Students: *losing their minds* Prof: “yeah not the best demonstration”

One of the things i loved about scuba diving is that you can see and feel the thermocline even to the point of being able to dip your fingers into the colder water or reach your arm up into the warm water

The fact that this demonstration was good enough to make someone unironically use the term "awesome-sauce" speaks to how well done this was.

Having a teacher who makes learning fun is the absolute best

"yo, why is this awesomesauce?"

The world's largest (known) waterfall/cascade is a cold water layer flowing like this, moving south along the floor of the north Atlantic, and falling over the edge of a continental shelf.

A single demonstration like this would have changed my entire attitude towards school

This is hands-down the BEST way to demonstrate the 2nd Law of Thermodynamics to anyone, ever.

This seems like a great teacher. The kids seem very engaged (at least for the video). I had a few science teachers like this and learned so much from them.

That girl was hyping this up and the prof somehow sounded like he was trying to downplay how cool it was 😂

British narrator: "While most aquatic species thrive in the red Gatoraid, the deep sea creatures survive in the crushing pressures of the blue Gatoraid."

This is one of the best ways to teach students that are visual learners. Props to this teacher.

Don't sell it short. It's a great demo.

I was a sonar tech in the Navy on submarines. We use these layers in the ocean to hide the sub in from bring detected. Sound travels differently in warm water than it does cold water.

Dude that one guy that said "this is awesome sauce" proves that we are prospering in science and education.

Most productive thing I’ve seen on social media today.

As a visual learner, mad respect to teachers who go out of the way to teach like this ❤

These are the best teachers. the ones who teach you and then SHOW you. I loved my chemistry teacher in high school because we did some of the coolest experiments

If students at school were this interested, teaching would be so much actual fun

"Don't all just get excited at once." He tried to control their reaction lol.

If you're diving in the cenotes of the Yucatan peninsula, a fresh water cave system, you will sometimes be crossing the barrier between the fresh water and the heavier and colder salty ground water and in some places, you can swim with your eyes just in line with this barrier. Then you will actually see those waves on the surface of the lower layer, illuminated by the blue light of your torch. That is a magical experience.

I love simple high school level science experiments. They are usually basic enough to help people understand the simplest things in the world that people take for granted.

I adore teachers who love to teach. You are unsung heroes.

I love that Hannah is doing the outros as well now. She is a fantastic co-host. Intelligent, well-spoken, and a critical thinker.

Reminds me of my chem teacher he loved demonstrations like this, every Friday was Fire Friday and it was an absolute blast

Cooblestone generator in real life???? 🥶🥶🥶🥶

This is why I love science! It's always fascinating, and teachers like him make a difference in the world.

Why was I today years old? I feel I should have been taught this. This could save a life in the ocean.

"Not the best demo" Literally the best demo you've ever seen

Teachers can make or break you. You sir, seem like an awesome teacher. I love when they are engaged with the students and let them be involved. It makes the world of a difference!

The very first whoa!, so funny.. the guy thought that the water all becoming 1 equal height after the barrier was removed was the interesting part. Never seen water before, huh. I'm glad everyone else waited to be amazed until you could see the clear separation, after it settled.

Man just explained how SpongeBob has water under water.

And this is how you do science. A practical demonstration, visually distinct features, audience participation. Thank you for being an engaging teacher. I know it takes more effort, but it's excellent!

The guys initial reaction... Like nothing had happened other than the water levelling out and he loses his mind, lol

It's called a thermocline, and happens because cold water is heavier than warm water. Having fished the Great Lakes for 50 years, we look for the various (continuous) bands of water that each species prefer. An "upwelling" can occur if a heavy, sustained wind pushes the top water towards shore and forces it to "turn over" and push it offshore. During the summer, when this happens, while downrigging, we often move closer to shore and sometimes find the species in very shallow water, where just days before they were out over hundreds of feet of water many feet down.

A young person looking at science that occurs in their world and saying "wait this is actually awesome" ❤️❤️❤️ love! So pure and cute!

