More of Dan Johnson's educational television footage c. 1962, from Hagerstown, Maryland. In this clip he warns that only you can prevent forest waters!
I'm so thrilled you have these videos. I'm passing them on to a friend whose son is a chemistry teacher of the same caliber (lots of hands-on teaching).
Thanks so much for sharing such a valuable resource!
