Demonstrating of heat changes is done on the overhead projector by
illuminating the red fluid in a nonmercury thermometer using a simple and
inexpensive apparatus. The setup, which consists of an alcohol
thermometer inserted in a 50-mL plastic tissue culture dish, is placed on
a transparency slide marked with divisions that match the readings on the
thermometer. Demonstrations that provide dramatic heat changes are
described, including chemical reactions , dissolving of solutes and
simulation of flameless ration heaters and commercial hot and cold packs.
Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
