can be used in a more sustainable way. 

Britta Denise Hardesty from Commonwealth Scientific and Industrial Research Organisation also believes that research should be conducted into political change in the form of a plastic tax that incorporates the true social cost of plastic. 

“When we put a price on plastic, when we value the many polymers that compose the plastics in society today, and when we incorporate the true costs into what we pay for these materials – from pellet form to finished product and from manufacturing to recovery – we will not only wasteless but also design better and smarter,” said Hardesty. 

• Plastic Governance 

Marcus Haward of University of Tasmania believes that more research should be carried out on the governance of plastic, focusing specifically on its production and use, as current regulations and government responses have failed to properly address plastic waste. 

“Plastic pollution is a case of regulatory, market, and community failure, and so traditional governance responses such as looking to market instruments to address regulatory failure or community actions to address market failures are insufficient,” stated Haward. 

• Plastic Pollution on Human and Ecosystem Health 

Sherri A Mason of Penn State Behrend believes that to ignite collective action, more research is needed studying the effects of plastic pollution on human health and what it is directly doing to our bodies. 

“The research questions at the forefront of plastic pollution research and those that are most likely to lead to real solutions are those that are looking at the impact of plastic pollution, specifically micro-and nanoplastics, on human health,” Mason said. “When people know it is affecting them and/or their children and other loved ones, they will demand action and our representatives will be hard pressed to rationalise anything but.”

Alice Horton of National Oceanography Centre agrees, adding that research should also look into its effects on ecosystems, food chains and human health. “Understanding the distribution and forms of plastics in the environment will help us to better understand ecosystem exposure and to predict accumulation and hazard,” Horton said. “Further investigating the harm that different types of plastics can cause will ultimately help us to target those that are the biggest threats, i.e., the ‘‘problem plastics,’’ and thus implement strategies to reduce the production of these products and their effect on the environment.”

• Plastic Consumption

Joshua O Babayemi of Anchor University in Lagos believes research should be carried out on the consumption of plastic and ways in which they can be modified to make them recyclable and sustainable for the economy. Babayemi notes that there is a huge issue of unrecyclable plastic bags dominating their economies in Africa. “Despite the global outcry against plastic littering and pollution, these ‘‘unrecyclable’’ plastics currently litter almost every street and make up a major component of wastes in all dumpsites,” Babayami stated. “It is not uncommon to see plastic bags caught on plants.”

Babayemi added: “This raises several research questions. Why are these categories of plastic wastes not usually sought after by recyclers in African countries? Can deposit return schemes be a way out? Is the continent ripe for a complete ban of single-use plastics? Can the composition of plastic bags be modified to be more suitable for recycling? Finding the answers will be a critical step in addressing plastic pollution in Africa.”

• Plastic Sources, Sinks and Transport Pathways 

Stefan Krause of the University of Birmingham believes we need further research into the sources, sinks and transport pathways of plastic. This would mean investigating how plastic is altered throughout its journey into the economy, and how these alterations are affecting aquatic life, human health and ecosystems. 

“There are still severe knowledge gaps in understanding the principles that govern the spatial and temporal dynamics of plastic transport and accumulation in river corridors,” stated Krause. “This includes how microplastic particles are altered during transport – how they degrade in freshwater environments, how they enter and propagate through food webs, and ultimately how they affect human and environmental health.”

• Bioplastic and Plastic Alternatives 

Joleah Lamb of the University of California Irvine argues we need to put our attention towards technological and innovative advancements of bioplastics. There’s currently a “social hesitation” in the use of plastic alternative materials, which warrants further research in this key area. Lamb stresses that social understanding is imperative. 

When discussing replacing plastic with bioplastic, she asserts that “transforming a waste stream into the main component of a new product might not be well received by consumers, resulting in low uptake despite the positive environmental impact.” 

“For example, when several leading car companies started using plant-based wiring, concerned consumers filed class-action lawsuits, and the products were withdrawn,” she added. 

• Tracking and Monitoring Plastic

Ivan A Hinojosa of Universidad Catolica de la Santısima Concepcion highlights the need to examine approaches in tracking plastics through the use of chemical markers that enable labelling and identification. He further believes that large companies need to be held responsible for their negligence. “The big producers of plastic pollution must be held responsible,” Hinojosa said. “The scientific community could potentially facilitate producer accountability by investigating approaches to tracking plastics through chemical markers that enable labelling and identification.” 

What’s Next? 

It is clear that targeted key research is just as imperative as the technology created by our inventors and engineers. To support the furtherance of such research discussed above, governments need to prioritise environmental issues in their agenda. For instance, The Organisation for Economic Co-operation and Development (OECD) released a report providing countries with a Green Budgeting Framework that can help governments achieve their environmental and climate goals. 

In redirecting their budget and ensuring that they are investing enough money to help fund the expansion and future of these types of research, we might have a change in tackling global pervasive problems including plastic pollution.

