The Thermal Layers of Oceans
How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...

How Can Freezing Make Something Warmer?
Crazy fact—freezing liquid actually gives off heat! Young scholars investigate the transfer of energy when liquids freeze using a chemical heat pack. The heat pack gives off heat as its liquid core freezes.
