The moon was spun out of the same stuff as the earth. That was fact in the early years of my education. A few years later there were multiple theories: co development, captured a wandering planetoid, the Thea impact, and a fourth one I can’t remember but I think it was something dumb like planetary mitosis. By the time I graduated the Thea impact was considered the only viable theory.
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.
That fluoride and vaccines are bad for you… tbh, I only believed it for 2-3 weeks until I did my own research, but it was a frightening clarification. Didn’t believe that teacher a single word after that.
I think people underestimate the problems with teeth hygiene. It can cause dimensia, so teeth should be brushed before you eat, though avoid mouth wash.
And don’t forget to floss! As soon as I learned that my gums don‘t bleed because of the metal thing, but because food between my teeth decays and that decaying decays my gums, turning it all into poop, I started to floss every second day.
Why should I avoid mouth wash though? My routine is floss - mouth wash - brushing
Just the cancer causing it does.
By the time I was in school the Bohr model was already proven inaccurate, but was taught anyway because the orbital model is too esoteric for teenagers 🙄.
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!
The myth that glass is actually a very thick liquid. It’s actually much weirder than that. https://gizmodo.com/the-glass-is-a-liquid-myth-has-finally-been-destroyed-496190894
The United States operates on the principle of three co-equal branches of government, which check and balance each others power.
This is painful.
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.”
The D.A.R.E. program.
We congratulate drugs for winning the war on drugs.
I’m addicted to dopamine, and I’ll take any drug I can to get more of it.
Trickle down economics are an effective way to redistribute wealth
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.
You’ll wet your bed if you play with fire.
Never heard this before!
Could be a Portuguese thing.
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.
Drugs Are Really Excellent?
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.
I distinctly remember my fifth grade teacher trying to pull that.
I was chucked into Christian school.
So… a lot of it.
*everything
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.
