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

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

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.
