Most people think back to 8th-grade science class with fond memories where play and the real world mixed into discoveries and fun, hands-on experiments. Middle school science experiments allow kids to play with objects and resources like food and electricity – but it’s science.

It’s like belonging to a community where discovery is inevitable. 8th Grade science topics for homeschooling or the classroom are building blocks and inspiration for high school STEM subjects.

What Are Some 8th Grade Science Topics?

Physical science, earth science, and life science are the three primary 8th-grade science topics. Laying the foundation for STEM subjects , 8th-grade science offers flexibility and initiative for homeschooling and school teachers.

Physical Sciences

Physical sciences, an overview of scientific principles and procedures, teach students about waves, forces, motion, energy, and atmospheres. The focus is on physics and chemistry concepts that create a clear understanding of energy, matter, and the physical universe. Physical sciences are ideal for experimenting with ideas, thinking critically, developing problem-solving skills, and abstract reasoning.

8th Grade science students learn about the wave model of light, analog, and digital information, the energy of waves, how to use wave impulses to send information, and the properties of waves.

Students explore and learn how to measure energy and the various forces and motion in the world, including electricity, thermal energy, magnetism, and electromagnetism.

Teachers introduce and teach students about the vastness of science related to the atmosphere. 8th Grade science students will learn about heat and temperature, atoms and elements, state changes and particle motion, chemical reactions, and substances and their properties.

Earth Sciences

Earth science lessons study Planet Earth but aren’t bound to Earth. To understand Earth’s relation to the rest of the universes, students learn and explore the Earth, outer space, and the impact of forces around and among them. Teachers teach students basics in oceanography, geology, meteorology, and astronomy.

Exploring planet Earth will engage children and develop an interest in this fantastic planet. Studying the Earth, its resources, and its environment will reveal mysteries about its natural resources, tectonic plates, volcanic eruptions, and the energy available on Earth.

An 8th-grade science student will be amazed at how the ocean affects the climate. They will learn about climate patterns, severe weather, air pressure, solar energy, and the Earth’s atmosphere.

outer space

8th Grade science students realize things about the Earth they can only learn by viewing it from outer space. Space teaches them how the Earth rotates, why the Earth has a tilted axis, gravity in the universe, the fascinating solar system, and the moon with its phases and eclipses.

Life Sciences

Life Sciences is the study of living organisms and life processes. They learn about the variety of life on Earth, from genes to ecosystems, and explore human biology, plants, and animals. Giving an example or allowing a fun activity with everyday resources helps a child comprehend key life sciences concepts needed for high school.

Studying genetics and cell science introduces students to genes, genetic mutations, genetic engineering, and human bodies. A student learns about health, controlling body systems, body systems interaction, survival, and reproduction,

Introduction to ecosystems shows a student what a healthy ecosystem is and why it is essential. They learn all the different kinds of life that are part of an ecosystem, from plants and fungi to animals and microorganisms.

Adaptions explore the history of Earth, human impact and population, heredity genes, and evolution, and artificial and natural selection.,

Where Does A Science Fair Fit In?

A science fair inspires students to explore and focus on STEM (science, techology, engineering, and math) related projects. An 8th-grade science fair project is a fun way to turn readily available materials and classroom science activities into a unique experience. A classic science experiment becomes a cool project involving the scientific method of data presentation in tables and graphs. It’s an opportunity to test your ideas and prove to family and friends science is educational and fun.

Students graduating from their 8th grade science class should be able to design and perform a scientific investigation. They can identify and ask the right questions and conduct the experiment to find the answer. An 8th grade science student can use technology as a tool to gather, analyze, compare, and interpret the data on the computer screen.

Science students learn to solve problems, think critically, interpret data, follow procedures, and have fun with hands-on science activities. They build the foundation for earth science, life science, and physical science, preparing them for high school STEM science.

  • Ph.D., Biomedical Sciences, University of Tennessee at Knoxville
  • B.A., Physics and Mathematics, Hastings College

8th grade science fair projects tend to involve the scientific method and designing an experiment and not making models or explaining processes. You'll be expected to present data in the form of tables and graphs. Typed reports and posters are the norm (sorry, no handwritten text). You should do the project yourself, rather than enlist heavy-duty help from a parent or older student. It's appropriate to cite references for any information that isn't common knowledge or that draws on the work of others.