The Chesapeake Bay Plastic Survey is intended to assess the necessity and to generate a baseline for a future monitoring effort for plastics pollution trends in the Chesapeake Bay watershed. Awarded the Woodward and Curran’s Impact Grant, Ocean Research Project will assess bay-wide plastic pollution by exploring plastic particle count as a water quality indicator for monitoring future bay health. In cooperation with its partners, ORP hopes to repeat this project biannually to enrich understanding of the Bay-wide magnitude of plastic pollution, export to the ocean, and how that is changing relative to Bay improvements and climate change.

ORP’s study will be the first to determine particle concentration of plastic pollution across the United States’ largest estuary, the Chesapeake Bay. The information from this pilot project will be used to inform a dedicated multi-year sampling program by the Chesapeake Bay Program partners at the federal, state, and local levels.

The abundance of plastic garbage created by modern human civilization has infiltrated the deepest trenches of the world’s oceans and concentrated in huge areas on its surface. An estimated 5.5 trillion pieces of plastic debris are in the world’s oceans. There are countless sources of this plastic debris, but virtually all of it originates on land through the overuse of plastics in our daily lives and improper waste disposal. Once plastic trash enters the Ocean, nature’s forces and the migration of marine species and birds determine how the plastic material and chemical compounds move and accumulate through the complex marine environment, including the food chain and the Plastisphere. Much of this plastic debris is concentrated at the centers of enormous oceanic current circulation regions, called gyres.

We know a little more about chemical transfer risk in the sea food chain. Check out our collaborative publication in Marine Pollution Bulletin to find out more… Here

To better understand the nature of plastic debris in the Ocean, ORP has conducted multiple research expeditions in the Atlantic, Pacific, and Arctic Oceans. ORP completed its first marine debris research expedition in 2013. During this trip, its crew spent 70 days sailing in the Atlantic Ocean, collecting samples of plastic trash in the water and mapping out the eastern side of the North Atlantic garbage patch. The following year, ORP embarked upon a second expedition to research microplastic pollution in the Pacific Ocean. During this trip, ORP’s crew sailed 6,800 miles nonstop from San Francisco to Yokohama, Japan, collecting microplastic samples along the trans-pacific route.

Due to the flexibility offered by doing research from a sailboat, ORP’s expeditions could dedicate more time to collecting data samples across a much broader area than other similar types of marine research expeditions would typically cover. ORP’s research has provided an essential baseline for marine surface debris data and improved knowledge of the concentration, composition, and extent of plastic debris in the Ocean. ORP conducted its research to ensure the samples could be used to support further research being done as part of plastic pellet toxicity studies at the University of Tokyo’s Pelletwatch program. In addition, ORP’s research was designed to allow ORP and participating scientists to define further the diversity of the Plastisphere, specifically the roles played by bacteria and viruses in their evolving relationships with plastic debris in the Ocean.

ORP’s research expeditions targeting the investigation of northern hemisphere subtropical gyres of the Atlantic and Pacific Ocean and well as the western Arctic’s plastic pollution in the marine environment have helped increase the scientific community’s understanding of plastic’s pollution’s pervasive distribution across oceans from the sea ice to the seabed. The extensive datasets and that ORP collected, processed and regional interpretation during these expeditions contributed to the following publications:

• Plastic Pollution in the World’s Oceans: More than 5 Trillion Plastic Pieces Weighing over 250,000 Tons Afloat at Sea  
• PCBs and PBDEs in microplastic particles and zooplankton in open water in the Pacific Ocean and around the coast of Japan
• Mitigation strategies to reverse the rising trend of plastics in Polar Regions

To date, ORP has sailed tens of thousands of miles, spent many months at sea, and a considerable amount of time in labs back on land sorting the samples and data. During our extended periods of time at sea, there was not one day that went by where we did not see foraging birds mistaking marine debris for food. The fight to prevent pollution from plastic debris in the ocean is best fought at the primary source, on land.

10 Hands-On Science Projects to Teach About Pollution

And then there is plastic pollution. According to an article by  National Geographic, some 18 billion pounds of plastic waste flows into the oceans every year from coastal regions. The problem is, this plastic destroys local habitats and is known to be a contributing factor to animal mortality.  Clearly, something drastic needs to be done about the surge of pollution. And these are just a few examples.

Education is certainly part of improving the situation. Teachers can educate their students so they can make a difference – whether it be in their own personal lives, or as the environmental scientists and inventors in the future.

To spark the inner environmentalist in students, we’ve compiled a list of the best hands-on science projects that teach kids about pollution. We have also suggested what grades each activity is suitable for. However, these are just a guide, so feel free to use your discretion and adapt each activity to the grade you are teaching.

1. Oil Spill Simulation

Oil spills are devastating for the environment, and cost millions of dollars to clean up. Videos and images of oil spill disasters can be an effective teaching tool since they can be so emotional. Although caution is advised when showing pictures of affected animals!

