1. What was your maximum temperature (use your Data Chart, not the picture)?
2. What was your minimum temperature (use your Data Chart, not the picture)?
3. What is your range? If you had any penalties or gifts, include those in your total.
4. What materials did you use in your insulated bottle (type them in order from your first layer, second layer, and third layer.)?
5. Why did you choose the materials that you did?
6. What are some materials that you didn't choose?
7. Why didn't you choose them?
8. Explain any blips on your graph (if you have them). Why did it do that?
9. Is an insulator a good or a poor conductor of heat energy?
- Our maximum was 95.4 degrees.
- Our minimum was 70.9 degrees.
- Our range was 24.5 degrees.
- The materials we used were a plastic bag (touching the jar), a piece of thick felt (in the middle), and a piece of quilt (on the outside of the jar).
- We chose the plastic bag because we knew that plastic was a good insulator; we chose the thick felt because we thought that, because it was thick, it would keep the water warm; and we chose the quilt because quilts keep people warm, so we thought it would keep water warm, too.
- We didn't choose foam, aluminum foil, or cotton.
- We didn't choose foam because we had seen tests from the previous experiment (Insulated Bottles) that showed foam being a bad insulator; we didn't choose aluminum foil because we learned it was a good conductor (Conductors), and good conductors are bad insulators; and we didn't choose the cotton because we didn't think it would be a good insulator.
- On our graph, everything from about 7.5 minutes until the end of the experiment was a blip. I think it did this because of the way the bottle was being held, and possibly some movement of the bottle.
- An insulator is not a good conductor of heat energy.