Ideas for Chemistry Projects

  • Does air temperature affect how long soap bubbles last? Does relative humidity?
  • What ratio of vinegar to baking soda produces the best chemical volcano eruption?
  • What type of plastic wrap prevents evaporation the best?
  • What plastic wrap prevents oxidation the best?
  • Can a saturated solution of sodium chloride still dissolve Epsom salts?
  • If you shake up different kinds or brands of soft drinks (e.g., carbonated), will they all spew the same amount?
  • Do all dishwashing detergents produce the same amount of bubbles? Clean the same number of dishes?
  • How permanent are permanent markers? What solvents (e.g., water, alcohol, vinegar, detergent solution) will remove the ink? Do different brands/types of markers produce the same results?
  • Is laundry detergent as effective if you use less than the recommended amount? More?
  • Do all hairsprays hold equally well? Equally long? Does type of hair affect the results?
  • What effect do additives have on the crystals? You could add food coloring, flavorings, or other 'impurities'.
  • What steps can you take to maximize crystal size ? You can affect vibration, humidity, temperature, rate of evaporation, purity of your growth medium, and time allowed for crystal growth.
  • How does the pH of soil relate to the pH of the water around the soil? You can make your own pH paper , test the pH of the soil, add water, then test the pH of the water. Are the two values the same? If not, is there a relationship between them?

Ideas for Projects About Living Things

  • What effect does soap in water have on plants? Is the effect the same at very low soap concentrations as compared with high concentrations?
  • How much plant food is too much?
  • Are dogs (cats/fish/etc.) colorblind? If so, is the lack of color perception compensated by better light/dark vision?
  • What types of words do babies learn to speak first?
  • Are goldfish water chemicals really necessary or are they an unneeded expense?
  • Can you graft a tomato plant onto a potato plant?
  • Do plants react to the presence of other plants? music? different colored light?
  • Will chilling an onion before cutting it keep you from crying ?
  • Does catnip repel cockroaches better than DEET ?

  • How do different factors affect seed germination? Factors that you could test include the intensity, duration, or type of light, the temperature, the amount of water, the presence/absence of certain chemicals, or the presence/absence of soil. You can look at the percentage of seeds that germinate or the rate at which seeds germinate.
  • Is a seed affected by its size? Do different size seeds have different germination rates or percentages? Does seed size affect the growth rate or final size of a plant?
  • How does cold storage affect the germination of seeds? Factors you can control include the type of seeds, length of storage, temperature of storage, and other variable s, such as light and humidity.
  • What conditions affect the ripening of fruit? Look at ethylene and enclosing a fruit in a sealed bag, temperature, light, or nearness to other pieces or fruit.
  • How close does a plant have to be to a pesticide for it to work? What factors influence the effectiveness of a pesticide (rain? light? wind?)? How much can you dilute a pesticide while retaining its effectiveness? How effective are natural pest deterrents?

Ideas for Physical Projects

  • What paper airplane design flies the farthest? stays aloft the longest?
  • What soils best support structures, such as buildings?
  • What materials glow under black light ? Can you use the UV light to find invisible, possibly smelly, stains in your carpet or elsewhere in your house?

Science Fair Projects for 8th Graders

As kids reach the 8th grade, their exposure to science goes up a notch. Equipped with basic knowledge, they can begin to explore more complicated concepts and satisfy their curiosity for deeper answers to the ‘whys’ and ‘hows’ of the world. This can translate to better science fair projects, whether that’s a DIY experiment or a science kit . 

Examples of common sights during 8th-grade science fairs include testing hypotheses on the effects of music on plant growth, how the concept of the center of gravity allows almost anything to balance, studies on mammal organs, and how to make batteries powered by fruits or vegetables. Here’s a breakdown of some of these science fair projects for 8th graders:

Musical Plants

We’re taught that plants are living things–but how alive are they, really? A great way to test this is to observe how they grow under varying environments. Introduce different types of music to multiple plants and observe how their exposure to their respective genres affects their growth. Your kiddo might be surprised to see the contrast in the development between plants exposed to pop, classical, and heavy metal music, among others.

Center of Gravity

The center of gravity is an imaginary point in a body of matter that represents the average location of its weight. One of the most interesting concepts concerning the center of gravity is how it can be used to determine how almost any object can be balanced. 

Your 8th grader can have fun exploring this idea by finding the center of gravity of random objects, and then recording their findings to present during the science fair. You can help them document their attempts to find the balance of different things!

