In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

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!

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.
