I told you Paul would get it right for you!!
And yes, I did get carried away...and so did the kids. It was honestly the best unit of work I have ever taught, and I have never seen my class so motivated.
Antarctica is a complete unit. You can learn about evolution and wildlife and science and history and language and computers and the environment and photography, and the list goes on - all at once! Everything you need is there. You can teach about everything when you teach Antarctica!!
To me, teaching about Antarctica was like a balanced meal...all the food groups were proportionally represented!!
