Members of Mrs Marston’s group may notice a slight difference in the content here, we are studying the same topics, just in a slightly different order. Don’t panic!
We had a guest today, welcome Miss Wicher, who will be joining us on our Pilot Journey. Excellent discussion today to round up Antarctica, as we considered the arguments for and against the future development of the continent. Lots of Geography came out, including the hot topics of migration and the development of LEDC countries. Don’t know how, but it did!
Congratulations to Laura at the end of the double lesson, who remembered FUGIS, in my escape home by providing me with ‘knowledge’ at the door quiz! 
We then studied this image and discussed if/how they were associated.
I was quite surprised that many of you had a good background knowledge of Ozone depletion, its causes and impacts. We then watched Ozzy Ozone to bring everyone up to speed on the issue. We then discussed the chemical composition of Ozone and how it is formed.
In Monday’s lesson we’ll consider how Ozone is destroyed and the impact of this on human life in the Southern Hemisphere. We’ll also discover why the depletion is greater over Antarctica. If you want to read more on Ozone, please refer to my previous post.
Sadly, our network is too slow to show an excellent Google Earth animation of Ozone levels over time. For those of you without Google Earth or the updated version, you can view a video clip. Notice how Ozone depletion migrates to and from the Polar regions according to the seasons. I wonder why?
There are some other great animations here as well, including the collapse of the Larsen Ice Shelf.
Finally, thanks to the individual who left me the secret messages hidden on my desk. I laughed.
