What do worms eat? Kids find out what kinds of rotting leaves and vegetables worms prefer in this cool compost science fair project.

Why does purple cheese look nasty? Because color plays a big part in how we perceive the taste of different foods. Are birds just like us in this respect?

Slime: It's oozy, it's goopy, and it's just plain fun! Learn how to make slime with this fun science fair project.

The goal of this fun science fair project idea is to microwave candy and investigate: do some colors of M&Ms melt faster than others?

This science fair project idea teaches that time always passes at the same rate and nothing we do in our daily life âreallyâ affects how fast it moves.

This classic children's game demonstrates how sound travels through air vs. through a solid.

This science fair project teaches students about wilting and browning of salad greens.