Organ Dissection

One of the most effective ways to teach kids about bodies is to expose them to animal anatomy through hands-on activities like dissection. Home Science Tools offers a variety of dissection kits, from mammals to fetal pigs to frogs. 

An 8th grader will enjoy exploring the anatomy of animals using these kits, and their learnings can make a great science project! For a bit more fun, they can play around with science project name suggestions related to their dissected animal of choice.

Fruit- or Veggie-Powered Batteries

Batteries work through a chemical reaction that occurs between two pieces of metal called ‘electrodes’ and a liquid or paste called an ‘electrolyte.’ Many fruits and vegetables, such as potatoes, contain enough moisture to work similarly as an electrolyte. 

To make your own battery, you’ll need some special tools and equipment, and Home Science Tools’ Veggie Power Battery Kit for Science Buddies has got you covered with the essentials–including reusable electronic components, oversized electrodes, and a quality multimeter.

List of 8th Grade Science Fair Ideas

Science fairs let students experiment independently.

Can You Define These Impossible Science Terms?

Eighth-grade science fairs are an opportunity for students to get really in-depth with an area of scientific inquiry they find personally fascinating. Choosing the right topic can be a challenge, as the entire project depends on whether the topic is viable for research and will create interesting results. When picking a topic, consider what you personally find inspiring about science and build an idea from there.

Biology, which is the study of life and living organisms, can be a fascinating area of scientific inquiry for eighth graders. Some eighth-grade appropriate biology science fair topics include, "How much light do plants need to survive?" "What conditions are ideal for growing mold?" "Where is the richest soil found?" "What effect do fertilizers have on dying plants?" and "Do some plants produce more oxygen than others?"

Chemistry is the study of matter and the changes it goes through. Chemistry is a good area of science for eighth graders interested in experimenting with making matter change through chemical processes. Some topic ideas for science fair projects could be "How quickly can you dissolve salt in water?" "How do you make water change from a gas to a solid?" "Can sea water be desalinated?" and "Which chemicals put out fire the most effectively?"

Physical Science

Physical science encompasses physics and and the physical world. Physical science projects are good for eighth-grade students interested in machines and how they work. Some project ideas could include "How do pulleys make lifting a weight easier?" "What compound machine is best suited to different tasks?" "Which surface is the best for pushing a weight on?" "What type of metal is the best for conducting heat?" and "Can paint help prevent rust?"

Behavioral Science

Behavioral science is the interesting world of studying why people act the way they do. Behavioral science projects are particularly well suited for eighth graders, as they can use their peers as test subjects. Some possible behavioral science project ideas are "How does music affect memory?" "What affects people's reflexes?" "How much can we trust memory?" "What is the ideal environment for learning?" and "Can people differentiate between different brands of food by taste?"

The Best 8th Grade Science Fair Projects

Rebecca Gray October 1, 2020 STEM Projects

8th Grade Science Fair Projects – Don’t make it harder than it has to be!

It’s happened. Your eighth-grader brought home an assignment that can strike fear into the hearts of parents everywhere.  It’s true. The science fair is upon us.  The teacher has given them a lengthy rubric outlining all the requirements and presentation methods their assignment must adhere to.  The scope of the project is enough to make your head spin if this isn’t something you’ve already done with them in 7th grade.  The hardest part for most middle-school students is selecting age-appropriate science experiments that can be completed independently.

Hark! Fear not brave parents, for choosing an 8th-grade science project doesn’t need to be scary or overly complicated. Your rookie scientist just needs to find a question (hypothesis) that they really want to answer. Being interested in the outcome (conclusion) of their own project is an important part of getting them to do the work willingly rather than begrudgingly.

Check out some of the best 8th-grade science fair projects we’ve found to get your budding researcher’s wheels moving! (And don’t forget your trusty lab notebook to record methods and observations!):

1. How Does Stress Affect Body Temperature?

  • Thermometer

A classic mercury thermometer.

How it’s done:

This project could illustrate why your student literally sweats that math test every week. Have your volunteers perform a timed math test or a series of difficult puzzles.  Take their temperature before and immediately after the high-stress activity, record, and compare! Did your volunteers stay cool under pressure? How  did stress affect their temperature regulation ?

