What is a barycenter? Kids learn how gravity and mass influence the orbit of binary systems like planets and moons or stars and planets in this cool experiment.

Science fair project that determines what neurons are, what they do and compiles this vital information in an illustrated book.

Let your kid experiment with textures among fabric and other materials that are smooth, rough, soft, or slippery—and then they'll make a texture book!

Learn about the layers of the Earth and make a model! Create a earth layer book, cake, or clay diagram.

Science fair project that builds a magnetometer and demonstrate its uses.

In this free science fair project, build a star clock and learn how to tell time on a clear night by observing the big dipper!

Learn about savanna flora and fauna in this science project! Take a look at characteristics of tropical grassland plants and animals that help them survive.

The goal of this science fair project is to identify the galactic center of the milky way using globular clusters, as found through Google Earth.
