By evening, it is nicely frozen and ready to be eaten. Besides being delicious, it also offers a great lesson on the science of freezing. To try this, you will need:

A Cool Change

This time, we are going to look into the sciences of chemistry and energy. It may seem strange to be looking into two different areas of science, but it is not unusual for the areas of science to overlap.
