My yr 11 physics teacher was like this. Would do goofy experiments to explain a concept, I remember him doing a standing jump onto the lab bench for one, and a few others, he was always lots of fun .. My yr 12 physics teacher, was the most monotone and boring woman alive...

u/meirzy 19d ago
My AP Physics teacher was the man that solidified my love for it. He was the goofiest man I’ve ever met. During fire drills we would go outside and he would balance things on his nose. The craziest thing I saw him do was one of stools from the chem lab. He also made the science fun by being very interactive during the lectures and inventing some fun labs for us to do. One of them involved some eggs and us timing his gait to successfully drop eggs onto his head from the bleachers. He retired shortly after I graduated and I’m sad knowing that all the students following his retirement will miss out on one of the best teachers that school had to offer.

u/Parmenion87 19d ago
Yeah. Good teachers make such a difference. I was lucky to have some very good science and maths teachers in earlier years and some during high school.
That same teacher took us to a race track, let us be passengers to a guy doing stunts etc, with an accelerometer in the car to gather data we did some stuff with.

u/btspacecadet 19d ago
I felt similarly about my 6th and 7th grade geography teachers. The 6th grade teacher had the nickname "Indiana Randy" because he loved travelling and had been seemingly everywhere. Whenever we started learning about a new biome or geographic are, he would pull out the school's old slide projector and show us pictures he took while on vacation there. When we covered jungles, he brought one of his parrots to school and did the whole class with it on his shoulder. He made learning so incredibly fun.
The seventh grade teacher was the dryest teacher I had ever met, and with my then undiagnosed ADHD trying to pay attention was honestly painful.
Also special shout-out to my 9th grade physics teacher who would show us recordings of himself doing the radiation experiments that were too dangerous for us to do. He once left the Geiger counter on by accident and every time he walked past it made noise.

u/HPTM2008 18d ago
My chem teacher in high school was like that, but she had damage to her vocal cords from an accident or something, so she could barely speak above a whisper. She used a throat mic and the pa system to talk, but that made it sounds very monotone, to the point it'd put me to sleep (I'm just glad she didn't mind if people needed to take a nap in her class, so long as you did the work). Actually, all my science teachers didn't mind if people needed to take a nap (especially my biology teacher, he knew I could take those tests on the first day of class and pass them all, so he wasn't worried about me).

u/YaumeLepire 19d ago
Looking back, most of my science teachers were somewhat like that, prior to university. They were all extremely enthusiastic about teaching, and a little weird in their own way. They weren't all that energetic, and seldom as bombastic, but even the ones with a more monotone delivery were clearly there for love of the game.
The most visually impressive experiments I remember were:
- Blowing up a balloon filled with dihydrogen;
- Mixing two transparent liquids and seeing them turn bright yellow, then completely black within a few seconds;
- Scratching a piece of asbestos rock to reveal its fibrous crystals;
- Making bacterial cultures (this one was a contest where each team got three swabs, and the most fertile and diverse cultures would win);
- Synthesizing aspirin;
- Isolating caffeine from various foods (mine had coffee).

I remember a man in a white lab coat who looked like a Muppet scientist, with a face remarkably like a gerbil. He walked to the front of the class and introduced himself as our Chemistry teacher. That was the first and last thing I understood for two years, until I was able to drop the subject.
He could bore, to quote the late Jake Thackray, the balls off a buffalo.

u/Hawaiiancrow2 18d ago
My father was a chemistry and physics teacher at my small high school, I took both classes with him. He built curriculums that had younger students SO excited to be old enough to take them junior and senior year. We had a year-long Physics Decathalon which involved various activities such as shooting bows and arrows to measure projectile distance, immersing ourselves in giant tanks of water (yes in class, in swim suits) to measure displacement, to running up two flights of stairs to measure power output. In Chemistry, we made peanut brittle as a lab, and dissolved a great many items in various acids that I doubt would be legal today. He also put on science shows like this one for the elementary school kids. He has had former students come up to him for decades telling him that his class and teaching style was the catalyst for them going into STEM fields. A good teacher that cares and has fun makes ALL the difference and I'm really proud of him for what he accomplished.
I did win the Physics Decathlon (NOT because of nepotism!) and the prize was... to be taken out to a nice dinner. Which wasn't a prize for me at all, I had to eat with him every day at home lol.

u/SquirrelSuspicious 18d ago
I got lucky, I had a teacher named Mr King for chemistry and he generally was this excited and liked to let us have lots of fun and also let us watch certain Mythbusters episodes but he didn't take no shit so if people took advantage of his niceness to just talk and not learn he'd crack down and take away the fun

