First of all, good for you!!!
It is hard to say without knowing more about your group and how much basic understanding they have.
When I tell people about the crash course, I want to get them to watch the whole thing so I make sure I share the parts that grabbed me the most. what grabbed you the most? What made you go wow?
For me it was the stadium filling with water at an exponential rate and the copper mine and the discussion of mules. Maybe that's because I do some of my farming with horses. See, it does depend on where you are starting from.
Good luck with that and let us know how it goes

I have recently watched Crash Course and will be presenting it to my association tomorrow. I only have an hour to show a few chapters, so I will be giving everyone in attendence a copy of the DVD. If you could only show an hour of CC, what chapters would you present? Thank you!