Nevertheless, a hands-on oil spill simulation will help your students to understand why oil spills affect the environment so badly and how difficult they are to clean up. You can find specific instructions for this activity here . In a nutshell, the activity requires students to simulate an oil spill in a tray of water, examine the potential effects on wildlife, and suggest clean-up methods using household items.

Suitable for: 3 – 6

2. Real-World Testing of Biodegradability

If objects and materials were more biodegradable, this would help with pollution since the discarded objects would break down more quickly. Some of the materials we use, however, never break down, and they end up clogging up our waterways and littering our soil. In this activity, students will conduct an experiment that establishes what materials really are biodegradable.

You can find instructions  here . It essentially involves burying a range of objects (an apple core, leaves, plastic packaging, and Styrofoam) underneath the ground and leaving them there for a month. Students then return to the burial site and dig down to see what has broken down and what has not. The activity also comes with some excellent discussion questions. 

Suitable for: K – 6

For more ideas, see  Activity # 14 Renewable or Not? in PLT’s  PreK-8 Environmental Education Activity Guide .

3. “Happy Earth, Sad Earth” Sorting Game

This activity is a very simple sorting exercise for younger children. It involves putting pictures of things that are beneficial for the Earth, and those that are not, into the appropriate category. The activity could be conducted in groups, or as a class.

For this activity, you will need to print out and laminate (optional) the cards and objects found here (courtesy of www.totschooling.net ). How you encourage your students to sort the objects is entirely up to you, but displaying them on a big piece of cardboard that can be put up on the wall when finished is ideal! 

Suitable for: K – 2

For more ideas, see  Activity # 24 Nature’s Recyclers  in PLT’s  PreK-8 Environmental Education Activity Guide .

4. Modeling Pollution Uptake by Plants Using Celery

Pollution can also end up in food chains, including our own, which can have a negative on health and wellbeing. This activity is a great way to kick off a discussion about pollution and food chains. It involves creating a simple model that demonstrates how pollution can be drawn up into plants.

To do this activity, place a piece of celery in a jar or beaker of diluted food dye. Over time, the food dye moves up the celery, and there it remains. The food dye represents pollution, and the celery could represent any number of plants that are used for food. You can find specific instructions for this activity here .

Suitable for: K – 3 (NOTE – A knife is needed to cut the celery, so just be aware of that. Probably best if adults did that part).

For more ideas, see  Activity # 27 Every Tree for Itself  in PLT’s  PreK-8 Environmental Education Activity Guide .

5. Polluted Display Jars

This activity enables students to “see” pollution in the classroom — a great teaching or memory aid when discussing the topic. And it’s super easy too! In summary, students collect samples of air and water (even snow), put them in clear glass or plastic jars, and then manually “pollute” them.  

You can find some instructions and ideas here . But here are some quick suggestions regarding what could be added to your jars to pollute them: For your jar of air, you could drop a lit match into the jar, and quickly put the lid on, so that the smoke is caught in the jar. That will certainly give that nice clean air a brown/grey tinge! (Only adults should handle the matches.) For the jar of water, dirt and bits of plastic will suffice. Remember to have jars of clean water, air, and snow so students can compare the clean ones with the polluted ones. 

Suitable for: K – 5

For more ideas, see  Activity # 28 Air Plants  and Activity # 36 Pollution Search   in PLT’s  PreK-8 Environmental Education Activity Guide .

6. Sea Turtle Fate Game

From the moment they are born, various species of sea turtles have a tough time making it through to adulthood.  Although sea turtles die of natural causes or as the result of predator attacks, they also die as a result of human activity and pollution. This game allows students to explore the effects of humans on sea turtles, and the true scope of the problem.

You can find a detailed explanatory video here . The activity involves drawing plastic eggs out of a bowl of sand, with each plastic egg having a “fate” message inside. The message describes whether the figurative sea turtle in that egg survived or not, and if it didn’t survive, why not. Students then sort each ill-fated turtle egg into categories related to whether its death was as a result of man-made or natural causes.

Suitable for: Grades 2 – 5 (it could be used with younger students, depending on the make-up of your class. The themes may be a little too deep for some).

7. Watering Plants with “Acid Rain”

Acid rain is a significant threat to the environment and is caused by pollutants in the atmosphere mixing with rain as it falls. The topic of acid rain is something students may learn about in both science and geography. This activity allows students to create their own “acid rain” and to asses its effects. 

You can find detailed instructions here . In this experiment, students water three separate plants with either water, a little bit of acid, and a lot of acid. Use either vinegar or lemon juice as the acid. After leaving the plants in the sun to grow for a few days, watering them as they go, students will assess the effects of the acid on the plants. (You will need to be prepared to lose two plants. All for the sake of science of course!)

