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.

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

Is our water polluted? Help your young scientist understand the importance of taking care of the environment with this simple experiment.

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

Kids are sure to be entranced by the magic of the ocean when they create their very own ocean in a bottle.

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 plaster fossil activity is a fun supplement to preschool science. Use plaster to make imprints of your child's handprints, footprints and other objects!

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