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.

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

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!

Kids construct a single fixed pulley system to learn how pulleys can make work easier in this cool physics and engineering science fair project idea.

In this project students experiment with making music using only glasses of water.

This science fair project idea determines if the size of the parachute will change the rate at which an object falls.

In this simple circular motion experiment, you'll observe tangential velocity and learn about how acceleration and centripetal force affect an object.

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 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.

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

This science fair project idea investigates if webbed feet help a duck (and others) swim.

This project tests the hypothesis that dark colors absorb more heat than light colors.

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.

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

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.

In this science project, the center of gravity is explored.

In this project, waves of vibrations are experimented with using water in glasses.

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

This science fair project idea investigates whether air has mass and weight.
