I went through the two websites posted here for graduation year 2008. The only incorrect thing I was taught that I still believed was:
"Learning styles (visual, auditory, kinesthetic) determine how you best learn"
False. Huh.

I just picked up a book on this! There is, of course, an incredibly racist history to the use of these concepts.

Feel like a lot of the "myths" are also just because you're not going to teach a 16-year-old about quantum mechanics to explain why table salt exists
Well there are deepening levels of understanding depending on the learner's pre-existing understanding of the world (e.g. matter > atoms > protons/neutrons/electrons > fermions), and there are things that are just plain incorrect, that were assumed to be correct, because science advances (e.g. Pluto is a grey ball of boring nothingness very similar to Mercury).

Fruit and vegetables being separate categories: Fruits are actually a type of vegetable. Additionally cucumbers are melons.
Cyan being a light blue: It is actually 50% green.
Simple machines are fundamental: They completely ignore compliant mechanisms and aren't atomic. Actually atomic mechanisms would be defined by the type of force, the shape, and the compliance.
The only form of Socialism is Marxism and Communism and Capitalism means markets: Look up Mutualism or Syndicalism.
Basically everything with pop psychology.
I am sure there are more, but these were just top of my head.

In the US, Trump would demand this site be “de-woke-ified” to remove “conservative bias” by having any conservative fact disproven removed from results.
The economy works and real estate is always a good investment. Also, the best thing that can happen to a nation is to be defeated by the US, because the US will then rebuild their infrastructure. The only example that teacher would cite was Japan.
Fm radio travels in waves while am radio travels in beams. This wasn't a science teacher though. This was a media teacher's wisdom.
