I think that the butter will in this order
1. The heat energy goes through the rods. The reason this happens is because they're conductors.
2. The main connections experiments used heat and energy probes. The main differences are are in yesterdays experiment we used hot and cold water and in today's we're using different rods and butter.
3.I predicted they would melt in the exact order.
4. Copper and aluminum were the best conductors. My evidence is that they were the first two that the butter melted on.
5. Plastic and bamboo were the two worst conductors. My evidence is that they were they last two that the butter melted on. It took about an hour for them both to melt.
6. I think water is a poor conductor of heat because it can be hot but not melt anything. I know this because whenever I take a shower I use warm water but it doesn't melt things in the shower.
7. If you want to have something that heat travels through really fast, you want a good conductor. If you want to keep something hot, you want a poor conductor. We use conductors in our houses.
