This flexible activity for preschoolers features jellybeans, counting, coloring, and the five senses.

This science fair project idea quantifies the effect of weather- in this case temperature and humidity- on musical instruments.

In this experiment, young ecologists will learn about a type of edge effect: how trees and plants at the edge of a forest can act as a weed filter.

Science fair project that models the subterranean movement of water, using Darcy's Law. How can this information be used in hazardous material spills?

Explore convex and concave objects and how they reflect light.

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

What does yeast eat? Sugar, of course. But yeast also has some powerful enemies in the form of antifungal agents! Kids test them out in this fun yeast lab.

Research currently available fuel sources, and fuel manufacturing and processing techniques. Propose an alternative fuel source.

Evaluate whether people can raise the temperature of their finger using the power of their thoughts.

Learn about the microclimate of your backyard by tracking rainfall, temperature, and observed weather with hand drawn charts and graphs.

In this "paper and pen" science fair experiment, students will research the difference between standard time and astronomical mean time.

Science fair project that demonstrates the process known as refraction, which allows glasses and contact lenses to help people with poor vision.
