Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures?

From the Physics 2000 site, this page exemplifies their usual superb discussion of the concepts of heat, temperature, and absolute zero. Using an entertaining series of cartoon characters, the page gives a very understandable discussion...

Another awesome page from the Physics 2000 site. Entertaining, interactive, educational, understandable. Explains the meaning of temperature and absolute zero. Discusses the temperature scales. Requires Java.

Discusses the methods the human body uses to regulate body temperature. Includes links to the four external heat transfer mechanisms (radiation, conduction, convection, and evaporation of perspiration).

When you are craving an ice cold drink of soda, the last thing you want is to be stuck with a bunch of soda cans at room temperature. This fun science experiment sends you on a discovery to find the fastest way to cool soda with...
