This Ozone Data Comparison over the South Pole lesson plan also includes:
Did you know the hole in the ozone is seasonal and filled by January every year? The lesson uses scientific measurements of the ozone over the South Pole to understand patterns. Scholars learn that the hole grew bigger annually before environmental efforts help it shrink each year.
- Challenge scholars to explain why some ozone is good (in the stratosphere) and some is bad (in the troposphere)
- Extend the lesson by comparing the ozone in the Arctic and the Antarctic
- Helpful prior knowledge includes the layers of the atmosphere, the structure of ozone molecules, the role of ozone in protection from UV, the causes and consequences of ozone depletion, and dependent versus independent variables
- Integrates science and math topics
- Uses real data that is updated each year