Suitable for: Grades 5 – 8 (depending on how in depth you go with the theory).

NOTE – You may like to have the children wear lab glasses when handling the lemon juice or vinegar. This can help avoid some stinging eyes, and of course, will make them feel like real little scientists!

8. Water Pollution Detection Experiment

This activity gives students an opportunity to get up close and personal with water “pollution” and explores some of the simple ways we can tell if pollution is present. This activity is excellent because it engages many senses.

The activity involves giving each student/group in your class a cup of clean water. You will then go around the class, adding a few drops of food coloring to each cup of water. The kids then stir the solution, making note of the fact that they can see the “pollution.” The same process is repeated, this time adding vinegar to the fresh water. This illustrates how sometimes we can smell “pollution”. The third time around, add salt and the students’ mix. This highlights that not all pollutants can be seen or smelled (once the salt has dissolved).

You can find detailed instructions for this “Playing Hide and Seek…with Pollution” activity here . There are also some additional questions, activities and suggested teaching strategies.

Suitable for: Grades 2 – 5 

For more ideas, see  Activity # 44 Water Wonders  in PLT’s  PreK-8 Environmental Education Activity Guide .

9. Climate Change Sensory Play

In lessons about pollution, teachers often discuss how it contributes to climate change, and this is a great activity to explore this concept using their sense of touch.  You can find instructions here .

Essentially the activity involves using frozen shaving cream (as snow/glaciers), blocks of ice, beads, and plastic animals to simulate a polar environment. Allow students to spend time playing on their own with everything in the environment. After some time, everything begins to melt. The activity dramatically demonstrates the impact of melting ice caps and glaciers. A discussion of pollution and climate change can follow. Be warned: this activity will require a bit of clean up!

Suitable for: Grades K – 3 

For more ideas, see  Activity # 84 The Global Climate  in PLT’s  PreK-8 Environmental Education Activity Guide .

Are you planning on trying any of these activities? What are some other ways you teach your students about pollution? Let us know in the comments!

Where and how do we download these activities, they look good. I am a facilitator for Wild B.C. and took the online PLT course.

Thank you for sharing! I teach AP Environmental Science to Junior and Senior level students in High School. We just did a lesson on Biomagnification during our pollution unit. I plan to use the celery activity as a demonstration/visual aid to help them SEE Bioaccumulation then review over Biomagnification. Next year I’ll do your celery demo before the activity.

P.S. I have been through the PLT workshop and appreciate your efforts.

Thank you for these. I have a 7year old who is doing a project on energy and pollution. Some great ideas to share with him!

Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants.

Pollution is the introduction of harmful materials into the environment . These harmful materials are called pollutants . Pollutants can be natural, such as volcanic ash . They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land. Many things that are useful to people produce pollution. Cars spew pollutants from their exhaust pipes. Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides —chemical poisons used to kill weeds and insects— seep into waterways and harm wildlife . All living things—from one-celled microbes to blue whales—depend on Earth ’s supply of air and water. When these resources are polluted, all forms of life are threatened. Pollution is a global problem. Although urban areas are usually more polluted than the countryside, pollution can spread to remote places where no people live. For example, pesticides and other chemicals have been found in the Antarctic ice sheet . In the middle of the northern Pacific Ocean, a huge collection of microscopic plastic particles forms what is known as the Great Pacific Garbage Patch . Air and water currents carry pollution. Ocean currents and migrating fish carry marine pollutants far and wide. Winds can pick up radioactive material accidentally released from a nuclear reactor and scatter it around the world. Smoke from a factory in one country drifts into another country. In the past, visitors to Big Bend National Park in the U.S. state of Texas could see 290 kilometers (180 miles) across the vast landscape . Now, coal-burning power plants in Texas and the neighboring state of Chihuahua, Mexico have spewed so much pollution into the air that visitors to Big Bend can sometimes see only 50 kilometers (30 miles). The three major types of pollution are air pollution , water pollution , and land pollution . Air Pollution Sometimes, air pollution is visible . A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible . Polluted air can be dangerous, even if the pollutants are invisible. It can make people’s eyes burn and make them have difficulty breathing. It can also increase the risk of lung cancer . Sometimes, air pollution kills quickly. In 1984, an accident at a pesticide plant in Bhopal, India, released a deadly gas into the air. At least 8,000 people died within days. Hundreds of thou sands more were permanently injured. Natural disasters can also cause air pollution to increase quickly. When volcanoes erupt , they eject volcanic ash and gases into the atmosphere . Volcanic ash can discolor the sky for months. After the eruption of the Indonesian volcano of Krakatoa in 1883, ash darkened the sky around the world. The dimmer sky caused fewer crops to be harvested as far away as Europe and North America. For years, meteorologists tracked what was known as the “equatorial smoke stream .” In fact, this smoke stream was a jet stream , a wind high in Earth’s atmosphere that Krakatoa’s air pollution made visible. Volcanic gases , such as sulfur dioxide , can kill nearby residents and make the soil infertile for years. Mount Vesuvius, a volcano in Italy, famously erupted in 79, killing hundreds of residents of the nearby towns of Pompeii and Herculaneum. Most victims of Vesuvius were not killed by lava or landslides caused by the eruption. They were choked, or asphyxiated , by deadly volcanic gases. In 1986, a toxic cloud developed over Lake Nyos, Cameroon. Lake Nyos sits in the crater of a volcano. Though the volcano did not erupt, it did eject volcanic gases into the lake. The heated gases passed through the water of the lake and collected as a cloud that descended the slopes of the volcano and into nearby valleys . As the toxic cloud moved across the landscape, it killed birds and other organisms in their natural habitat . This air pollution also killed thousands of cattle and as many as 1,700 people. Most air pollution is not natural, however. It comes from burning fossil fuels —coal, oil , and natural gas . When gasoline is burned to power cars and trucks, it produces carbon monoxide , a colorless, odorless gas. The gas is harmful in high concentrations , or amounts. City traffic produces highly concentrated carbon monoxide. Cars and factories produce other common pollutants, including nitrogen oxide , sulfur dioxide, and hydrocarbons . These chemicals react with sunlight to produce smog , a thick fog or haze of air pollution. The smog is so thick in Linfen, China, that people can seldom see the sun. Smog can be brown or grayish blue, depending on which pollutants are in it. Smog makes breathing difficult, especially for children and older adults. Some cities that suffer from extreme smog issue air pollution warnings. The government of Hong Kong, for example, will warn people not to go outside or engage in strenuous physical activity (such as running or swimming) when smog is very thick.

