I think that The best Conductors ( in order) will be copper, aluminum, and brass because metals get really hot when there near something hot. Wood and plastic do not do not really let heat energy pass threw, I think? I think plastic will melt first thow .
What happened with...
wood- This object never melted while the timer was on.
copper- Copper slid down Within 5 min of starting. Copper is the best conductor.
plastic- Plastic is the one in fourth. after about 35 min the butter finally slid off.
brass- The brass was in third place for its butter sliding down the stick. it is still a pretty good conductor of heat.
aluminum- This is the second best conductor for heat because the butter melted second.

Answer these questions here:
- 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?
Answers:
1. First the heat energy was coming coming of the plate and into the water and made the water hot which then the heat traveled up one of the objects to the butter witch then melted because of the heat.
2. I amazingly got my predictions right. I don't know how because it was a total guess.
3. Copper and aluminum were the the best conductors because the butter melted in about 5 min and the aluminum melted in about 12 min witch were the first two to melt the butter.
4.plastic and wood are the worst conductors because plastic melted in about 35 min and wood never melted in the whole hour.
5. I think that water is a pretty good conductor because water gets really hot when its heated.
6. We use conductors like water and metal to cook food to eat and hot water also is good for hot tubs.
