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.

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

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

Test whether plants can grow without sunlight and water.

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

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