I'm starting an after school auto program for middle school students...any ideas?

Joe Dokes couldn't have said it any better as a teacher. I think that's the best advice you'll ever get for free!
BUT.. as he so elloquently states.....Safety is Paramount. Glasses are a must. Along with procedures. Rust and dirt find there way in eyes very easily, the use of tools they probably have never seen much less heard of, and possibly weight of pieces and parts you'll be training with..
I wish you the best though, what a cool way to introduce the trade, and our hobby to the younger generations....
