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.

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?

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 idea produces varying pitches of sound.

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

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

This project examines whether playing music during class helps students learn or if it distracts students from learning.

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

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.

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

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

This biodiversity project examines the biodiversity in your own backyard.

What's the difference between a microwave and an oven? Use mashed potatoes to explore which kitchen appliance does a better job at keeping food warm.
