I think Sci-Show's debunked that. And just about every other science channel or indeed, factoid-spitting channel I've seen. I never really learned where that idea came from, though. No explanation has ever gone beyond basically saying, "some Swedish guy was dumb." No one ever can seem to say what made that researcher think that, or what fallacies were present in his research, or perhaps what biases led him to want to publish those results. It's kind of annoying, really, how little you can hear about when science went wrong, and what leads people to faulty conclusions. A lot of it doesn't go any further than, "this dope thought this, but we, the smart real scientists, tried that experiment and didn't find that result, so the other guy is wrong, and probably a dummy". People seem to be too preoccupied with saying, "we're right, he's wrong, neener neener" to actually give insight as to ways science can go wrong, and what sort of traps scientists can fall into, which I think is a missed opportunity for a pretty interesting topic.

I did have a teacher who explained the atom model is simplified to fit on the printed page, and that the reality is the electrons are flying about in every direction, changing levels, but that in essence the levels depict it abstractly and the numbers in the shells are correct. I was probably 1 of 2 people who understood that. Being that it was 1971 now I wonder what school he went to that taught that subject in an advanced manner. It may have been a particular interest that drove him to extra classes in a subject he fulfilled requirements for years before, and additional reading over the years since. I do that, I read lots of science stuff, especially space stuff, and read just about anything ever written about cars, trucks, off road vehicles (like earth moving equipment). Thu si know more than much more educated people about very narrow particular information that I just find fascinating. This really took my career very far before it was stopped by becoming disabled.

Many fields of study have a really hard time admitting that an issue is more complicated that they can explain, regardless of whether to children or adults. Far more humility is needed in how we articulate how confident we are in results. When I started pursuing my degree in science I was blown away at how huge of a chunk of the information we take as 'fact' is not actually evidence based. Here is a great example, did you know that the speed of light has NEVER been measured to have the exact same value in two different tests, yet we call it a constant? The value we attach to the 'constant' is actually an average of several very similar, but slightly different measurements. Consider the second clip of this video where the woman talks about atoms. Our current model suggests a cloud, yet that's never been observed, so we speculate that our observational tools must be making it go away. In other words, rather than accepting that theyre wrong, they moved the goalposts and said theyre still right, it's just not provable with modern machines. While discussing how every previous model of atoms turned out to be false (even though the technology we made using them worked perfectly fine) the narrator still claims over and over that this time we've definitely found the real one, a claim I'm sure was made by proponents of every single outdated, unverifiable model.

How do you feel about some states wanting to include creationism in the Science curriculum? Teachers are the best, I come from a long line of teachers as far back as the early 20th century and I know that for all that time teachers have been underpaid and sometimes unappreciated, without teachers there's nothing.

The problem with "5 senses" is that it depends how you define distinctive senses. A lot of people would lump those extra 3 into "touch", maybe because they're all related to how we physically interact with the world - for example you sense temperature when you 'touch' something warm or cold, even if it's the air. I've seen articles that argue we have dozens of senses. What about thirst, hunger, fatigue, the ability to sense the passage of time, pressure (the ability to pick up an egg without breaking it goes beyond the simple sense that you're touching it), the need to pee, the need the breathe (i.e. carbon dioxide levels in the blood), etc.? And then there are senses that follow on from others. For example, you can get a sense of the physical space you're in by listening to how sounds in the environment reverberate. Blind people tend to be very tuned in to this - essentially it's like echolocation. Technically, it's just hearing, but you are 'sensing' a lot more than sound.

And that's fine; it's works perfectly well for understanding the difference between solids, liquids and gases. Would you demand that even at this level we must already show a mush of quarks and gluons in the nucleus (and do we have a good enough understanding to diagram that anyway?), electron orbitals etc? It's not a lie; we're deliberately choosing a suitable level of abstraction like we do every day for everything. Later we move into understanding that atoms have a heavy, positive nucleus, and lighter, negative electrons moving around outside. This is a fantastic model, because it's basically sufficient to underpin most of chemistry; you can basically understand most chemical reactions, valency, radioactivity, and even stuff like plasmas, hydrogen bonding etc. If you want to go to a deeper level, you can do so later in your education (bear in mind this video is supposed to be about what we're taught in elementary school; the "planetary" model of the atom is already very advanced).

