Time Train's video: What high school students learned in 1950

Bacteria: Friend and Foe This film starts out with high-schooler Ted struggling to see bacteria in a microscope and being helped by his older brother Frank, a bacteriologist who bears a slight resemblance to Dr. Radford Baines. Unfortunately, it's not long before this becomes a standard dry EB science film about the various kinds of bacteria. There aren't even any killer shrews in it. The graphic elements are mildly fun, with title cards in various shades of Pepto-Bismol pink and a sort of periodic table of bacteria on the wall that Frank refers Ted to. But mostly this is the sort of film most students probably slept through.