I had one science teacher like this in my whole school career. Still remember Ms. Sullivan! She was so cool, made me feel excited for class, and did fun experiments like this! Love it!

Superb teaching method. I wish had teachers like him during my high school years. You're clearly invested in your students. Hopefully the school admin staff and the parents of these kids appreciate it. 👍

Bruh, the fact that the students got “amazed” at the simple concept of gravity is insane lol

I liked the part where people said "WOAH!" before anything happened yet. Bright minded students. Clearly excited about being excited.

The best thing is when you dive though that; it gets "misty" and really hard to focus, then when you're though the top layer, it very clear! We have this around the cost of Sweden, and it's most noticeable at the spring, but at deeper places, you find it in the summer too!

Lmao the "woah!" before the important bit has even happened yet

For those who dont know, This is density and temperature. Like Cold Water will sink while Warm Water will rise. The density is those with Higher Density will sink while Those with lower density will rise

Thermoclines can happen in all salt water. I have dove off of OC Maryland and above the thermocline is 80 degree water, below was usually 45 degrees. Going through division was like getting hit by a truck, even wearing a drysuit it was a brutal experience.

Oh wow so this is why the ocean feels warmer when you first get in, because the top layer is heated from the sun, then it gets colder the deeper you swim out because the warmer water only sits on top 🤯✨

Students: *whooooohhh, OMG* Professor: *We need a bigger tank*

Students learning what a thermocline is. When lakes are calm for long enough they have warm water sitting on cool water just like this. If you can find the depth of it you can use it to help catch fish

If you spend enough time in the ocean you can experience this in sensations of touch. When it rains hard you can feel the difference of the layer of fresh rain water sitting on top of the salt water. I am in the tropics so the fresh water feels colder than the salt water.

I love science. Doing experiments and demonstrations were the best in bio, physics, and chemistry. If scientist as a career was explained to me as a kid, I probably would have chose that path

So that's the reason why the shore is sometimes cold at the bottom, gives me chills when I feel it 🥶

I am even more surprised that grown ups are getting awed by this ..... we learnt it in school .....

Thermo and halocline demonstration! Sometimes you can see and feel the layers when you're scuba diving! ❤😊

Such a chill teacher from the sounds of it, seems like a good class to be in

🙌🏻 SUPER COOL to see the cool water go to the bottom!! Wow. Loved this!! 🎉

Science teachers are always the ones with the best personalities. Probably makes sense since we'd want to inspire more students to go into these types of fields upon graduation.

Great job helping us visualize a thermocline ( separation between different layers of water). I used to go skiing at the lake and I loved diving down and feeling the cooler water after a hot day in the summer water skiing.

Everyone i know always asks me how i can remember so much stuff from high school and its because of teachers like this.

Shows the most basic physical principal: "No waaay --- This is craaazyyy!" 💀

In the words of ChubbyEmu: “Where there’s salt, water will flow to it.”

I always knew spongebob was a scientifically accurate show

I love underwater lakes

Seeing different levels of water is so fascinating, especially when you're younger, you mainly learn about water and oil, you never thing that the water itself can be separated like this. In the ocean, theres something called brine pools, water containing 8 times more the amount of salt than the surrounding water causing it to sink, because of the higher density. It sends creatures that enter it into toxic shock, and many die, and some eels will use these pools to scavenge, risking dying themselves.

Props to the teacher for finding an engaging way to learn them there stoodents. Get This Man A Raise! For real, pay the teachers better, please.

Fun additional fact: water is most dense at 4C. As it approaches freezing point, it starts to become less dense.

"yo that's awesome sauce" -that one kid

I love this experiment

The person who made that “woahhhh” sound was 100% moistcritical

If you walk deep enough into the ocean in some places you can actually feel the shelf and the current between the layers. it's really cool!

Great teaching. It is always fascinating to see physics in action. I used to do little experiments like that when I was 10 yrs old. Drove my parents crazy…

Seeing it with your own eyes so completely changes gow you understand things. A very good way of teaching.

leave it to a professor to say "meh, it's not the best demonstration" after making the whole room go "WHOOOAAAAA"

This is a really great way of explaining brine pools!