Whichever theory we have now still has a possibility of being disproven, even if that possibility is *extremely* minute, hence, cannot really be called a truth). And there is also approximation, which is a necessity in any scientific field.

Every time I hear 'urine is sterile' I just want to scream. It's a bodily fluid. There cannot be any such thing as a sterile bodily fluid. The fact that we taught doctors this incredibly faulty concept and so many didn't catch on to 'hey wait, how the heck can a bodily fluid be STERILE, there are no conditions inside the human body that could create sterile conditions' is very distressing

The body goes to great lengths to preserve its health and sterility (cleanliness) is one of those methods. Since urine has traveled inside the vascular system it is highly likely to be as clean as our general health allows. It's the gastric system that carries the poisons out, even nicotine. Urine is clean enough to drink usually, but not recommended.

Urine is how our body gets rid of waste products filtered from our blood and the liquids we drink, isn't it? That's how drug tests work (from my limited understanding of them anyway). So how can waste products that our body is so obviously getting rid of ever be sterile? Like, it's common sense, how could someone not have researched this better before teaching it to doctors and everyone else?

Isn't sterile, it may not contain major pathogens in healthy individuals but is far from sterile. When urine is checked under a microscope you can see a wide ecosystem of microbes. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside. Talking specifically about the urogenital system, it appears to have a microbiota. So why when we need to have a urine tests it says that there's no bacteria or pathogens? It appears that common culture methods do not detect many kinds of bacteria and other microorganisms that are normally present. when a person needs a standard clinical microbiological culture (there's various methods) to detect bacteria in urine because a urinary tract infection is suspended, or it needs to be ruled out, it's common for these tests to show no bacteria present. In 2017, sequencing methods were used to identify these microorganisms to determine if there are differences in microbiota between people with urinary tract problems and those who are healthy. They needed to assess the microbiome of the bladder, so they collected the urine straight from the bladder with a catheter. In the samples where the person needs to pee in a jar, the tests will analyse the microbiome of the urinary system and external genitals. (Little source for just 1 of the references used to answer the question right: Drake MJ, Morris N, Apostolidis A, Rahnama'i MS, Marchesi JR (April 2017). "The urinary microbiome and its contribution to lower urinary tract symptoms; ICI-RS 2015". Neurourology and Urodynamics.)

Proprioception is definitely underappreciated. We take this for granted because it feels logical that we can feel and know our body. Remember in school we were taught an experiment about depth perception, by closing one eye, pencil in each hand, and try to touch the tip together? Some may find it difficult. But if you repeat it with just your finger tips, you can actually do it with both eyes closed. It is not until you have proprioception taken away (temporarily, hopefully) that you realise how important this sense is. I had undergone some treatment with a medicine that have some anesthetic effect. It would not knock you out completely, but it would distort a lot of your senses for a few hours. One thing that it will take away is proprioception. You can still feel things with your skin without problem, albeit slightly numbed from the anesthetic effect. I can touch and feel the texture of the seat, I can shift my leg and feel the pressure of the cushion. I can even feel itch on my skin. Itchiness is problematic, however, if I need to scratch, say, the back of my neck. I usually close my eyes because the sense of balance is messed up as well. I can lift my arm, but I can't exactly tell how far have I lifted it, and how far my hands are from my face or my forehead. I have hit myself quite a number of times because of this. I cannot tell beforehand where my finger would land, so often I did not scratch the right place on the first try. I have to first touch the skin to know where my finger landed, and then move it towards the itch.

Fun fact regarding the blue yellow thing for dogs, a friend of mom's has a bichon, and the first time i met the dog she Hated My Guts. Just. utterly terrified of me. After a bit of experimentation with Hats, it turned out it's because my hair is blue, one of the two colors she can see clearest and NOT the one she would expect in that region of my body. It was a hilarious afternoon

There are two things that, had I been taught them in my K-12 schooling, it would have been immensely helpful in me understanding space. 1. There is no up or down in space. 2. The lack of gravity that seems to occur on the ISS is caused by them continually "falling" around the earth, not by the absence of gravity. If those things were taught, I think it would help decrease the number of flat earthers.

