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.

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

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 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!

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.

Here's a great activity that uses corks and toothpicks to create a fleet of floating boats. Which design makes for the most seaworthy vessel?

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.

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

Make a DIY golf putter and design your own golf putting course in this 2nd-3rd grade arts and crafts/game activity.

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!
