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.

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

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!

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.

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

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.

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.

Little scientists will make inferences about hearing loss, pitch, and frequency in this great science fair idea that puts the human ear to the test.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

Examine which metal conducts more heat by boiling water in 3 pans made of aluminum, copper, and stainless steel.

Science fair project idea examines validity of mood ring predictions. Analyze accuracy of results, consider the impact of temperature

Test whether plants can grow without sunlight and water.

In this science experiment, do tensile strength test on fishing line, a strand of hair, a rubber band, and any other materials you're curious about!

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

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

Have your kid determine if a goldfish can be conditioned to expect food the same way Pavlov's dogs did with this fascinating science fair project.

This science fair project idea examines which type of insulation holds in the most heat.

Saturn is the ringed planet in our solar system, a gas giant with rings made of ice and dust. Let's make a cool scale model with an old CD and some glitter!

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

Discover how and which salt melts ice the quickest.

Take a dive into the candy jar with this yummy science experiment.

Encourage a group of third graders to play this fun game of Whistle Hide-and-Seek as a warm-up to get them prepared for finding a "lost" camper.
