Try your library for educational videos

Franconia's library is about as small as they come, but they had/have a really dynamite video about the American revolution.  It was mostly lectures by a Gettysburg College history professor.  He was good, spoke well and clearly.  He had a few visual aids, a map or two, some paintings, but mostly just spoke standing behind a lectern.  No History Channel style CGI.  I watched the whole thing and enjoyed it.  He told the story straight, the accepted story, no Charles and Mary Beard Economic Interpretation of the Constitution stuff.  Although it was a college level course, I am sure that middle school kids and up would get a lot out of it.  I am sure there are a lot of other gems like this in your local library.
