1. What was the most surprising thing you learned about energy during this entire unit? Why was it surprising?
2. What was your favorite part of this energy unit? Why was it your favorite?
3. Where is energy found?
4. How would you define energy?
1. The most surprising thing for me was the by products. I thought that this was surprising because I did not know that energy could have by products.
2. My favorite part of the unit was the energy transfers station. It was my favorite part because we got to experiment with the objects.
3. Energy is found everywhere. Some examples are schools, playgrounds, houses, etc.
4. I would define energy saying that, energy is something that is everywhere and people use it everyday.
The butter on the wood did not fall.
The butter on the aluminum slid 2nd 7 seconds into the project.
The butter on the copper slid 1st 2 seconds into the project.
The butter on the brass slid 3rd 85 seconds into the project.
The butter on the plastic slid 4th 2640 seconds into the project.
I predict that brass will slide first because brass, copper will slide second, aluminum will slide third, plastic will slide fourth, and wood/bamboo last.
1. The heat energy transferred from the cup warmer to the water to the stick to the butter.
2. Both today's experiment and yesterday's experiment had heat energy transfer from water. The main differences were today the heat came from the cup warmer to the water and then to the stick and then to the butter. Yesterday the heat came from the warm water and transferred through the cup to the cold water.
3. My predictions were close. My first three were wrong, but my last one was correct.
4. The two best were copper and aluminum. The evidence was the the butter slid off the copper first and the aluminum second.
5.The two worst were plastic and bamboo. The butter stayed on the plastic for a long time and it never came off the bamboo.
6. I think that water is a great conductor. Because water can make energy or take away energy.
7. It matters because you would want to know what materials would get hot or not. We use conductors when we cook on the stove, to keep our lunches hot or cold or when we want things to stay hot or cold.
