Check out this cool science project idea to learn about rocks and explore the cycles of formation, breakdown, and reformation of rocks in the Earth's crust.

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.

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

This clay "painting" activity encourages and supports creative development and critical thinking skills.

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.

This biodiversity project examines the biodiversity in your own backyard.

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