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

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

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.

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 these homemade shell fossils and introduce your child to the wonders of science!

Is our water polluted? Help your young scientist understand the importance of taking care of the environment with this simple experiment.

This plaster fossil activity is a fun supplement to preschool science. Use plaster to make imprints of your child's handprints, footprints and other objects!

Kids are sure to be entranced by the magic of the ocean when they create their very own ocean in a bottle.

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