Heat Transfer

I chose the basic materials that were losted for the heat transfer lab. The wool I could not find and had to go to the store to find it. I picked up some silk while I was there so I could use both items later on in a static electricity lab. The aluminum foil worked well. I guess it does help to trap in the heat. The thermometer that came with the kit was not a very good one but when you look around the house and can't find one, it is as good as it gets. The lab was simple and worked well with no problems. I would like to use this lab to reach the open inquiry level. How did your work out? Are there any things you would add to the experiment or change?
