Study people

I would choose, The Romans and the Germans. Both are militarial cultures and moved from autocracy to democracy through the art of war. I think it would be a fascinating study and there is ample research to be found on the net. Good luck and let us know how you did.

How about the people of dafar? The suffering of their people and the way of the land & culture are tear jerking and will make the class just go quiet! Africa is a interesting country with soo many different people, religions and regions. I watched a show on Congo and the women of congo,made me cry! Their culture is crazy and interesting.1of 4 women have been brutily rapped, children stolen and enslaved as killers, it's crazy to think how many have been killed or fled for safety. something like 4 million people have been killed a modern genicide.... Learning about it made me a better person, i can tell you that!

I would choose any culture in south america as they were the richest in there era. They then all had to move on as of water problems and agriculture problems like the problems australia is facing today in the se qld region

Indus Valley Civilization, The Chinese, I'd find the oldest cultures and civilizations I could find. Much more to work with, more advanced, and typically you find much wisdom...

two cultures? Hmmm.. I think I would go for the Japanese Culture. the story of ninjas, samurai and Geisha amazes and intrigues me. I also like to learn more about the history of Egypt, its Pharaohs and how amazing the Great Pyramid of Giza was built. I am pretty sure it's worth the research. good luck!
