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 "fossils" with your child to hide in the sandbox or at the park or the beach, to help your child explore his archaeological side.
