Using a toy race car kids create a visual model of the Doppler Effect.

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

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

This trick uses vertical and horizontal forces to help your child to push apart your hands apart, no matter how hard you try to keep them together!

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.

This project compares the strength of one, two, and three-ply toilet paper.

This science fair project idea explores if the length of the string that an object is suspended on has an effect on how fast or slow it swings.

In this activity, your child will learn about a style of gardening that uses moss, also called "kokedama."

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

Air invisible; it doesn't make sounds; you can't pick it up and throw it. So how do we know it exists? Help your second grade scientist figure it out.

What is a compound microscope? Kids find out by making one of their own in this cool science fair project.
