When I was in 1st grade, I said that electricity can be gained via water (hydropower), everyone started laughing at me until my teacher said: "He is right."

The whole class went silent.

When I was in 8th grade I made the (apparently controversial) statement that the number 2 is 2/3 of the number 3. I had 5 people try and convince me otherwise by doing long division on the board and saying, "see, it's not 2/3, it's 0.66 repeating." Bunch of mouth breathers.

I got downvoted like crazy for saying that a nurse told me that cold water and soap kills germs just as well as hot water when washing your hands. Linked some sources and everything. Then people started calling me a troll.

This was something I learned only after covid hit. In theory really hot water would kill germs better, but it would need to be so hot that you'd end up with burns in your hands

Grade 7 (Canada), we were learning about medieval Japan in Social Studies class (basically history class). I made a comment that the Japanese bombed Pearl Harbor, a kid said it was the Germans and some people backed him up. Teacher said she forgot who bombed Pearl Harbor but it wasn't the Japanese. If only smart phones existed back then.

Just the other day, there was a thread about "What do people get wrong about exercise?" I said that cardio is not about burning calories. It's about depleting sugar from your liver so no new fat is created. When you eat, the liver processes the calories into either energy or fat storage. When you exercise, the body uses sugars from the liver for quick energy. This is why marathon runners carb-load before a race. But even if you're not running a marathon, the principle still works. Do half an hour of cardio a day, deplete the liver, and no new fat will be created. Then, when you're just sitting around, there's no sugar in the liver, so the body has to break down existing fat for energy. Hence, you lose weight.

But the myth is that you eat x-number of calories, and then you have to do x-number of hours of cardio to burn those calories off. That's not how metabolism works. I even provided [links](https://youtu.be/LRkcvDyQwho?t=4283) from an endocrinologist explaining it. I mean, I agree exercise makes you lose weight, and binge eating sabotages the process, but it's not about "burning calories". It's about depleting the liver of glucose.

Of course, people don't like reading anything that challenges their pre-existing beliefs. So I had some guy calling me an a*****e, etc. I politely explained, "Just because you disagree, doesn't mean I'm automatically wrong."

4th grade. We had our first laboratory class and we were learning about the lab instruments and basic safety.

We were divided in around 4 tables with 6 students each, and each table had a flask with coloured water in it. The teacher told us to by turns each one grab the flask and pretend to mix the liquid by spinning it.

The first kid in my table grabs the flask but in a way that his hand covers the flask's mouth. I tell him such and that he should grab it by the neck sides instead of the mouth because if it was acid it could splash to his palm and hurt him. The other kids at my table started calling me a crybaby saying that it obviously "isn't acid" and that it was only "coloured water like the one they use in my juice", and they all proceed to hold and mix it improperly.

Eventually the teacher teaches us the correct way to hold flasks and mix them after seeing everyone grab them incorrectly. He tells us to grab them by the neck sides (just like I said) and to not cover the mouth with our hands because if it was real acid we could get seriously hurt (just like I said).

I still get a bit salty when remembering that.

In 5th grade we have a problem on Math class with mirroring images. It asked if you are driving in a car and look in the rearview mirror how would you see the ambulance embleme if an ambulance car was driving behind you. I said you would see AMBULANCE because (at least in my country) those signs are intentionally put on mirrored, so you can see it normally in a mirror. Everyone said I was stupid even the teacher. I still remember it after 8 years.

years ago when I was in middle school, two mentally challenged kids got into a fight in class. it wasn't like a full out fight, mostly pushing, but they definitely got into it with each other. turns out kids heard about this, and the egged them on so that they would fight outside during lunch. I somehow found out about it, and when I got there, the two kids started to have a full on fist fight. As all the kids surrounding them cheered I rushed in to break them up. It was difficult breaking it up because the two kids really were going after each other, and no one else really helped to break it up. Eventually teachers caught wind and broke it up. As they did, kids started to literally boo me and curse at me for breaking up the spectacle. I was shocked. Don't get me wrong, I'm not some white knight and I totally get it that when you're a kid you love watching fights. Heck even as adults we have some primitive innate entertainment by watching people duke it out, but there was something incredibly wrong about watching two mentally challenged kids being egged on to fight to the amusement of kids who were laughing at the situation.

