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

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

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

This slightly messy, but tons-of-fun tactile activity will cement the idea of the land and water as pictured on maps in your young learner's mind.

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.
