Using Heat- Lots of Heat
Whew, it's getting hot in here! Just kidding, but really, today we conducted a couple of different experiments to test how heat travels and transfers to objects and the affects it has on objects it comes in contact with.
The first experiment we did was to test how heat causes things to expand. The metal sphere would pass back and forth through the ring before it was heated, but would not after it was heated. Its' pretty cool to see visually and doesn't take very long to heat it up! The second experiement we did was to see and feel how heat transfers to some materials better than others. We tested a metal spoon and a wooden clothes pin to see the difference. We could touch the wooden clothes pin, but not the spoon, because it was too hot!
