My prediction. Plastic is probably the worst conductor I think that wood is the second worst conductor and aluminum comes next and then copper and the best conductor is brass.(I think)
- The heat got transferred from the hot plate to the butter from going through the different sticks because the butter was attached to the sticks and the sticks were touching the the hot plate and the hot plate made heat energy and the heat energy traveled through the sticks into the butter.
- I got all of my predictions wrong because I thought that the butter on the metal sticks would melt first because I thought that metal was the best conductor and that it would let the heat energy travel through it faster and get to the butter and melt the butter.
- the two best materials were copper and aluminum because there butter slid off of the sticks first.
- The two worst conductors were wood and plastic because it took the longest for there butter to fall off.
- I think that water is a good conductor because I know that electricity goes through water easily so heat probably could go through it to.
- I think that it matters because if it was not a good conductor because
- Describe how the heat energy transferred from the hot plate to the butter.
- How did the results compare to your predictions.
- Which of the tested materials were the two best conductors? What is your evidence?
- Which of the tested materials were the two worst conductors? What is your evidence?
- Do you think water is a good or poor conductor? Why?
- Why do you think it matters which material is a good or bad conductor? How do we use conductors in our life?