When air pollutants such as nitrogen oxide and sulfur dioxide mix with moisture, they change into acids . They then fall back to earth as acid rain . Wind often carries acid rain far from the pollution source. Pollutants produced by factories and power plants in Spain can fall as acid rain in Norway. Acid rain can kill all the trees in a forest . It can also devastate lakes, streams, and other waterways. When lakes become acidic, fish can’t survive . In Sweden, acid rain created thousands of “ dead lakes ,” where fish no longer live. Acid rain also wears away marble and other kinds of stone . It has erased the words on gravestones and damaged many historic buildings and monuments . The Taj Mahal , in Agra, India, was once gleaming white. Years of exposure to acid rain has left it pale. Governments have tried to prevent acid rain by limiting the amount of pollutants released into the air. In Europe and North America, they have had some success, but acid rain remains a major problem in the developing world , especially Asia. Greenhouse gases are another source of air pollution. Greenhouse gases such as carbon dioxide and methane occur naturally in the atmosphere. In fact, they are necessary for life on Earth. They absorb sunlight reflected from Earth, preventing it from escaping into space. By trapping heat in the atmosphere, they keep Earth warm enough for people to live. This is called the greenhouse effect . But human activities such as burning fossil fuels and destroying forests have increased the amount of greenhouse gases in the atmosphere. This has increased the greenhouse effect, and average temperatures across the globe are rising. The decade that began in the year 2000 was the warmest on record. This increase in worldwide average temperatures, caused in part by human activity, is called global warming . Global warming is causing ice sheets and glaciers to melt. The melting ice is causing sea levels to rise at a rate of two millimeters (0.09 inches) per year. The rising seas will eventually flood low-lying coastal regions . Entire nations, such as the islands of Maldives, are threatened by this climate change . Global warming also contributes to the phenomenon of ocean acidification . Ocean acidification is the process of ocean waters absorbing more carbon dioxide from the atmosphere. Fewer organisms can survive in warmer, less salty waters. The ocean food web is threatened as plants and animals such as coral fail to adapt to more acidic oceans. Scientists have predicted that global warming will cause an increase in severe storms . It will also cause more droughts in some regions and more flooding in others. The change in average temperatures is already shrinking some habitats, the regions where plants and animals naturally live. Polar bears hunt seals from sea ice in the Arctic. The melting ice is forcing polar bears to travel farther to find food , and their numbers are shrinking. People and governments can respond quickly and effectively to reduce air pollution. Chemicals called chlorofluorocarbons (CFCs) are a dangerous form of air pollution that governments worked to reduce in the 1980s and 1990s. CFCs are found in gases that cool refrigerators, in foam products, and in aerosol cans . CFCs damage the ozone layer , a region in Earth’s upper atmosphere. The ozone layer protects Earth by absorbing much of the sun’s harmful ultraviolet radiation . When people are exposed to more ultraviolet radiation, they are more likely to develop skin cancer, eye diseases, and other illnesses. In the 1980s, scientists noticed that the ozone layer over Antarctica was thinning. This is often called the “ ozone hole .” No one lives permanently in Antarctica. But Australia, the home of more than 22 million people, lies at the edge of the hole. In the 1990s, the Australian government began an effort to warn people of the dangers of too much sun. Many countries, including the United States, now severely limit the production of CFCs. Water Pollution Some polluted water looks muddy, smells bad, and has garbage floating in it. Some polluted water looks clean, but is filled with harmful chemicals you can’t see or smell. Polluted water is unsafe for drinking and swimming. Some people who drink polluted water are exposed to hazardous chemicals that may make them sick years later. Others consume bacteria and other tiny aquatic organisms that cause disease. The United Nations estimates that 4,000 children die every day from drinking dirty water. Sometimes, polluted water harms people indirectly. They get sick because the fish that live in polluted water are unsafe to eat. They have too many pollutants in their flesh. There are some natural sources of water pollution. Oil and natural gas, for example, can leak into oceans and lakes from natural underground sources. These sites are called petroleum seeps . The world’s largest petroleum seep is the Coal Oil Point Seep, off the coast of the U.S. state of California. The Coal Oil Point Seep releases so much oil that tar balls wash up on nearby beaches . Tar balls are small, sticky pieces of pollution that eventually decompose in the ocean.

