The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

What's the difference between centripetal and centrifugal force? Students find out by seeing both in action as they conduct this experiment.

Show your kids the power of baking powder by conducting a simple experiment. Make four batches of cornbread, all identical except for one thing: baking powder!

In this cool science fair project, kids apply basic algebra to learn how to make a PVC pipe instrument while exploring concepts like frequency and resonance.