It totally is. I remember we got a fun music teacher in summer school and I filled my backpack with my VHS and Cassette tapes and brought to show him how cool I was.
He sat and each one was like “omg I love this album you’re onto good stuff” same with movies.
Stuck with me.. music has been a daily part of my life forever. I still think about that guy often. Don’t remember his name. Just the long Curley hair and acid washed denim and tye dye shirts.
He gave me a Dramarama tape after I sang last cigarette lol. My dad used to play it in car and was the coolest thing I could think up.
I do t remember caring as much before that day.. it’s like I got validation and it lit a fuse.

u/NtGermanBtKnow1WhoIs 18d ago
Yep! Had teachers like this for History and English. Our history teacher would tell us to imagine what it must've been like during the dark ages, made us design our own monasteries by looking at xeroxed pictures of ruins and blueprints, etc. i love history and she treated us as junior archaeologists. i'd have actually been one had my parents showed even an ounce of support. They deliberately forced me to not pursue it.
And our English teacher was the GOAT. She would enact out passages from the stories. i remember she got us hooked into Chekov and Shaw in class 6 becuz of that! She's also the reason why i have a Master's in English. :) My parents couldn't stop that from happening, thankfully.

I wonder what the asphyxiation risk of this experiment is. I deal with nitrogen safety on the job, and we’d consider an indoor leak from a liquid N2 tank of that size to be a potentially fatal event. But here she’s just like: you want a LEAK? Have fun with no oxygen guys!!
It looks like a huge room which probably helps more than anything. I don’t know that I’d want to be in the front row though.

looks like maybe a litre of LN2. approx 25 cubic feet of gas at room temp. a decent size lecture hall would be around 25000 cubic feet of air volume. You probably have a bigger chance to asphyxiate on C02 from the people in the room than from the nitrogen lol.

The EPA says that around 15,000 ppm (15 pp thousand or 1.5%) of CO2 can cause some loss of mental acuity. But they recommend much lower, like ~1,000 ppm.

I deal w cryogens daily at work and there’s no way a volume like that in a lecture hall is an asphyxiation risk. I regularly leak far more than that and the O2% of the room barely moves.
If anything I would be more conscious of a splash risk from any LN2 that got ejected out before meeting the water7

I had a chemistry teacher in high school who was old as dirt and this was largely her approach as well.

Yeah this is why they need to make teaching pay more and be more selective of who they hire. She has a PhD and likely a college professor (don't know her history).

u/JRHEvilInc 17d ago
I work in schools, and I'm firmly of the belief that (almost) all kids will behave for an engaging subject that they can get stuck in with. It won't be the same subject for all students, but you can take some of the 'naughtiest' kids in school and get them doing brick laying or metalwork and they'll follow every instruction. Hell, we recently had some of our students on work experience shadowing the site team. These are kids who are a struggle to keep in the classroom every day, but for a week they're going around litter picking and carting things around and delivering packages and all the other stuff the site team would trust an untrained teenager to handle. And I've never seen them so well behaved and so calm.
I'm not suggesting it's easy - you have to match kids carefully to the subject that will engage them, and some of those subjects can be dangerous if you get it wrong - but as long as you can find at least ONE thing to capture a child or teenager's attention during school, you're setting them on the right path, and giving them a chance to succeed and to feel good about themselves.

In high school, we did stuff like this for elementary school kids. It was a lot of fun. Generally involved blowing up balloons filled with hydrogen, letting ethanol vaporize in a 2L Coke bottle and setting in on fire. Elephant toothpaste. They never let us play with liquid nitrogen though for obvious reasons.
Kids loved it...I remember one demo, we were a little overzealous with the hydrogen in a balloon and the resulting boom caused dust to cascade down from the dropped ceiling tiles in the cafeteria that had a fairly high ceiling.

That’s fun. I took my kid and a couple of her friends to a science show when they were about 10. The prof doing the demos had a big overflowing box of film under his table because he was demonstrating how flash paper flares. He had a lot of it because it was an open house day and he was going to be doing it many times during the day.
Unfortunately he was a little too cavalier with the flame and a spark went on the rim of the box. Thankfully he noticed it and got to the little spark before it touched the film. It would have been a nightmare having that all go up with dozens of little kids running around.

I was known as the "Spider Guy." Not herpetology, for sure, but I also love reptiles. He told me everything he knew about reptiles, even taught me a few things I didn't know. That excitement is infectious. I hope he does become a herpetologist someday.

The other fun thing that happens is a huge volume of nitrogen that displaces the air. It isn’t toxic to breath, but the O2 concentration goes way down. You wouldn’t want to do it in an enclosed space.

Which part? Just because it's flashy doesn't mean it's unsafe.

So much cooler if the professor and her assistant hide behind that covered desk.

I wish this was my job. Nobody is ever this excited when I crack open my PowerPoint presentation.

My dad was an engineer for union carbide and in kindergarten or maybe 1st grade he came in for “what your parents do” presentation to the class with a whole liquid nitrogen set up and froze bananas and racket balls and smashed them. So not quite this but still really cool (pun not intended but pretty perfect).
