So my mom just took over for the head physics teacher at her high school and the old teacher left behind a bunch of equipment. We aren't quite sure what some of it is used for. Already sent an email to the manufacturer about it, but I thought I would post pictures of the equipment here to see if anyone can help. Thanks. Sorry if they take awhile to load up. There is a foot long ruler included in the pictures for scale. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.