I’ve had many booed moments, but this is a more recent one. In my science class we were watching a few documentaries about the US space program, and the topic of pollution came up with fuel consumption and in the midst someone asked about where the parts of the rocket go once they are abandoned by the spacecraft. I commented how it just falls and NASA pretty much just hoped that it didn’t fall on people. One of the reasons they launch out of Florida or a cape is so the parts end up in the water and not hitting civilization, but nobody believed me since it would be then that NASA is polluting the ocean.

I was once in a chorus in my community college and they had interesting social dymanics. It was primarily older white women, who were the alphas of the group. So we were doing a latin american carol called "vamos pastorcitos" and there was debate between them about the pronunciation of the "c" I said the soft c is pronounced like an s, an old lady in the group said it was pronounced like the ch in cheese. I said "you're thinking of italian, in Spanish it's pronounced as an "s" or in many european spanish dialects like a "th"" The choral conductor went with her churchy old lady friend and they all pronounced it like "Vamos pastorcheetos" it still haunts me to this day.

The question in history class was "who sacked Rome" and I raised my hand and answered "the Visigoths." Everyone laughed along the lines of "that's a ridiculous name there's no such thing as the Visigoths" and that the Vandals sacked Rome, which is where we get the word vandalism from.

While yes, the Vandals did sack Rome, so did the Visigoths in the year 410.

In second grade (~8 years old) we had a presentation in the school library regarding something related to the solar system. The presenter asked if anyone knew the speed of light. I raised my hand and proudly said 186,000 miles per second (Thank you, Magic School Bus). Apparently his pre-prepared speech did not involve the first person having the correct answer, and I could tell he really wanted to say no. Thankfully he did not.

A chemistry teacher in high school once very solemnly warned students of the dangers of dihydrogen monoxide. My dad had told me this joke before, so I knew where it was going. While she was going on about how it causes flooding, thousands of annual deaths, and has even leaked into the water supply (in high enough doses, it's poisonous), I started cracking up in the back. Literally everyone in class looked at my like I was a sadist, and one girl asked real seriously "why are you laughing?" until the teacher started laughing, too. She had me come to the front of the class and write out the chemical formula for the whole class, where they learned that dihydrogen monoxide = H2O = water.

Also, got into an argument with a kid in the 6th grade that 100 times 100 was 10,000 and not, in fact, 1000. When I put it on a calculator, he said the calculator was wrong. Then we asked a custodian passing by, and she agreed with him that 100*100=1000. (-_-)

I was working on a team of people building a race car. I told them a part that was technically strong enough should be built heavier to handle shock loads from bad track conditions.

I got told I was a m**on and it would be fine someone else ran the numbers and it would be fine. So I built the parts put them on the car and lo and behold it broke and the car ended up on it's roof.

You'd think that would be validation of my opinion, and people would agree that I was right. Not how it happened. I was the a*****e because I built them, so it was my fault.

Once in middle school, the teacher said that carnivore dinossaurs like the T-rex appeared in the jurassic era, then I said that the T-rex was actually from the cretaceus period. The teacher and the some students said that I was wrong because "It's called Jurassic Park" and s**t. On the next day, I brought some sources from the internet that agreed with me and the teacher corrected herself after doing some quick search on her own, but that didn't stop me from getting nicknamed "dinossaur" in class.

A teacher in biology GCSE was discussing a food pyramid of a river habitat, and she claimed that "10 Sprey" were at the top of the food chain. I pointed out "Miss, I think that says '1 Osprey'." She snarled and said "Fine. Everyone, anon thinks he knows better than me, so now it's 1 Sprey." The whole class groaned and were muttering as they had to cross out what they'd written and rewrite it, and people on my table were giving me evils and telling me to be quiet. Utterly ridiculous that I even passed that subject.

My daughter had a teacher in third grade that told her that swedish pancakes were really just crepes. She had no idea what to do since her teacher told her something that she eats all the time wasn't what her parents told her it was. Her next project about a week later was about other cultures so I had her do a report on Sweden. Guess what was included in that report and guess what she brought to class to share with everyone during her report out to class. Teacher said nothing but did give her an A.

I don't know why schools try so hard to FORCE every kid to have the same set of skills. Everyone needs the main points of history, basic math, reading, spelling, and grammar. Everything else some people won't like and that's okay. Some people will hate reading books and writing reports or essays. Some people will hate lab experiments. People are all different.
