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.

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!

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!

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

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

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