I've been doing a GIS Day presentation at a local middle school for the last few years. To break up the presentation/me talking, I often will show one or more videos to highlight specific concepts related to geography and/or GIS. I mix it up each year, but here are some of my favorites in case they're useful to anyone else. 🙂
Also would love suggestions from others. I have quite a few I haven't used anymore because they're so outdated.
