Ever wondered how an avalanche works? Try this winter activity on for size. Simulated disasters help you understand the real thing.
What You'll Need:
Cardboard box (cut in half, corner to corner)
On a cold day, cut a cardboard box in half, corner to corner, creating a cardboard peak that will sit flat on the ground.
Wet the box and let it freeze, peak to the sky. Once it's frozen, wet it again to create a second, smoother layer of ice. Now let snow blanket the icy peak.
Will the snow slide off that steep sheet of ice? A soft bump will help you find out -- and simulate a real avalanche.
On the next page, you'll learn how to make your own compass to find out which way is north.