Correct title: 5 Things You Were Taught in Elementary School at an Age-Appropriate Level of Complexity For example, the "orbital" model of electrons may not be the most true-to-life model, but it is still accurate *with respect to* its general domain of relevance -- that being atoms, molecule formation, ion formation, etc. And it's good for illustrating certain aspects of chemistry at a certain level of abstraction, appropriate to a certain level of background -- namely high school and early college students. Those who specialize, of course, will want to eventually move onto more sophisticated models, such as "electron clouds", etc.

I also know from experience that despite what people keep saying cats are not color blind. One of my cats loved the color red. Anything red small enough for her to carry away got hidden in a pile behind the couch, but only red items. Even from a huge pile of Lego pieces she would pick out red parts and ignore all the other colors.

Cats are colour-blind in much the same way dogs are. Not being able to see the true colour of an object doesn't mean the object becomes invisible. Colour-blind animals, just like colour-blind people, can still tell most colours apart, they just see those colours differently. Cats can see teal, blue, purple, and yellow well (albeit with less intensity than most humans), but can't see green or red like us. Your cat's favourite legos were, to her, what you would call brown, which is a perfectly reasonable favourite colour in my opinion.

I am a MLS student and have rotated through a hospital microbiology lab. Doctors constantly order urine cultures even if the patient has no symptoms or only vague symptoms, particularly in hospital and nursing home populations. Most specimens are what we call "clean catch" which is when theoretically we have the patient cleanse the area with wipes and then pee a *little* bit into the toilet before catching with the cup. However, in actuality most patients don't do this (partially because no one tells them and partially because no one is watching so they tend to cut corners). The area, especially in women, is also teeming with normal flora including things like E. coli that are part of the GI tract. Every culture also costs $$ and many insurance companies (and medicaid/medicare) will draw the line on unnecessary cultures and refuse to pay leaving the patient on the hook for thousands. Some urine specimens are not clean catch. Some are collected from an indwelling catherter or even aspirated from the patient's bladder. With these, the threshold for calling a positive culture are lower. Also if a patient is being treated with antibiotics, the antibiotic can be filtered by the kidneys and excreted out through the urine so when we incoluate the plate with the urine the antibiotic just kills the bacteria, but we can see bacteria if we do direct observation. All of this is why when the lab releases a result there is a comment that tells the doctor that the result may not match with the patient presentation.

(*General Practitioners*) These were: "CSU" = 'central stream urine'. 💙 "MSU" = 'mid stream urine'. 🧡 In each case the instructions were to just "pee, pause, clean the area, pee & collect the 'sample' / 'specimen', & finish peeing" ! It's a practice I continue if asked for a urine "sample" ...though I haven't been asked to do so, so have no idea if it has ever been a useful habit since I first learned about it "back in the day" (1980).

I realize that your intended audience is Millennial & younger, but I found myself trying to recall when *I* first heard (school, not TV show) some of this stuff. Bear in mind I graduated high school around 1980. "Weightless" astronauts were the Apollo program. Weightless space station was a scifi coloring book I had in grade school. (The little girls spacesuit had a skirt!) Atoms were in scifi novels thru grade school. I knew they were *real* because of the concern about the Atom Bomb (movies on TV); but the first *discussion* in school about the reality of atoms was sometime in middle school; & the first diagram (traditional symbol) was Mrs B (coz we uniformly mispronounced her name as Boogerman), our high school science teacher. Quantum mechanics was speculative scifi in college (1980s). Sterile urine = TV only, in high school. High school science was mostly me effing up simple chemistry (due to undiagnosed mental illness.) My *only* HS science memory besides Mrs B & having an unhelpful lab partner! Animals in middle school = Koko, the gorilla taught sign language; & chimps teaching us how they think via sign language. This was a big thing in the 70s. Dogs seeing only black&white? Neighborhood, not school. First suggestion of more than 5 senses was in a textbook in high school. I doubt it was more than barely mentioned. What I knew was from reading the section in the book, because I was interested!

As a former science teacher I have two takes on this. First, middle school science teachers have to spend a lot of time undoing misconceptions kids were taught by elementary teachers who were not actually science people. (No, kids, the earth is NOT closer to the sun in the winter, I don't care if you liked Ms. Smith and don't so much like me. She was wrong about that!) But at the same time there are concepts that are just too complex to get into detail at the age that they are introduced. The structure of atoms being cloud with patterns where you might find the electron if you measure it but.... No, that's not from elementary school. I have the same issue with those who are critical of the way that we teach history. Using urine on wounds didn't come from elementary school, it came from a "Friends" episode.