2. Which Beverages Release the Most Gas?

  • Baking Soda
  • Heating Pad
  • Bottles with narrow necks

A glass of milk and a glass of juice sit on a table next to a spoon.

When is a balloon actually a belch?  In this project of course!  Pour equal amounts of different beverages into individual bottles and add vinegar (to act like our stomach acids).  Placing the bottles on a heating pad will speed up this “mock digestion”.  One of the properties of gas states that gases expand to fill their container.  Expanding gases will inflate the balloons that have been stretched over the opening of the bottle, visually illustrating  which beverage releases the most gas !

3. What Effects Do Carbonated Drinks Have on Meat?

  • 3 types of meat (i.e. steak, chicken, salmon)
  • 3 containers
  • 6 cans of carbonated soda

A small pile of cubes of raw meat on a cutting board.

Did you know soda has a similar pH level to the human stomach? So soda should be able to digest meat as our stomachs do, right?  To test this hypothesis, place each different meat into a container and cover it completely with soda.  Observe the meat over several days.  Record observations.  Students can even weigh the meat before/after the experiment to include quantitative data along with their visual observations. Read more about why  this science project  works the way it does!

4. Create an Optical Illusion With an Infinity Mirror

  • Cardboard box
  • Mirror (same shape as the container)
  • Mirrored window cling
  • LED Christmas lights
  • A sheet of plexiglass or acrylic
  • Cutting tool

Two bathroom mirrors make what appears to be a never ending reflection of each other, similar to the effects of an infinity mirror.

Mirror, mirror on the wall – Are you a mirror or a never-ending hall? Your student will create an optical illusion with some inexpensive and basic supplies.  Use adhesive to secure the mirror to the floor of the box.  LED bulbs are inserted through holes in the walls of the box.  The visual trickery lies in the mirrored window cling viewing window.  Check out this  optical illusion  in greater detail!

5. Can We Distill Saltwater With Solar Power?

  • 2 plastic containers
  • 25 mL graduated cylinder
  • 800 mL beaker
  • Modeling Clay
  • 2 5mL funnels
  • Flexible straws
  • Steel washers
  • Rubber bands
  • Plastic Wrap

Droplets of water that appear to be evaporation or condensation are gathered and sliding down a smooth surface.

When ocean water evaporates, the salt is left behind. Collect this desalinated water with a simple DIY contraption. Containers of saltwater placed in the sunshine will begin to evaporate.  Cling wrap will cover the containers to collect evaporation. Use the heavy washers on top of the cling wrap to guide droplets of evaporated water down a gentle slope into the funnel.  The funnel and straw will empty into a waiting cup.  Cover the cup so no freshwater evaporates!  Check out a detailed assembly of the  water distiller !

6. Are Our Fingerprints Inherited?

  • Paper Towel
  • Tracing paper
  • White paper
  • Magnifying glass
  • Volunteers – 15 pairs of siblings, 15 pairs of unrelated individuals

A dark fingerprint on white paper.

Volunteers can touch tracing paper that’s been heavily scribbled on with pencil.  Place the index finger onto the sticky side of a piece of tape. That piece of tape now holds a clear fingerprint!  Using the magnifying glass, compare the fingerprints of siblings and non-related volunteers and record. Are they the same pattern? Read up on  fingerprints  to feel like a real detective!

7. Owl Pellet Fossil Reconstruction

  • Owl Pellet (available online)
  • Clean paper
  • Tweezers, needles, and/or wooden probes to deconstruct pellet
  • Owl Pellet Bone Chart
  • Small papers to separate bones and waste between

An in-tact owl pellet lies on a wooden surface, with a second own pellet in the background.

Owl pellets (think cat hairball) hold evidence of an owl’s most recent meal. Gently use tweezers, needles, or wooden probes to separate the owl pellet into four quarters.  Carefully pick the quarters apart, and set aside the animal bones on a separate sheet of paper. Think of it like a treasure hunt – a really gross treasure hunt.  Use a  bone chart  to reconstruct and identify the animal found in the pellet.

8. How Does Color Affect Heating? A Look at Light Absorption

  • 6-8 identical glass jars
  • 6-8 pieces of colored construction paper
  • Timer or clock
  • Drill for making holes in jar lids

A circular array of multi-colored paper.

