Putting aside the school idiocy in this case, I'm disappointed my kids will never experience the wonderful, practical (and sometimes dangerous) lessons I had at school. The primary school teacher who ran a string from one end of the basketball court to the other, with a straw freely running along it and a soda bulb taped to the straw - pierce the end and wham - instant rocket-powered monorail. Or the high school teacher who put just a little too much sodium metal into a bowl of water. Skittering across the surface, flaming then BANG! We were scared shitless - it was FANTASTIC.
It's not all bad though - it means that I do these experiments at home with my sons. Burning magnesium; rocket candy; gallium and aluminium alloying: if a litigious society won't let kids learn these things at school then I'll have to do it myself. It's fun for me too, of course, which is a personal upside. On the other hand, it it does mean there are plenty of kids who will never experience the joys of experiments because their parents don't have the science/inclination/resources, and that is the real loss.