@@Allan_son where the hell is that logic from? You were taught that WRONGLY by teachers no doubt. (The most common alternatives are INCORRECTLY or BADLY.) Do you write "Things you were taught incorrect" or "Things you were taught bad"?

As usual, I loved everything about this video, but the intro where you specifically addressed science teachers was a really nice touch.

In the library, all the science fiction books had a sticker on the spine with a diagram of an atom with a rocket ship piercing the nucleus. I have many positive memories of searching the YA section for "atomic/outer space" books.

Great video! Love information, & it's good to clear up misinformation! I hadn't even thought of "feeling temperature" or where we are in spaces as senses! Thanks for uploading!

Where we are is something our brain figures out from other senses and memory . It gets unpleasant when senses disagree like if a big animal picks us up or we are in something that moves . Temperature is part of touch, just like color is part of sight .

In grade school they taught me that the human genome has 28 chromosomes. Also that rockets could never reach escape velocity.

The first 2 while "wrong" are really just nice oversimplifications. They get the point across and help introduce the concepts.

We were trained in school to avoid finding answers in notes or other sources and not to ask anyone for help finding answers, because that is cheating. Instead of doing whatever it takes to find the answers you need in order to complete your tasks, which at work, is what they want you to do. Would you boss rather you memorize a few things and do lots of things wrong, or openly have conversations with everyone in order to always have access to the right way to do things and never do things the wrong way? I am assuming that the problem with school sucking, is that they can't allow you to only learn interesting and useful stuff because the teachers would have to do a ton of research to verify if each students work was correct or wrong. It would be a dream if you could choose to base all your classes on things you are interested in. Such as "you like bugs? okay, all your classes will relate to bugs in some way, history, math, science, vocabulary/spelling/english, etc." For someone who likes bugs, it would be far more motivating to learn about the history of bugs, rather than the history some some humans they don't care about. I would rather learn to spell scientific names for bugs like "Hermetia illucens", rather than words like "lugubrious".

I once had a some sort of infection in my inner ear causing my sense of balance going haywire. It was a clear case of one half of brain controlling one ear and the other half the other. It was way worse than ordinary dizziness: one half of your brain tells you that "down" is where it clearly is, and other half telling you that "down" is moving really fast to the right. What makes things even worse is that my eye in that "wrong" side tried to follow that information. Left eye looks forward, right goes to right. I could move only on all fours and eyes closed and only if I really concentrate on one side of the information only. Luckily it didn't last long. But it is a sense, and a strong one indeed. Not one of the five

I'm old (45) and even I saw the electron cloud model in school. (We also learned about the shells, because you really have to to understand chemistry.) We also learned ABOUT the plum-pudding model.

Wow I think I have watched most of these original videos over the years. Scishow is still kicking strong!

Apparently, dogs also have uniformly blurry vision? 14:44 From the information in other videos, dogs have 20/80 vision, so the person and dog in the photo should be in focus while the distant trees should be almost unrecognizable.

Always interesting, thank you.

​@@Mike_Jones281 Wait... what? Was this in a region where young Earth creationist circles were/are common? It's such a massive contrast to what Catholic leaders teach regarding science and the Bible that I've never encountered that sort of anti-scientific, anti-rational idea from any Catholics let alone Catholic teachers. I'm curious how that can even happen and sorry even if it was a single teacher with an idiosyncratic worldview. There is hope with other teachers/schools: Come college, we Catholic school students were the ones who understood the theory of evolution at the appropriate level. Our public school classmates didn't have anywhere near as good a grounding.

My experience predates the issues raised in this video. I remember being taught that you can't subtract a large number from a smaller number. And then several years later I learnt about negative numbers. Why the lies?

Bold of you to assume that I actually listened in school.

I believe that the sentence "every object in the universe attracts every other object in the universe" is wrong. I am not sure, but this would violate the speed of light, where nothing can go as fast as it (other than space itself) and since the universe is expanding there are objects that are moving away from us faster than the speed of light and those objects do not exert any force over us.

Space itself may be expanding faster than light, but no, objects are not moving away from each other faster than light. Google up "Lorentz" and follow through from there.
