How good are humans at sound localization? Kids can try this cool science fair project idea to see how good their friends are at judging sound direction.

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

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

What causes sound? Here's a simple science experiment that adds a visual element to the science of sound to help kids better understand this tricky concept.

In this activity, you'll send your kindergartener on a scavenger hunt to find sounds and create a sound recording. Here's how!

Let your young scientist explore a brave new world of sound with an experiment that just requires a handful of common household items.

This science fair project idea produces varying pitches of sound.

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?

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

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.

Explore how sound waves are reflected and absorbed by producing echoes. Analyze which locations produce echoes.

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

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

Find out whether we can create motion in a dish and as a result, create a wonderful and colorful show.

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

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.

The project determines which laundry detergent is best for cleaning clothes.

Water can go from solid to liquid to gas...but how does popcorn go from kernel to snack? Invite your first grade scientist to find out.

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.

In this science project, baking powder and vinegar are used to simulate the action of a fire extinguisher.

This craft is an excellent way to learn about African-American history, and it also provides fine motor practice.

With this hands-on activity, you'll show how fall colors are hidden in the leaf all year long!

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.

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

These flying potato poppers make a cool sound, create a celebratory mood, and they can teach your child about the power of air pressure.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot move in a pattern related to the sound and rhythm of music.

In this activity your child will make a coiling snake out of simple household materials, and also find out why they coil.

What's the science behind those out-of-sight roots? Find out if you can trick roots into growing in different directions.

Did you know a mouse eats almost fifty times as much as a cow? Find out how and test out the strange science with your friends!

This science fair project idea measures out the sugar of various foods and find out whether people can correctly determine how much sugar is in common foods.
