In 8th grade metal shop class we were taught how to do foundry work (make the sand mold, melt and pour the aluminum (making rock hammer handles), demold, use the metal lathe to smooth and knurl the handle), shape and how to correctly harden the rock hammer head, and how to thread the head and the shaft to put it all together. Also taught how to use a stick welder and oxy-acetylene torch to weld and braze (surprised the teacher because I already knew how to do those things (my family had a lot of auto body workers so I learned early on). Learned a lot about the metal trade.
9th grade was wood shop, learned how to use all the different wood working tool, hand and floor models, still to this day love to work with wood.
10-12th grades I took mechanical drawing/architecture class - no CAD machines or computers back in the 60's-early 70's, T-squares and mechanical drafting machines. 12th grade they didn't have a true advanced class for 4 of us so we designed/redesigned things for the school district. One assignment I got was to design a new playgrounds - not a easy as you think, you have to take into account all the state/federal safety regs and the ages of the children who will be using it.
Oh, I also had to, at times, push start cars with weak batteries. Luckily I lived in a somewhat hilly area so it was a short push to get to a downhill. I had a 1964 Chevy Impala (3 speed on column that I moved to the floor). I used 2nd as it seemd to be easier.
