Fill each paper cup with 1 1/4 cup of water
Place on an even surface in the freezer overnight.
Gather the two frozen "glaciers" in the paper cups, a heavy object, and 2 pans.
Place each "glacier" in a pan Then, place the havy object on top of one glacier.
Watch the puddling of water at the base of each "glacier" after 1 minute, after 2 minutes. What do you see?
Wait about another 10 minutes. What happened?
Keep watching. If you are able, video the activity. Does the object eventually fall? Why do you think it did?
Look at the top of the two "glaciers" once the object falls. What do you notice?
Once the heavy object falls, place it flat in the pan up against the "glacier", let sit.
After another 60 minutes, look at the "glaciers." What do you notice about the glacier with the heavy object up against it?
When the "glaciers" have been melting for 90 minutes, carefully remove them from the pan and measure the water in each pan, individually. Which pan had more water?
