Introduce your child to science with something they see everyday--their shadow!

This science project examines the history of earthquakes and what we can do to prevent future disasters.

This experiment investigates whether there are certain sounds that affect men and women differently

This science fair project idea produces sounds by creating vibrations using different objects.

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.

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

In this science fair experiment, students learn about the scientific principles behind Doppler ultrasound.

Learn how matter transmits sound with a simple, hands-on experiment using sand, water and air.

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 project students determine which instruments composers use to create birdsongs and birdcalls in classical music.

Learn how to make marbleized paper with simple everyday ingredients in this fun activity! Your child will learn about oil and water while doing this project.

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.

Learn with makes water molecules work with this fun and easy science activity!

Learn to solve a crime scene investigation using an important forensics tool: oblique lighting.

Find out the differences (if any) in the frequencies of voices produced from a computer, from a phone, and directly coming out of the voice box of a human.

Future whistleblowers can learn about product safety standards with this exercise in writing and researching.

Your third grader will delight in learning about sound waves as he observes the different sounds created by tapping on glasses with varying amounts of water.

Your child will learn science and make a fun new malleable toy with this balloon sandbag science experiment.

Experiment with buoyancy to learn how a submarine rises and sinks in this classic science experiment.

Check out this fun science fair project idea to learn about seismic waves and how fast they travel during an earthquake.

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

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

Would your child like to learn about a hidden world? All she needs to do is open her box of markers!

Make stunning pendulum waves and learn the math behind the patterns generated with this cool and easy science project.

Take a look at forensic science with your child. She'll learn how to take a shoe impression, just like the detectives do!

In this cool science fair project, kids apply basic algebra to learn how to make a PVC pipe instrument while exploring concepts like frequency and resonance.

In this activity, you'll not only make your own bouncy balls at home, but your child will also learn how polymers are made.

Your kid can learn about the process of making frozen yogurt and enjoy a homemade, flavorful dessert. Experiment with this fun, chilly food!

In this fun science fair project idea learn the difference between additive and subtractive color and why they are handled differently.
