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

Safety is always first with kids.
Then basic tools and uses. Also the importance of tools being organized.
I like the U tube classes. let the students hunt for them.

Ask scrap metal dealers for donations of materials. A rear end from a scrap dealer has a $7.00 value where a junk yard could be over $100.00

I hope you do well in this quest.
