Categories

This module have been divided into three sections: readings, hands-onactivities, and challenge activities. The readings are just that, readings that will provide you with some basic understanding of the chemistry of the problem of ozone depletion, as well as introduce you to some of the people who have spent their lives investigating the scienceof the ozone-CFC issue. They are listed in an orderly fashion, but the links on each page allow you to readthrough them in any order you feel like. The hands-on activities are experiments and exercises for you to do in the laboratory. Under the category of challenge activities you will find quizzes, research projects, and WebQuests; that is, activities that are more oriented toward thelibrary than the laboratory.

Navigating the module

There are many links within this module. The links you see within the text all link to otherpages within this module. Links to outside webpages are listed at the end of a page, under theheading "For more information, at other websites..." Clicking one one of these links will open a new copy of your Web browser. You may have already noticed that some ofthe links in the text are green, while others are brown. Green links connect you to other pageswithin this module. A word linked in brown will connect you to the glossary definition of thatword. For example, click on the wordozoneand a definition for ozone will appear in a pop-up box. Go ahead. Try it.

Now that you know how this module works, you may begin your explorations throught the world of ozone and its protection. Have fun!
