This document summarizes a science lesson on the ozone layer. It introduces the topic of the ozone layer and explains that chlorofluorocarbons released by humans have damaged the ozone layer, creating a hole. It directs students to a website for more information on the ozone layer and hole. The lesson also includes roles for a classroom activity where students role play as different characters involved in a news story about the ozone layer.

1. • Hole is concentrated at poles, but pockets can be
found globally.
– Why should you care?

3. • RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.

4. -Nice neat notes that are legible and use indentations
when appropriate.
-Example of indent.
-Skip a line between topics
-Don’t skip pages
-Make visuals clear and well drawn.

5. • RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.
• BLACK SLIDE: Pay attention, follow
directions, complete projects as described
and answer required questions neatly.
