In the 1950s and 60s Bell Laboratories sponsored a series of science education films for school kids. These films were originally made for TV specials, then distributed to schools. They were often shown in science classes and special assemblies. The most popular was probably Hemo the Magnificent, which was about the circulatory system. Since I first blogged about Hemo over 2 years ago a few You Tube videos with clips from the Bell series have surfaced.
Below is an excerpt from Meteora: The Unchained Goddess about weather. The graphics and animation were wonderful for their time. Note that the opening sequence of this 1958 film warns about man made global warming!
