Thought I'd share my presentation slide deck in case any of it is useful to anyone. My audience was seventh graders, so I went for highly visual with minimal words and broke up the talking parts with a few videos. Because of all the visuals the file size is about 31 MB, which is too big to upload directly, so here's a link to download it.
Download the slide deck from Google Drive >
It's meant to be run through PowerPoint, i.e., Google Slides won't give you the full experience of slide transitions, effects, etc. But I put notes for each slide and links to image sources, almost all public domain/creative commons stuff, so hopefully it's easy enough to repurpose with your own images or to remake it to work better with Google Slides if needed.
Hope everyone had an awesome GIS Day!
