This biodiversity project examines the biodiversity in your own backyard.

Start your toy engines -- this is going to be a fast and friction-filled race!

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

Science fair project that examines how winter storms form and the relationship between temperature, moisture and snow.

Uh-oh! Is that a pill sitting on the counter or a piece of candy?

What's the science behind those out-of-sight roots? Find out if you can trick roots into growing in different directions.

Science fair project which determines whether people are more likely to follow rules if they are easy to understand.

This science fair project idea explores how much force is needed to move a lever at different distances from the fulcrum.

Check out this cool science project idea to learn about rocks and explore the cycles of formation, breakdown, and reformation of rocks in the Earth's crust.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

In this cool science fair project idea, kids conduct the ruler drop test on volunteers to determine whether reaction time can be improved with practice.
