Heat Transfer Lesson

For this lesson, I decided to use a cloth, paper towel, saran wrap and tissues.  I wanted to use tin foil but of course we were out of tin foil.  The saran wrap was the most effective insulator.  In the future I want to compare the tin foil to the saran wrap to see which one is the better insulator of heat. For my students, I would like to ask them to think about how they keep things warm or cool in their own home.  I would like them to base their prediction on this and bring in the materials from home for them to test.  Perhaps I could make groups based on the students who bring in the same materials and then we could test and compare as a whole class.  I would like to have a test to see which size container keeps the water the warmest like in the article we read this week with the porridge.  I think that is something that students do not realize and would be beneficial for their understanding not just for class but in life as well.
