When I was in 6th grade, they let us use a spot welder and press brake. I still have the box I made out of folded sheet metal from that time. We also had to make a little container out of folded sheet metal that surrounded an egg. The metal shop teacher piled weights on everyone's in the class until the eggs broke.
In 8th grade (2001), they let us use MIG welders and the project was to make a crane with the maximum cantilever given a set of counterweights and a limited amount of 1/8"x1" steel. I remember the entire class standing around watching as we piled weights up until they failed spectactulary.
It's not a coincidence that those are some of my (few) vivid memories of middle school. I remember being bored in a lot of classes that simply weren't challenging enough, but never in metal shop or science class.
They don't even have metal or wood shop in the middle school anymore. They barely have it in the high school. It's probably some combination of safety and budget, but can anyone imagine the school allowing basically 13 year olds to handle MIG welders anymore? It gets hot! Or sheet metal in 11 year olds hands? It's sharp!
By high school all of the best and brightest are maxing out AP classes for college applications. There is no time left for 'fun' classes like metal shop if you aren't going to trade school. (That becomes quite apparent when you get to college and there are mechanical engineer majors who can't work a hand drill.)
If we lose all of this stuff, we are going to lose the next generation of engineers. FIRST robotics is a great program, but we need more things like it.
