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

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

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

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

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!

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!

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

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

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.
