teach them how their local, state, and federal governments work.

A class about how government functions would be awesome, although I have serious doubts such a thing would be possible to do in an unbiased manner. First time someone's son or daughter comes home telling their parents how they have switched parties people will start raising hell. College can't even do it without picking a side. There would be boycott on public schools if it was tried at a younger target audience.

As for the science argument, I believe in anything that yields repeatable results. Earth is round. Gravity exists. The idea of evolution gets tossed around because the archaeological record of bones seem to indicate beneficial mutations are passed onto the next generation. There's no other way to currently explain it. It shows a possible solution to the mystery. There's enough facts stacked to support it that it's practically become a fact. My issue with the creationism theory is that it fails to ask any questions, answer any questions, and from a scientific standpoint anything that asks nothing and offers nothing is nothing.

biology, anatomy,

The amount of people who have no idea how their own bodies work on a rudimentary level is deeply disturbing. The sex education in schools a joke. It tells as little as possible to the point of being almost useless. Fuck equal baby. No shit. Why an adult feels the need to deprive their children of this valuable information is beyond me. At the very least an anatomy textbook should be given to public high schools. It might even decrease teen pregnancy numbers.

scientific experiments.

Weirdest thing about science class: Knowing the scientific method was never on a test at my school.
