Do you think you can blow down a sand castle with a mighty wind? Find out which material stands up best to erosion in this erosion experiment.

Find out whether a longer airplane will fly farther or a wider paper airplane.

Kids will explore the corrosiveness of soda in this cool science fair project by leaving pennies submerged in soda overnight.

This easy and inexpensive paper towel science project introduces kids to important physical concepts like cohesion, adhesion, and capillarity.

This science fair project idea investigates emulsifiers that allow oil and vinegar to mix.

In this cool science experiment, learn about magnetism and poles, and test magnet strength to find out if two magnets are twice as strong as one.

These science fair experiments demonstrate the chemistry of rust and the oxidation process.

This project determines whether Styrofoam, paper, or plastic cups are best for preventing ice from melting.

In this cool engineering science fair project, kids learn how to build Hero's engine: an enlightening example of Newton's third law.

With this cool floating rocks project, your child will get some hands-on experience with buoyancy and learn why certain rocks like pumice are able to float.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

Kids will make a beautiful rainbow in a jar and learn what enables different types of liquids to remain distinct in separate layers.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

How does a flashlight work? Kids will make a complete circuit and explore how voltage contributes to brightness with this science fair project idea.

Understanding absorption means understanding why certain fibers and materials can absorb water! Kids will see absorption in action in this simple project.

Why doesn't the ocean freeze? Students answer this question by simulating the chemical composition and temperature of arctic waters in their own home.

The objective of this science fair project is to observe the differences in heat absorption for darker colors vs. lighter colors.

Do hand soaps and sanitizers prevent the growth of bread mold? If so, why? Kids will find out with this fun and informative science fair project idea.

How does a compass work? What's a magnetic field? Kids will build their own compass at home to find the answers in this great science fair project idea.

The objective of this science project was to build a model of a volcano and observe reaction between different substances, including baking soda and vinegar.

How can we describe the relationship of magnetic field strength vs. distance? Kids will find out with this free science fair project idea.

How powerful is the reaction between baking soda and vinegar? Find out here!

Kids will learn some cool stuff about chemical reactions by determining what happens when you mix different concentrations of hydrogen peroxide and yeast.

The goal of this fun science fair project idea is to microwave candy and investigate: do some colors of M&Ms melt faster than others?

How does smell affect taste? Ready your taste buds--in this project, you'll gather some test subjects and do a taste test to see how much smell affects taste.

While your cells are much too small to see without a microscope, you can create the look of a cell in your very own home with just an egg and vinegar!

Dinosaurs were huge creatures that left behind huge footprints that lasted for millions of years. In this science fair project, kids learn how dinosaur tracks were left behind!

Is it magic? No...it's the amazing, gravity-defying capillary action experiment! Kids will love this dramatic and enlightening science fair project.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.
