What is the Best Insulator: Air, Styrofoam, Foil, or Cotton?

Abstract:

That heat flows from hot to cold is an unfortunate truth of life. People have put a lot of effort into stopping this fact, however all they have been able to do is slow the process. Working in groups of three to four, students will investigate the properties of insulators in attempts to keep a cup of water from freezing, and once it is frozen, to keep it from melting.
