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

Safety? In a classroom setting, what's the worst that's likely to happen? Eyestrain? Carpal tunnel? I'm glad I learned automotive before computers. Getting dirty out in the shop was part of the appeal to me. Learning hands-on is a much better method in the service industries. I've hired book educated people that didn't know which way to turn the wrench because the book didn't tell them and they never had to do it before.
