They then analyse the trends in the data to determine the locations of the different atmospheric layers. Students analyze how their own homes use electricity. They then calculate the amount of nitrogen oxide pollution their homes produce and propose ways that nitrogen oxide emissions could be reduced. They then use the analyzed data to determine how to implement a publicity campaign that would change people's habits regarding ozone pollution. A list of key concept words is provided.
Students compare the condition of exposed materials to the condition of unexposed materials.
In this field laboratory exercise, students design an experiment to study the long-term effects of ozone and other air pollutants on rubber and nylon. They set their samples outdoors and observe changes in the samples over a three week period. In the News Students apply their knowledge of tropospheric and stratospheric ozone to a new situation by classifying magazine articles titles as relating to tropospheric or stratospheric ozone. Slide Show Students design and produce a computer slide show which highlights the main concepts they have learned about ozone location, sources, effects and solutions.
