Make "fossils" with your child to hide in the sandbox or at the park or the beach, to help your child explore his archaeological side.

Use dirt and different colors of craft sand to make unique layers in a clear plastic cup to represent the layers of the Earth.

Can't make it to the beach? Bring the science of ocean waves home with this fun earth science-related craft.

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.
