Graphing Stratospheric Ozone
This lesson uses NASA images of Antarctic ozone to motivate a "how-to" graphing lesson followed by more sophisticated examples of graphing using and images from the Neumayer Antarctic Station. Links are provided for investigating current knowledge of the Ozone layer, and the impact of human activity on this vital part of the Earth system.
1. What trends are shown by graphical analysis of ozone measurements over time?
2. How are different measurements related to each other and to possible causes of the trends?
1. Studens will investigate ozone chemistry and issues around the preservation of the Earth’s ozone layer.
2. Students will know how to read false color images of ozone concentration.
3. Students will be able to construct a correctly labeled graph and interpret trends from graphs of data.

VIEW THE LESSON
The website has three parts: Introduction to the lesson organization, which is really a page for teachers, graphing section that guides students through creation of a plot of Ozone thickness against time, and "Ozone Chemistry", which offers opportunities to study other data sets, and read on-line information about the ozone layer and efforts to track and preserve it. Links to information at other websites are provided.
Browser skills, basic knowledge of chemistry and atmospheric terms is helpful.
