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

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

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