Lesson on what the Ozone layer is, why it's important and what's happening to it.
Includes a card sort and worksheets, both of which are found on the slides at the bottom of the ppt.

Uploaded as I was realising it's difficult to find a simple lesson on this. I have made this for delivery to a year 9 class so have included some of what happens on a molecular level but not in much depth.
Hope it's useful :)