Human activity also contributes to water pollution. Chemicals and oils from factories are sometimes dumped or seep into waterways. These chemicals are called runoff. Chemicals in runoff can create a toxic environment for aquatic life. Runoff can also help create a fertile environment for cyanobacteria , also called blue-green algae . Cyanobacteria reproduce rapidly, creating a harmful algal bloom (HAB) . Harmful algal blooms prevent organisms such as plants and fish from living in the ocean. They are associated with “ dead zones ” in the world’s lakes and rivers, places where little life exists below surface water. Mining and drilling can also contribute to water pollution. Acid mine drainage (AMD) is a major contributor to pollution of rivers and streams near coal mines . Acid helps miners remove coal from the surrounding rocks . The acid is washed into streams and rivers, where it reacts with rocks and sand. It releases chemical sulfur from the rocks and sand, creating a river rich in sulfuric acid . Sulfuric acid is toxic to plants, fish, and other aquatic organisms. Sulfuric acid is also toxic to people, making rivers polluted by AMD dangerous sources of water for drinking and hygiene . Oil spills are another source of water pollution. In April 2010, the Deepwater Horizon oil rig exploded in the Gulf of Mexico, causing oil to gush from the ocean floor. In the following months, hundreds of millions of gallons of oil spewed into the gulf waters. The spill produced large plumes of oil under the sea and an oil slick on the surface as large as 24,000 square kilometers (9,100 square miles). The oil slick coated wetlands in the U.S. states of Louisiana and Mississippi, killing marsh plants and aquatic organisms such as crabs and fish. Birds, such as pelicans , became coated in oil and were unable to fly or access food. More than two million animals died as a result of the Deepwater Horizon oil spill. Buried chemical waste can also pollute water supplies. For many years, people disposed of chemical wastes carelessly, not realizing its dangers. In the 1970s, people living in the Love Canal area in Niagara Falls, New York, suffered from extremely high rates of cancer and birth defects . It was discovered that a chemical waste dump had poisoned the area’s water. In 1978, 800 families living in Love Canal had to a bandon their homes. If not disposed of properly, radioactive waste from nuclear power plants can escape into the environment. Radioactive waste can harm living things and pollute the water. Sewage that has not been properly treated is a common source of water pollution. Many cities around the world have poor sewage systems and sewage treatment plants. Delhi, the capital of India, is home to more than 21 million people. More than half the sewage and other waste produced in the city are dumped into the Yamuna River. This pollution makes the river dangerous to use as a source of water for drinking or hygiene. It also reduces the river’s fishery , resulting in less food for the local community. A major source of water pollution is fertilizer used in agriculture . Fertilizer is material added to soil to make plants grow larger and faster. Fertilizers usually contain large amounts of the elements nitrogen and phosphorus , which help plants grow. Rainwater washes fertilizer into streams and lakes. There, the nitrogen and phosphorus cause cyanobacteria to form harmful algal blooms. Rain washes other pollutants into streams and lakes. It picks up animal waste from cattle ranches. Cars drip oil onto the street, and rain carries it into storm drains , which lead to waterways such as rivers and seas. Rain sometimes washes chemical pesticides off of plants and into streams. Pesticides can also seep into groundwater , the water beneath the surface of the Earth. Heat can pollute water. Power plants, for example, produce a huge amount of heat. Power plants are often located on rivers so they can use the water as a coolant . Cool water circulates through the plant, absorbing heat. The heated water is then returned to the river. Aquatic creatures are sensitive to changes in temperature. Some fish, for example, can only live in cold water. Warmer river temperatures prevent fish eggs from hatching. Warmer river water also contributes to harmful algal blooms. Another type of water pollution is simple garbage. The Citarum River in Indonesia, for example, has so much garbage floating in it that you cannot see the water. Floating trash makes the river difficult to fish in. Aquatic animals such as fish and turtles mistake trash, such as plastic bags, for food. Plastic bags and twine can kill many ocean creatures. Chemical pollutants in trash can also pollute the water, making it toxic for fish and people who use the river as a source of drinking water. The fish that are caught in a polluted river often have high levels of chemical toxins in their flesh. People absorb these toxins as they eat the fish. Garbage also fouls the ocean. Many plastic bottles and other pieces of trash are thrown overboard from boats. The wind blows trash out to sea. Ocean currents carry plastics and other floating trash to certain places on the globe, where it cannot escape. The largest of these areas, called the Great Pacific Garbage Patch, is in a remote part of the Pacific Ocean. According to some estimates, this garbage patch is the size of Texas. The trash is a threat to fish and seabirds, which mistake the plastic for food. Many of the plastics are covered with chemical pollutants. Land Pollution Many of the same pollutants that foul the water also harm the land. Mining sometimes leaves the soil contaminated with dangerous chemicals. Pesticides and fertilizers from agricultural fields are blown by the wind. They can harm plants, animals, and sometimes people. Some fruits and vegetables absorb the pesticides that help them grow. When people consume the fruits and vegetables, the pesticides enter their bodies. Some pesticides can cause cancer and other diseases. A