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

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!

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

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

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!
