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

In this fun activity, kids practice measurement and boost fine motor skills as they learn all about how fossils form and even make a few of their own!

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.

It's a rare kid who doesn't like a sandbox. Next time you're out digging, build in some earth science, too.

With some cookie dough and ordinary household objects, let your kindergartener explore how fossil imprints are made.
