Science Buddies: Just Keep Cool How Evaporation Affects Heating and Cooling
When we get hot, we sweat. The physiological role of sweat is to cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes, using what are referred to as...

Science Buddies: Keep Your Candy Cool With the Power of Evaporation!
Did you know that your body has a built-in cooler? And it might not be what you think. Sweat is produced when you are hot, but its purpose is actually to cool your body as the water in it evaporates from your skin. In this science fair...
