This science fair project teaches about mold. Students will test different foods to see which grow mold the fastest.

Start your toy engines -- this is going to be a fast and friction-filled race!

For this science fair project, kids will learn how to make a lemon battery. They can conduct this classic experiment using readily available materials.

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

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

This is a quick, easy science fair project that conveys the idea of density to preschool and early elementary children.

In this science fair project, young children will become aware of and have the opportunity to experience the four basic tastes: sweet, sour, salty, and bitter.

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.

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?

Camouflage is one of the most important animal adaptations in the African savanna biome. Kids create their own camouflage with this fun science fair project.

In this science fair project, kids will be able to see where germs reside on their hands while gaining insight into the benefits of thorough hand washing.