Wrap each jar with construction paper.  Fill each jar with equal amounts of room temperature water.  Take an initial temperature reading, and then another after each jar has been sitting beneath the heat source for an amount of time (i.e. – 30 minutes).  Record your observations, and decide if there is a particular color that absorbed more light/heat! Read about the  science behind this project  in depth.

9. Homemade Hand Warmers

  • Jelly crystals
  • Iron Fillings
  • Calcium Chloride
  • Zipper-Lock Bag

A woman wearing warm clothes appears to be blowing on her hands to warm them.

You may find yourself repeating  this project  for a cold night of trick-or-treating or winter caroling.  Fill the small cup with water and ¼ tsp. of the jelly crystals.  Allow time for water absorption.  Add iron fillings and Calcium Chloride to the bag.  Manipulate the bag to mix ingredients.  Feel the heat!  You can add numerical data to this experiment by taking the temperature of the polymer beads throughout the experiment.

10. What Makes a Diaper Absorb Moisture?

  • New baby diaper
  • Zipper-lock bag
  • Small plastic cup

This image shows the lower half of a baby wearing only a diaper, slightly covered by a baby blanket.

It’s probably been a while since you had diapers in your house if you’re helping your 8th grader with homework.  You can use scissors to open the diaper.  You’ll collect polymer powder from the diaper’s stuffing into a cup.  Pour water over and watch as the polymer gels.  You can increase the research level of  this project  by comparing diaper brands and measuring the water quantities each diaper can hold.

11. What Door Handle in the School Holds the Most Bacteria?

  • Bacteria growing kit (Petri dishes with agar)
  • Sterile cotton swabs

A blue gloved hand holds up a petri dish that is rife with bacteria and growth.

Try to talk your kid out of wearing gloves to school for the rest of the year after completing  this project .  Using sterile swabs, sample 5 dirty doorknobs at the middle school. Rub the swab in the petri dish, cover, label, and date. Get ready to be grossed out.  Observe the Petri dishes over the next few days and keep detailed records of the growth.  Which door handle hid the most bacteria?

12. Why Do We Need Tendons? Engineering a Bionic Hand

  • ¾ inch dowel rod
  • 1-inch X 4-inch pine plank
  • 5 bags of small screw eyes (eyelets)
  • 2 rolls of nylon string
  • Wide rubber bands
  • 1 open eyelet
  • White spray paint
  • ¾ inch sheetrock screws (x2)
  • Basic power tools used under close adult supervision (grinder, jig saw drill press)

A white robotic hand reaches out to touch the tip of the index finger of a genuine human hand over a yellow background.

This experiment will make your child feel like Tony Stark, and teach them a bit about human anatomy.  You’ll cut and grind dowel rods to make mock “bone segments”.  Eyelets are inserted into bone segments where “tendons” and “ligaments” (string) will attach.  Spray paint all the bone segments white, for an authentic skeleton look.  The pine plank makes up the palm/wrist area.  Assembling this bionic hand  will earn you a high five from your teacher.

13. Which Mouthwash is Most Effective at Killing Bacteria?

  • Multiple brands of mouthwash
  • Petri dishes with agar for growing bacteria
  • Sterile swabs

A young lady with her mouth open wide and her tongue sticking out.

We predict your child will better about dental hygiene after this science project.   Swab the inside of your student’s mouth a couple of hours after eating, and apply the sample to the petri dish. Use the mouthwash according to the label, rinse with water, then take a second sample with a new swab.  Be sure to label each dish carefully. Repeat for each mouthwash type and compare bacterial growth. Try not to be grossed out, and determine  which brand of mouthwash works the best!

14. Can Caffeine Make Us Faster Typists?

  • Caffeinated beverage
  • A decaffeinated beverage (soda or coffee)
  • Word Processing Program
  • Test Subjects

This is an image of a computer keyboard, a watch, a planner, and a cup of coffee, along with a pair of hands. The left hand on the keyboard, the right hand gripping the coffee.

Volunteers will type: “The quick brown fox jumped over the lazy dog.” as many times as possible in one minute after ingesting a non-caffeinated beverage. Repeat the timed typing exercise after a decaffeinated beverage. Keep your volunteers in the dark about which beverage is caffeinated!

Editor’s note:  Let us know how  this project  works out – We might need to install a new coffee machine in the office for faster blog posting!

15. Can we see sound?

  • Uncooked rice
  • Plastic wrap
  • Sound source (Speaker, Pots and Pans, etc)

Grains of white rice lay in a pile on a white surface.

