| Cooling by Boiling |
Water in a vacuum jar boils even though it is below room temperature. As the pumping proceeds, the water cools. | |

| Cold Sweat |
Evaporating sweat removes thermal energy from the body. This is simulated by placing a thermometer in paper towels soaked with ethanol and observing the temperature of the thermometer over time. | |

| Rock the Boat (new) |
A person sits in a boat on a pond holding a rock. If she throws the rock in the water, does the level of the pond go up, stay the same, or drop? | |
