1. Describe how the heat energy transferred from the hot plate to the butter.
2. How did the results compare to your predictions.
3. Which of the tested materials were the two best conductors? What is your evidence?
4. Which of the tested materials were the two worst conductors? What is your evidence?
5. Do you think water is a good or poor conductor? Why?
6. Why do you think it matters which material is a good or bad conductor? How do we use conductors in our life?
1.BY THE CONDUCTERS OF COARSE!!! The heat from the pad go's into the jar of water making it hot. While most of the hot air stays in the water, only a few travel on the side of the conducters and to the butter. but when there is enough hot air in the butter it starts mealting. making it slippery enough so the hole pack can go down.
2. Well copper went first which was easy to know because Copper is made out of metal and metal gets lots of heat pretty fast.
3. Copper and Alumina were the best because they slid down first. My evidence is in the conducters. They were made of metal and metal get heat fast.
4. The plastic and the wood were the worst because they slid down last. My evidence is that they weren't shiny and smooth and cold. they where rufe and warm and wasen't that shiny.
