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

This science fair project idea explores the relationship between oil and water in terms of density as well as hydrophilic/hydrophobic compounds.

Students pit the heat capacity of water against the heat capacity of oil while looking at the effects of dipole rotation in this cool science fair project idea.

Get your hands on a concoction that breaks the rules about what's a solid and what's a liquid.

Your kid can learn about the process of making frozen yogurt and enjoy a homemade, flavorful dessert. Experiment with this fun, chilly food!

This science fair project idea produces varying pitches of sound.

It's food. It's Thanksgiving tradition. And guess what: Cranberry Sauce is also science! Try our simple recipe/experiment.

Show your fifth grade scientist how to create a siphon using two buckets, plastic tubing, and water. Watch her astonishment as the water travels uphill!

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