What is Why Antarctica about?

The document discusses how Weddell seals are able to live in Antarctica where the water is very cold. It explains that some water in Antarctica remains unfrozen due to high salt content, which lowers the freezing point. The salt levels are high because glaciers that form leave salt behind in the ocean water. An experiment is described where students add varying amounts of salt to water samples and observe the effects on freezing point after placing them in the freezer overnight.
