Ingredients you will need:
    two rectangular pieces of cardboard
    hole puncher
    tape
    string
    cookie sheet
    dirt ( enough to cover the two cardboard pieces)
 

    Use the hole puncher to punch out two holes on one side of each piece of cardboard. Then put the string through the holes. Tie a knot using the ends of the string for both pieces of cardboard. Tape the cardboard pieces together but lay them so that the ends are not touching. Place the cardboard pieces on the cookie sheet. Put some dirt over top of the pieces. Make sure the dirt is covering both pieces completely. (It is better to do this outside.) Pull on the strings outward and watch the dirt as it simulates an earthquake.
