      Did we conclude that, I thought its still heavily debated.

      Some argue in the 50s and 60s the US was spending Europe’s gold to build highways and infrastructure, gifting Americans the wealth with a continuation of the new deal, they then defaulted in 1971 as inflation eroded foreign debt owed.

      Some feel some form of debt accrual is how we derive such a consumption focused standard of living, which is misallocated capital that ends in someone holding the bag when it can’t realistically be paid back, or when population doesn’t grow fast enough like in Japan or most of the developed countries.

    It was false then but my seventh and eighth grade science teacher told us that blood was blue. My mom was a nurse so I knew that it was bullshit but was definitely confused because he was my science teacher.

    Some children are taught in school that God created the earth. Some of us were allowed to learn that humans cannot effect climate change, allowed to discuss it openly, and allowed to graduate with that idea without ever being corrected. Children are being taught today that slavery and colonialism were good things for some people.

    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.

      I remember my science teacher in seventh grade saying this. I was just very confused because my mother who was a nurse said it was just a dark red.

      I tried to argue this with a science teacher who chose that specific material for a question about phases, and I assumed she was asking for this tricky reason. She marked me wrong and wouldn’t accept my personal research on the topic as makeup. I was humiliated. I hope she’s dead now.

    I have one that was proven false, and then later re-proven true: the existence of the brontosaurus.

    When I was in elementary school, we were taught that they existed, they were big, etc. Then, at some point while I was in college, I discovered that actually what we thought was a brontosaur was a brachiosaur or an apatosaur. And then, when my kids went to school and learned about the brontosaur, I discovered that actually, they did exist!

    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.”

      I was always so confused by the tongue areas because it never seemed to work for me. Especially sweet, I tasted sweet far more at the back than on my tip.

      Were you guys eating coffee grounds in your 5th grade science class? Your next teacher either hated it because you guys were bouncing off the walls or loved it because you were all wide awake and paying attention.

    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.

    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.
