Let's see.. there were plastic bags, foil, paper, paper towels, and tissues to try to cover the ice.
Students put the ice in the shade underneath a cabinet.Books and paper were used as fans.
And a cold water bottle was used as insulation.
Here is our final chart. One group was touching their ice almost the entire time and their ice melted in 10 minutes. Another group put water on it. Opps! Their ice melted almost immediately. We discussed why this happened and what strategies worked.
