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.

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!

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

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

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

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.

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

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.
