In this experiment I tested four items as insulators; aluminum foil, house insulation, a cloth ovenpad, and a silicone oven pad. because of the dificulty I had in securing some of my test items to the mug, I found my results to be inconclusive. I did notice that heat was being transfered by conduction as the heat from the water in the mugs rose up through my testing substanse and I could feel the heat above the mugs.
One spin that I think would be interesting to test would be to change the material of the mug instead of the of the enclosure material. One could test styrofom, stainless steel, porcelin, and double insulated plastic mugs toped with aluminium for ease to see which mug was a better insulator.
I think to make this fun and engaging for the students, we could one day examine their lunch bags and see what they are bringing in for lunch. (I still have about 9 students who bring lunch from home.) If no one is bringing in hot food - we can discuss why. Maybe they can't find an insulator that works well for them? Then we could discuss what they would bring in if they could. I picture that we could end up testing bagel bites, pizza rolls, mini corn dogs, etc. in different types of insulators. Of course we would have to chose the variable . . . either the type of food or the typr of material, but the students could determine that.