pesticide called DDT (dichlorodiphenyltrichloroethane) was once commonly used to kill insects, especially mosquitoes. In many parts of the world, mosquitoes carry a disease called malaria , which kills a million people every year. Swiss chemist Paul Hermann Muller was awarded the Nobel Prize for his understanding of how DDT can control insects and other pests. DDT is responsible for reducing malaria in places such as Taiwan and Sri Lanka. In 1962, American biologist Rachel Carson wrote a book called Silent Spring , which discussed the dangers of DDT. She argued that it could contribute to cancer in humans. She also explained how it was destroying bird eggs, which caused the number of bald eagles, brown pelicans, and ospreys to drop. In 1972, the United States banned the use of DDT. Many other countries also banned it. But DDT didn’t disappear entirely. Today, many governments support the use of DDT because it remains the most effective way to combat malaria. Trash is another form of land pollution. Around the world, paper, cans, glass jars, plastic products, and junked cars and appliances mar the landscape. Litter makes it difficult for plants and other producers in the food web to create nutrients . Animals can die if they mistakenly eat plastic. Garbage often contains dangerous pollutants such as oils, chemicals, and ink. These pollutants can leech into the soil and harm plants, animals, and people. Inefficient garbage collection systems contribute to land pollution. Often, the garbage is picked up and brought to a dump, or landfill . Garbage is buried in landfills. Sometimes, communities produce so much garbage that their landfills are filling up. They are running out of places to dump their trash. A massive landfill near Quezon City, Philippines, was the site of a land pollution tragedy in 2000. Hundreds of people lived on the slopes of the Quezon City landfill. These people made their living from recycling and selling items found in the landfill. However, the landfill was not secure. Heavy rains caused a trash landslide, killing 218 people. Sometimes, landfills are not completely sealed off from the land around them. Pollutants from the landfill leak into the earth in which they are buried. Plants that grow in the earth may be contaminated, and the herbivores that eat the plants also become contaminated. So do the predators that consume the herbivores. This process, where a chemical builds up in each level of the food web, is called bioaccumulation . Pollutants leaked from landfills also leak into local groundwater supplies. There, the aquatic food web (from microscopic algae to fish to predators such as sharks or eagles) can suffer from bioaccumulation of toxic chemicals. Some communities do not have adequate garbage collection systems, and trash lines the side of roads. In other places, garbage washes up on beaches. Kamilo Beach, in the U.S. state of Hawai'i, is littered with plastic bags and bottles carried in by the tide . The trash is dangerous to ocean life and reduces economic activity in the area. Tourism is Hawai'i’s largest industry . Polluted beaches discourage tourists from investing in the area’s hotels, restaurants, and recreational activities. Some cities incinerate , or burn, their garbage. Incinerating trash gets rid of it, but it can release dangerous heavy metals and chemicals into the air. So while trash incinerators can help with the problem of land pollution, they sometimes add to the problem of air pollution. Reducing Pollution Around the world, people and governments are making efforts to combat pollution. Recycling, for instance, is becoming more common. In recycling, trash is processed so its useful materials can be used again. Glass, aluminum cans, and many types of plastic can be melted and reused . Paper can be broken down and turned into new paper. Recycling reduces the amount of garbage that ends up in landfills, incinerators, and waterways. Austria and Switzerland have the highest recycling rates. These nations recycle between 50 and 60 percent of their garbage. The United States recycles about 30 percent of its garbage. Governments can combat pollution by passing laws that limit the amount and types of chemicals factories and agribusinesses are allowed to use. The smoke from coal-burning power plants can be filtered. People and businesses that illegally dump pollutants into the land, water, and air can be fined for millions of dollars. Some government programs, such as the Superfund program in the United States, can force polluters to clean up the sites they polluted. International agreements can also reduce pollution. The Kyoto Protocol , a United Nations agreement to limit the emission of greenhouse gases, has been signed by 191 countries. The United States, the world’s second-largest producer of greenhouse gases, did not sign the agreement. Other countries, such as China, the world’s largest producer of greenhouse gases, have not met their goals. Still, many gains have been made. In 1969, the Cuyahoga River, in the U.S. state of Ohio, was so clogged with oil and trash that it caught on fire. The fire helped spur the Clean Water Act of 1972. This law limited what pollutants could be released into water and set standards for how clean water should be. Today, the Cuyahoga River is much cleaner. Fish have returned to regions of the river where they once could not survive. But even as some rivers are becoming cleaner, others are becoming more polluted. As countries around the world become wealthier, some forms of pollution increase. Countries with growing economies usually need more power plants, which produce more pollutants. Reducing pollution requires environmental, political, and economic leadership. Developed nations must work to reduce and recycle their materials, while developing nations must work to strengthen their economies without destroying the environment. Developed and developing countries must work together toward the common goal of protecting the environment for future use.