When your teenager blasts their music, it can feel like they’re banging on your brain!  Show them  how those sound waves look .  This project lets us visually see the movement of grains of rice created by sound waves from loud noise nearby.  You can use pots and pans or a stereo speaker as a sound source.

16. Investigating the effects of external stimuli on carnivorous plant digestion

  • 3 Dionaea muscipula of similar size
  • Small crickets (available at any pet store)
  • 3 temperature controlled locations
  • Thermometers

A Venus Fly Trap plant with multiple "mouths".

Plants straight out of a science fiction movie  are enough to make any student interested in this project!  You’ll look at external stimuli effects on the digestion time of the Venus flytrap.  Plants are placed in locations where temperatures can be monitored and controlled.  “Feed” the plant a cricket.  After the plant snaps shut, monitor how many days each plant spends digesting the insects.  Do warmer temperatures speed up digestion?  Make sure your student doesn’t try to feed their little brother to the plant.

17. Determining the Iodide content of different types of salt.

  • Plastic cups
  • 100mL graduated cylinder
  • Distilled water
  • Laundry starch solution
  • Iodine antiseptic solution
  • Medicine dropper
  • 5 types of salt
  • Hydrogen peroxide solution

8th grade science research topics

Tell your eighth grader there’s no reason for them to be ‘salty’ about a little hard work.   This project  is inexpensive and has a short observation.  First, create a solution of distilled water, laundry starch, and iodine.  Stir and set aside.  Mix salt and distilled water and stir. Add 15mL of vinegar, then 15 mL of hydrogen peroxide.  Add 2.5 mL of the starch solution you set aside. Repeat these steps with each salt. What colors are you seeing?

18. What material blocks UV light most efficiently?

  • UV reactive beads (available at most craft stores or online)
  • Ultraviolet lightbulb (or a sunny day)
  • Sunglasses, UV protecting clothing,sunglasses, sunblock, umbrella

A multicolor digital recreation of a strand of DNA

Sparking an interest in forensic pathology could start with this  crazy cool project .  First, create a saline solution with distilled water and salt.  Swish it around in your mouth for thirty seconds.  Spit it back into the paper cup and pour a bit into the test tube.  You’ll add a couple drops of liquid dish soap, some isopropyl alcohol, and voila! A milky white thread of DNA appears suspended in the test tube, ready to be wound around a wooden skewer.  You can freeze it in a vial for indefinite preservation!

23. Which soil type is most fertile for seed growth?

  • 4-6 different soil types
  • Easy-to-grow-seeds like beans
  • Small pots or jars
  • Paper towels
  • Plastic bag

A garden trowel filled with dark soil is spilling some to the ground. Flowers can be seen in the background.

This project is simple and inexpensive  but may take a few weeks to track.  Start seeds in a ziplock bag between layers of damp paper towels.  Transfer seeds carefully to jars of soil.  Be sure to water them equally, and place them in a location where they have access to even amounts of sunlight.  Track and record plant height and appearance over several weeks and compare.

24. Create your own pH level test strips.

  • Food processor
  • Red cabbage
  • Pot and burner
  • Isopropyl Alcohol

A head of purple cabbage sliced in half.

Creating their own testing supplies  ups your scientist from rookie to novice! Add chopped red cabbage and boiling water to a food processor.  Give it a good whir, and then strain the mixture.  In a bowl, combine cabbage mixture and alcohol.  Dip the coffee filters into the solution and soak them.  Remove them to dry.  Cut dry filters into strips and store in a dry place for use in awesome future science projects!

25. Can simple plants protect landscapes from soil erosion?

  • 6 empty 2-liter bottles
  • 1 piece of plywood
  • Plant seedlings

In this photo, young hands are seen gluing two-liter bottles horizontally to a wooden plank. One of the two liters is already filled with soil

This project  shows your child how important vegetation is to keep the shape of our landscapes.  This is a great experiment if heavy rains are a part of your everyday landscape.  Create three different soil situations inside the two liters.  Pouring water through the two liters and into a waiting catch basin shows us how much soil erodes with water/rain, and how plants offer some protection from erosion.

26. Do breath mints actually cool your mouth?

  • Strong breath mints
  • 250 mL beaker
  • Bottled water

This image shows a desk surface with multiple items and a computer keyboard, as a hand reaches for an Altoid brand breath mint.
