What you need:

Sand table or container with sand
Varity of objects such as a rock, a golf ball, a tennis ball, a ping-pong ball, a bead, a marble, etc.
Learning Goals and Standards:
What you do:
Show children some pictures of the moon. Point to the craters on the moon. Explain that these craters were formed by collisions from asteroids, comets and meteorites
Fill a sand table or a container with sand. Provide a varity of objects, such as a rock, a golf ball, a tennis ball, a ping-pong ball, a bead, etc. Invite children to drop the different objects in the sand. Let children observe the craters each object makes. Ask questions like, "Which object made the deepest crater? Which object made the smallest crater?" Let children discover the differences in size and weight of each object and the craters they create. Let them explore what happens if they drop the objects from different heights.
