    I was taught that Jupiter had 17 moons, Saturn has 12 and Pluto has 1. Many more have been discovered since.

    Then there’s the whole “different areas on your tongue taste different flavors.” Like you only taste sweet with the tip of your tongue, the middle tastes salty, etc. I remember being given various substances by my fifth grade teacher like sugar, coffee, lemon juice, table salt etc. and we tried putting them on different areas of our tongues and we were like “…no, we taste everything everywhere.”

    Basically everything I can recall being told in D.A.R.E program classes (war on drugs era propaganda taught in public schools in the USA) was utter nonsense and fabricated bullshit. After actually having personal experience with most of the substances they vilified, none of the effects - good or ill - are what I was taught in that ridiculous program.

    On the contrary, some of the fear tactics they used made me curious to investigate on my own. The breathlessly scared rural teacher describing the mind bending effects that “magic mushrooms” was supposed to have sounded fascinating to teenage me. In reality, they are very fun and therapeutic to use, but nothing like the wild Alice in Wonderland mind journey they made it sound like it would be.

    Physical Vs chemical changes.

    It was typically taught that physical changes are differentiated from chemical changes because they could be “undone” or that they had “no chemical reaction.” Which was very confusing, because you can’t uncut paper, and dissolving stuff in water clearly results in different chemicals being produced, yet both were examples of physical changes (actually the latter is sometimes taught as a chemical change). Furthermore, most chemical changes are actually reversible.

    It has since been recognised that this classification is BS, and most changes actually exist on a continuum.

      I am teaching this next week. It is sometimes painful how simplified we have to make content for middle school. You are expressing what science teachers hope for from students. You were curious enough to explore further and ask questions, the true purpose of science.

    A huge number of aspects of the US’s geopolitical enemies, and its own mythologization of the Founding Fathers and early settlers.

    There was also a really bad political test with liberalism on the left and conservativism on the right, and we had to take a test and put what we got in front of everyone, which was very strange.

    In my college Econ 101 class I was taught that “economic liberalism” would lead to political liberalism. I knew that was a myth back then, but my professors insisted. Twenty years later we’ve got economic nationalism and political fascism taking over everywhere.

    The asteroid that killed the dinosaurs was seen as just one of several possible theories, rather than accepted fact.
