1. Take the Smog City Challenge
2. Submit the Ozone, CFCâ€™s Greenhouse Gas Portfolio
Ozone, CFC's Greenhouse Gas Portfolio
This assignment is to show me how well you understand the unit we have been covering. You will collect all
of your work in a shoebox that you will bring to class and keep in the classroom. Pick a topic from Ozone,
CFCâ€™s or Greenhouse gasses and use this checklist to complete your portfolio.
*Bring in a shoebox to keep your portfolio contents
*Build a model depicting some aspect of your topic, with an attached key describing the components of your
model and what it has to do with your topic
*Bring in a copy of a current article relating to your topic and one paragraph on how it affects you personally
*Graph the Antarctic Ozone data, and write a paragraph interpreting the results of your graph. What does
this graph tell you about ozone levels in Antarctica?
*Bring a household item that relates to your topic and write 1 paragraph explaining how it is related.
*Do an artistic interpretation of your topic (poem, picture, collage, rap)
*Type a letter to one of the following, signed, addressed and ready to be mailed
