Glacier: Massive sheet of moving ice. Glaciers were present in Ohio during the Ice Age or Pleistocene.
Glacial till: Materials such as rocks and dirt deposited by the melting of a glacier.
1. Crumble cookies and place in bowl. The crumbled cookies represent the glacial till.
2. Put two large scoops of the ice cream on top of the cookies. A glacier begins as clean snow. However, as a glacier travels, it picks up dirt and rocks from the ground and becomes "dirty". The ice cream with the chocolate swirls represents the dirty glacier.
3. Place a plastic lunch bag over your hand, then slowly push down to "shmoosh" the ice cream so that it oozes. Notice that the cookies stick to the ice cream. A glacier moves much in the same manner. As more and more ice and snow fall on the glacier, the weight causes it to ooze, pushing the dirt in all directions.
4. To see how glaciers move (or ooze), warm up the marshmallow syrup or add a little hot water to make the syrup thinner. Then pour the syrup over the ice cream glacier.
EAT THE GLACIER AND ENJOY!!
