This science fair project idea provides evidence that air is everywhere and takes up space.

There are many benefits to bugs and insects. This science project shows how cockroaches, termites, and other critters benefit our planet.

Do you have your isopods straight? Learn about sow bug and pill bug behavior by building a terrarium to study them in!

Can you plant the insect-attracting borage plant to increase the amount of beneficial insects in your garden? Find out in this experiment!

Have you ever seen fruit decay? Find out if a fruit will rot faster if you open it versus leaving it untouched!

Show your child that the simplest ingredients (salt and water) can be used to illustrate the concept of density!

Study the life cycle of the common blowfly as it relates to forensic investigation. Record the first time you see flies, maggots, and eggs.

Teach your child how to make an all-natural, yellow-brown dye, using just walnut shells and water. This deep dye can be used on textiles, art, and wood.

Does the temperature of a magnet affect its strength? Learn about the relationship between magnets and temperature with this cool physics science fair project.

This simple "how to make a water wheel" activity makes physics come alive for your child by demonstrating how different kinds of energy work.

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

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

The purpose of this science fair project is to determine which conditions and materials quicken the composting process to make the best compost.
