Conductors of Heat!

Questions:

1. How did heat energy transfer to the butter in this experiment?
2. What connections can you make between this experiment and yesterday's experiment?  "Both today's experiment and yesterday's experiment...  The main differences were..."
3. How did your results compare to your predictions?
4. Which of the tested materials were the two best conductors?  What is your evidence?
5. Which of the tested materials were the two worst conductors?  What is your evidence?
6. Do you think water is a good or poor conductor?  Why?  Can you think of any evidence to support your answer?
7. Why do you think it matters which material is a good or bad conductor?  How do we use conductors in our life?
   

Predictions:
1. I think that the butter were slide in the following order...aluminum (shiny metal)...copper (copper brown)...brass (gold)...plastic (white)...bamboo.
Answers:
1. The heat plate went through the cup and into the sticks and all the way to the butter which put all the heat inside of the butter.
2. Some connections with today's experiment and last times experiment was that they both used a bit of heat but last times experiment used some cold water but today's did not.
3. They compared to my predictions because I was wrong on the first one. I thought that the aluminum would be first.
4. The two best conductors were copper and aluminum. My evidence for that was because those both conductors were the quickest to melt the butter. The copper melted in about 10 seconds and the aluminum melted in about 13 seconds.
5. The two worst conductors were the bamboo and the plastic. My evidence for that was that it took FOREVER for the butter to finally melt.
6. I think water in a very good conductor because I remember doing an experiment last year about that and I saw that water was a good conductor.
7. It matters which conductor is a good or bad material because what if we need to know which is good or bad and we don't know? What if we need it right now but we can't check it. We use conductors in our life like when we cook, we use a frying pan as a conductor.
