Nice improvement of a kitchen scale: kzread.info/dash/bejne/p2mnr8qBYNW3naQ.html

the density of the liquid was my first response.

Thank you for making this video. It really helped! 😃

what is the "other" liquid?? Since she said its flammable, I am assuming it was alcohol?

My guess is rubbing alcohol. I do the same thing with ice cubes....they float in water, sink in alcohol.

Teacher: *don't be condescending, don't be condescending* Teacher: immediately condescending

Thank you so much. I love to introduce concepts with discrepant events- very engaging. Is the liquid alcohol?

This is perfect!

Thanks great upload

good explaining

good teaching..

Please let me know which different solvent is added in in both? Please...

I'm just sitting there knowing she has rubbing alcohol the whole time in the other flask.

Not a clear explanation,confusing, only revolving around the subject. If you are teaching your students this way they are preparing to fail

It's okay if you thought the candles were different pieces, it takes time for people to learn, that is the fun part.

my son age 7 understood but got it wrong. we both thought it was because one was hot and the other was cold. we tried with 2 of the same balls in some cold water and they floated and then placed them in hot waster and they sunk. they kept sinking inside the hot water and also tried repositioning like you said in the video and they sunk a few times in the cold water. thank you for explaining your video. I understand clearly when I follow along.

May I just say that I understood this perfectly, and that not everyone learns the same way, and therefore even if you can't wrap your head around this by taking a step back, other people can, and shows people how they learn, so really, the only failure is on the end of the student who doesn't try.

BUT GOOD TEACHING I LOVE SCIENCE

Archimedes’ Principle. The buoyant force acting on a submerged body of mass = the weight of the displaced water. If the difference of the candle’s density and the contained liquid’s density goes to negative the candle will float. And if the difference of the candle’s density and the contained liquid’s density goes to positive the candle will sink.

I agree with Ken, I also think it's rubbing alcohol.

Love it, Thank you

Really, what was the flammable liquid?

Wow! Amazing ^_^

First thing that came to mind when she swapped between was that the left liquid was not water.

mam I like your teaching

What is the flammable liquid?

this one is based on archimedes principle

She looks like a fun teacher! Much better than most i've had.... I guess it's all about perspective and experience. Criticism comes from minds who have never taught= IE: they are more dense people. Lighten up and you'll float more through life ;-)

Such a great demo! But an awful explanation for the motion of these objects. All bodies accelerate due to imbalanced forces - in this case, the weight force and the buoyant force. While density is necessary to explain this behavior, density itself is not sufficient to do so.

This was a good lecture.... although you seem like a mean teacher :O

so compilicated

Ok Less dense object + Denser liquid (Water) = Object Floats Denser object + Less dense liquid (Oil) = Object Sinks

I'm triggered

I wish that helps me for real and I have a headache of science of d=m/v😅😅😅

spamming is awesome

It needs to be a bit more to the point, I think she put salt in the water

I bet students were confused during her class. She needs to improve her demo.

Things float because the weight of the size of the object weighs less than the weight of the size of the liquid it displaces... Roughly speaking.

@DivergentDroid

That's a good way to put it. I would call that anti gravity wouldn't you? You observe an object rise so there must be a force from the sky that's pulling the object up right? Of course that's silly but it's exactly what people believe when they say the ground has a force called gravity that pulls things down. There is no mass attracting mass, no space time. Gravity is the false but popular name we give to the downward effect of objects falling because they are heavier than the amount of medium they displace. Everything is always trying to get back to their natural state, equilibrium. Gravity, destroyed.

Not a good lesson. You gave the impression the liquids were the same. Science needs to be specific, not vague. A better display would be to have two different liquids of different colours to display their density. I'm sorry but your zeal to force kids to think will actually switch them off. Amaze them and they will think.

It's an amazing lesson. It gets them to question and think about things. It's teaching them it's not about the weight of the objects. It's not because one's heavier or lighter than another. Eg a tiny rock sinking in water but a huge ship floating on water, because its not about the weight. Its about the relative density. The objects density relative to the mediums density. Both candles were the same density but were not the same weight.

@@Rachie-nj3oi watch the video again. She quite clearly states that the liquid in both beakers is water. Then admits that they contain different liquids at the end. If they are led to believe that both beakers contain the same liquid how can they work out that it's the liquid's density that makes the difference. Also, aluminium used in the canning industry does not degrade in water.

As long as you immediately realized it is a human being, all is good.

As someone who knows this professionally, I love your enthusiasm! However when I try to watch your lesson objectively, I feel deceived. And it’s a fun deception, don’t get me wrong. But I think you’re putting the cart before the horse here with the lesson. You’re showing trick before the principal of the lesson (density). Which may seem deceptive and off putting (people like to be right with their guesses). So maybe next time try floating the candle pieces both in water, observe they both float. And then go to fill another flask with water, accidentally “drop” it below vision, and pick up your other flask that’s not water and then play your density depends on the object lesson. Just my humble suggestion. I did like the lesson a lot though!

Boooo

At the beginning she makes a big fuss of filling both containers with water. (She even tops the one which is not water with water from her jug). So how are her students to know that one container is not water. Very stupid and confusing way of teaching. No wonder she says her students don't understand what density means.
