Crazy stuff -- I'm still not sure how I feel about it. We've gone too far in the name of safety in some ways but in others it's needed as we learn more about the risk factors.
Regardless, my kids experience in school is profoundly different than mine -- very little hands on stuff or experiments. Hell, just going on a school field trip with your own kids requires a criminal background check...
Six bunsen burners, test tube racks built into the three sinks, and an eye wash tower in each science classroom of my youth. Yet the only thing I remember doing in four years of highschool is an over-chaperoned field trip with drug dogs and watching baking soda, vinegar, and water expand a balloon (goggles on, of course).
Might as well teach class in a Willy Wonka factory but feed us celery all four years.
There are still a few good high schools left at least.
In the 1950's, teacher labor was subsidized by the fact that it was one of the few intellectual jobs available to gifted females.

This was all prominently on my mind as I broke a mercury manometer during an unofficial experiment in school and was trying to find all the little drops that exploded across the floor and hid themselves in the corners. However, I can say that it's a very efficient way to collect dust bunnies... ;-)