I miss oceanography, was my favorite class ever in senior year.

Tank: Dude: WOAH Tank: Does the thing

I would always feel this as a child swimming in the ocean. There are cold spots underwater! But it’s more like 1 small spot, not the entire ocean floor

Aww man, makes me think of my science teacher, he was the best. Wonder what hes doing now, thanks Mr.Turner, your lessons were some of the best

I see informative content, I like & sub.

I used to be a submariner, this was very evident as you went past a large river estuary. It could be quite dangerous as the boat would either suddenly float or sink depending on the layer you were in.

This is also how a hot water cylinder works. Great visualisation.

"WOAH! OH MY GOSH!" before anything even happened... You can learn this easily, yourself, by diving deep into a lake during the summer.

Good teacher. Making intrigue in understanding.

What's more interesting is how cold water mixes with warm saltwater.

when you get into the pool thinking it’s gonna be warm and nice but as soon as you hit that temp barrier your tootsies are freezing

Professor visually showing students a thermocline. Nicely done

did you make or order this?

I find it fascinating how much smaller the volume of the cold water appears despite it seeming like there's the same amount of each

Love how when they barely pull the last board up, and before anything happens, the water just levels out, as you would expect, and all the kids are like “whooaaaaa” lol professor was like guys nothing happened yet

Now you gotta put the dividers back so we can part the Red Sea 😂 Fr tho, cool demo :D

Good job, teach!

Density stratification. Was waiting for him to explain this more lol. Basically the denisty of water is effected by temperature and salinity. As a result, water with lower salinity or higher temperature will float on top of water with higher salinity or lower temperature. The layers of stratified water can have different properties that change rapidly with depth, which are called "clines". For example, the thermocline is where temperature changes quickly, the halocline is where salinity changes quickly, and the pycnocline is where density changes rapidly. There may also be regions where there is no change with depth, which are called mixed layers. Even more intriguing is sea mammals adapt to the environment based on the density of water. Or these clines.

That's exactly what happens in Milford sound in New Zealand. Its were i grew up a a kid. A glacier carved out a deep fiord. The trees grow on the side of the mountain as the rain water goes down the mountain side were i sits on top of the saltwater. There's a big mound of rocks at the mouth of it. Which breaks the oceans undercurrent so the fresh water sits on top of the salt water. The fresh water picks up dies and tannes and creates a dark layer of fresh water. Tricking the fish and sea life to think its deeper it is. There's a very rare deep sea coral that grows there near the surface. Its called black coral and only grows like cm every year.

Excellent explanation on how warm and cold water don't easily mix! It's fascinating to consider that this isn’t the first time our planet has seen massive influxes of warm freshwater into colder oceans. At the end of the Ice Age, as glaciers rapidly melted, similar events occurred and had significant impacts on marine life and ocean currents. These changes were so dramatic that they likely contributed to major shifts in climate and ecosystems, which are echoed in many of the myths and legends passed down through generations. This historical perspective not only highlights the power of natural climate events but also serves as a reminder of the potential scale and impact of current climate changes. It's a sobering thought that what we're observing now could have equally profound effects on our planet's future. I truly hope people get away from religion in time to stop fighting reastional thought, and we vecome a more scunce and logic based society, at least in america. Im tired of feeling like a immoral christian nation that cares more about colonization than science. 😅

Nature is cool 😊

The experiment is really cool but The student reacting when nothing happened yet gets me 😂 he’s so interested he swears

"not the best demo" I'm 30 years old and I was watching like a damn kid again 😂😂😂

40 years as a limnologist, great demo.

This should be an exercise every science class shows the students

experiment: nothing happens yet students: WHOOOOOOAH NO WAYYYYYYY

The Romans used this to have heated pools in the bath house. There was a slope so that the cold water would constantly go down to the wall with the heater attached to it and once it was hot enough it would rose up the slope and it would continue cycling that way to maintain constant and even heat in the pools/baths

This is the stuff that I lived for as a kid! Hands-on experiments were so much fun. Unlike boring old regular school paperwork.
