As I plan for Semester II in Big History, I am considering how many classes to devote to the study of agriculture and early civilizations. In particular, I am identifying the fundamental, must-teach topics to include. Each of my classes lasts 60 minutes, and this unit will include the Museum Project. I am thinking about dedicating 20 class periods to cover this unit. How many classes do you usually spend on it? And for those who teach Big History, do you include the Museum Project as well?
