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

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.

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.

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

This science fair project idea explores whether talking to a plant will help it grow.

Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.

This science fair project idea investigates the difference in reaction times between boys and girls.

What keeps a an item cooler, polymer crystals or ice? Find out in this cool science experiment!

This biodiversity project examines the biodiversity in your own backyard.

Collect meteorite dust with a magnet in your very own backyard! The objective of this science fair project is to gather meteorite dust to study outer space.

In this science project, learn about water transport in plants and make a beautiful dyed floral arrangement with cohesion, adhesion, and xylem tubes!

This science fair project idea determines what household items are good conductors of electricity.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

Can a toy car determine the strength of a magnet? In this cool magnet science fair project, young scientists will learn how to measure the strength of a magnet.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.
