> I was a High School teacher (Chem/Phys)… <
Me too. When I had about 10 years to go before retirement, I moved from chemistry to physics, just for the variety (I have a degree in both).
Lucky that I did. My idiotic school district eliminated the math requirement for those classes. So it became come one, come all. And that included the special ed kids.
That was bad enough in physics. But in the chemistry classes those kids would throw chemicals around. It got so bad (and dangerous) that many chemistry teachers stopped doing labs.
So as usual, the good kids had to pay. No lab experience for them.
I sure miss teaching the smart kids...
