Answer these questions here:
Describe how the heat energy transferred from the hot plate to the butter.
- The heat went through the rod and heated it up and then it melted the butter and caused it to slide off.
How did the results compare to your predictions?
- I was spot on for all the predictions which made me really happy they were all in order.
Which of the tested materials were the two best conductors? What is your evidence?
- The first one to slide off was the copper and the second one was the aluminum my evidence is that they were both metal and metal can get really hot.
Which of the tested materials were the two worst conductors? What is your evidence?
- The worst one was wood and the second was plastic my evidence is that they weren't metal so they didn't get as hot as the other ones.
Do you think water is a good or poor conductor? Why?
- A good conductor because it can get really hot really easily because it is a liquid.
Why do you think it matters which material is a good or bad conductor? How do we use conductors in our life?
In this activity we had 4 rods copper, wood, brass, aluminum and plastic. there was frozen butter on top of each rods then we stuck them in a jar on a hot plate in the jar was heated water. Then we recorded the data of which one slid off first and which rods were the hottest and coldest.
