I know a lot about this time period. I've taken a few that have covered the Great Depression in depth. I'm not an expert on 1930s U.S. History, though, so I'd have some research to do on this era. Additionally, I would like to limit the scope of this unit idea to maybe just the family experience of the Great Depression or dust bowl. It would allow me to cover economics and geography within a greater historical context that isn't too overwhelming for students.
I'm conflicted about whether I want to focus on the general family experience in the Great Depression, or the experience of Dust Bowl Families.
I'd spend a lot of time on primary source analysis, getting students to think like a historian. The Great Depression is full of all types of primary sources, from songs, print documents, to letters, etc. I'll need to do a lot of research in order to pick out the best and most appropriate sources to be analyzed during class.
One of my favorite Ken Burns documentaries chronicles the Dust Bowl. The preview can be viewed here.
