This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

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!

Stir up some enthusiasm for experimentation with this candy-cracking science experiment!

Take to the air with science by experimenting with helicopter seeds right in your own backyard!

Turn the common pastime of constructing paper airplanes into a lesson on the physics of aerodynamics and flight with this fun science activity.

This science fair project idea experiments with spinning color wheels and optical illusions.
