While students understand the connections between speed of molecules and temperature, how can these ideas be connected to explaining a more complex process like condensation?
It was obvious for students to see that as the temperature of a hot plate increased, water began to evaporate and boil. We turned what we saw into a physical model (check out the video below). And then used this to explain how water that had evaporated into the air could condense on the outside of a cold cup above. Check out our models to explain this next week!
