Delight your budding scientist with this cool physics magic trick and teach her some basic physics concepts while you're at it!

Introduce your child to the world of motion and physics with a bit of marble play inspired by Sir Isaac Newton!

What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.

What is it about a Slinky that causes it to walk down the steps? This simple experiment is a perfect illustration of both gravity and momentum.

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

Get your sense of humor ready for this fun science experiment that demonstrates the fundamental physics of air pressure.

This homemade barometer allows your little scientist to contemplate and compare different air and weather conditions.

Help your second grade scientist explore the timely topic of wind speed using a version of the classic Beaufort Scale.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

Combine the science of physics with the fun of playing spy. Your young detective can make his own tiny looking glass. It's simple to make!

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

Help your child get a grasp on what it was like to build gigantic ancient structures with this easy engineering activity about science and physics.

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 classic children's game demonstrates how sound travels through air vs. through a solid.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

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