Ken Burns has wonderful documentaries and I have found that I can use many in my classroom. Creating questionnaires is time consuming, however, for some films, needed, so you know students are paying attention to what you would like them to learn.
If you have Amazon Prime, the documentary is available as Watch Now under Ken Burns American Lives Episodes 12 and 13.
This documentary follows Lewis and Clark on their expedition from beginning to end of life in two parts. Each part is 1 hour 45
