What Did You Learn?
Which glass do you think has hot water in it?
How do you know that glass has hot water in it?
How do molecules move differently when they are hot compared to when they are cold?
Rub your hands together really quickly. Do you feel the heat you generated? Supersonic airplanes, like the SR-71 Blackbird, generate heat as they fly through the air. The Blackbird gets so hot that the molecules move faster and the airplane material expands. Because of this expansion, the Blackbird is actually 1 foot longer when it is flying!
