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.

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.

Make over an old shirt that's destined for the thrift shop with this heart cut-out craft for Valentine's Day.

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

Here's a fun activity to show your child how to use prefixes and root words to "root out" the meaning of a word!

Stay active over summer vacation with this fun take on the old favorite Red Rover!

This activity teaches your third grader how to make a paper cut-out still life, in true Matisse-style.

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.

Filling out forms can be a great learning experience for kids. Here's how to give your child some FORMal training.

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

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.

Use a basic tape recorder and some favorite books to help your first grader read smoothly--and make someone's day in the process!

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

Teach your fifth grader the ancient Japanese art of origami with this incredible origami balloon that uses just one piece of paper!

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

Challenge your fourth grader to try to recreate the geography of her state using just flour, salt, and water.

Work on homophones, words that sound the same, and spelling with this imaginative activity!

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.

Okay, engaging in a graphing activity may sound ho-hum, but if you use fun data, it changes the picture entirely.
