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.

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.
