Mine might be the last generation of students to have watched educational movies via an actual film projector. The switch to VHS was pretty much final by my junior year in high school. And even my sophomore year, we only saw a few in Drivers Ed.
When I was in elementary school, we had these filmloop cartridges that you plugged in to a small viewer. I only remember watching one about polar bears because the bear took a pretty nasty fall, and being 7, I thought that was pretty hysterical.
But it was one I saw in fifth grade that has always stuck with me. It was shortly after we moved to Tracy, and I don't even remember why we were seeing the movie.
It was to educate us about the perils of vandalism. The only part that I really recall clearly is a scene where two kids decide to hurl a rock (or brick or cinder block) off an overpass. It smashes through some guy's windshield, and we get to see him all cut up and covered in very unconvincing stage blood whining something like "I'm blind! Aaaaaaa!"
Cheesy though it was, I've never chucked a cinder block off an overpass.
I've bought a handful of discs from the Educational Archives series and I've perused the Prelinger and AV Geeks collections at The Internet Archive, but I have yet to find out what this is called.
I'm usually pretty good at finding these kinds of things, but so far, no luck.