How Long Does It Last? Different materials decompose at different rates. How long does it take for these common types of trash to break down?

• Paper: 2-4 weeks
• Orange peel: 6 months
• Milk carton: 5 years
• Plastic bag: 15 years
• Tin can: 100 years
• Plastic bottle: 450 years
• Glass bottle: 500 years
• Styrofoam: Never

Indoor Air Pollution The air inside your house can be polluted. Air and carpet cleaners, insect sprays, and cigarettes are all sources of indoor air pollution.

Light Pollution Light pollution is the excess amount of light in the night sky. Light pollution, also called photopollution, is almost always found in urban areas. Light pollution can disrupt ecosystems by confusing the distinction between night and day. Nocturnal animals, those that are active at night, may venture out during the day, while diurnal animals, which are active during daylight hours, may remain active well into the night. Feeding and sleep patterns may be confused. Light pollution also indicates an excess use of energy. The dark-sky movement is a campaign by people to reduce light pollution. This would reduce energy use, allow ecosystems to function more normally, and allow scientists and stargazers to observe the atmosphere.

Noise Pollution Noise pollution is the constant presence of loud, disruptive noises in an area. Usually, noise pollution is caused by construction or nearby transportation facilities, such as airports. Noise pollution is unpleasant, and can be dangerous. Some songbirds, such as robins, are unable to communicate or find food in the presence of heavy noise pollution. The sound waves produced by some noise pollutants can disrupt the sonar used by marine animals to communicate or locate food.

Study shows pollution affects the growth and behavior of aquatic organisms

by University of Jyväskylä

Research at the University of Jyväskylä, Finland, reveals that size-based selection, as happens in fishing, may impact the stress tolerance of fish, which in turn has a significant impact on the condition and coping of fish in changing environments.

The study proved that long-term exposure to manganese sulfate (MnSO 4 ), which is a common aquatic pollutant from mining, hampers the growth and alters the behavior of zebra fish. The study is published in Ecology and Evolution .

As we know, fishing is focused on middle-sized and large individuals through lower limits and fishing equipment restrictions, which often favors a fast life-cycle in target species. JYU researchers found that zebra fish with different life-history traits react differently to chronic exposure to manganese sulfate (MnSO 4 ).

"In our research, we concentrated on two life-history types: fast-growing fish characterized by rapid juvenile growth, early maturation, and smaller size, versus slowly growing fish characterized by slower juvenile growth, later maturation and greater size," explains Academy Research Fellow Silva Uusi-Heikkilä from the University of Jyväskylä.

Considering fish life-history types in conservation

The findings show that MnSO 4 exposure slows down the growth of zebra fish and lowers their condition factor, which is an indicator of well-being. However, the scope of impacts varies by life-history types.

Fish with the fast life-history strategy were more sensitive to MnSO 4 , as they grew more slowly when exposed to high concentrations. In addition, they had a lower condition factor, and they ate less than their conspecifics with a slow life-history strategy.

"Our findings show that manganese sulfate may deteriorate the growth and stress coping of fish, and that variation in life-history traits may play a crucial role in modifying the stress tolerance of individuals," Uusi-Heikkilä says.

"This study underlines that it is important to take population life-history traits into account in environmental risk assessments and protection strategies and also to consider the combined effects of fishing and environmental factors on fish populations."

The study provides valuable information on how pollutants like manganese sulfate ending up in the aquatic environment can affect aquatic organisms in various ways based on their life-history strategies.

"These findings have significant effects when we wish to get insight into the viability and adaptability of fish populations in polluted habitats," Uusi-Heikkilä states.
