EVOLUTION OF EARTH SYSTEMS
OZONE ACTIVITY
1. You will progressively be given several images (ozone images) which are compilations of satellite data measuring ozone levels for the entire Earth. When you receive the first image, become comfortable with it by finding known locations, and using the color key to determine specific values.
2. Next, identify specific areas where ozone is anomalously high and / or low. List those areas, identify whether they are high or low, and specify the ozone quantity.
3. Continue with the remaining images, looking for anomalies and recording them as in step 2. Be especially alert for trends – that is, places where the anomalies are consistently present, and whether they are growing stronger.
4. As you identify trends, take note as to whether they are specific to latitudes or times of year.
5. Pause for a class discussion.
6. Finally, write a newspaper article, one that could be found in the Times or PI, describing what you have discovered.
7. The notes from steps 2-4 and the article are a portfolio entry.
Note: You can access NASA GSFC and retrieve any images for any day by going here.
