Hi Miss Florence!
I really liked the video!!!! I liked the way they explained things, it was clear enough for me to understand. It was funny the example of Ken and Kevin. I didn’t know that when the water had salt some forces change. In school the pool has salt, but it doesn’t happen what happens in the video.

It was amazing the swiming pool where that girl was floating. I would like to feel that experience of being in a swiming pool full of salt. I also was impreased when they put that toy on to different glasses because I could compare how it floated in one and how it sink in the other. I also like the part they show us the water that comes away of the glass and that was the same weight of the toy but in water with no salt the weigh is not the same.

Florence,
it was quite interesting, It is funny that they used ken as an example. But it was also interesting, i never knew that fresh water is lighter than salty water. But I don´t quite understand why was it impossible for her to swim.

Hi florence
Jaja how the girl drinked tea by floating in the water an how she realised about the sault of the water.
Kevin in a pool in a point the also flotated but in one point in a thing were fish live no because something had the weight of kevin
We also can now how Kevin through about some water of a beker if you put him inside how it through it to a another beaker

hi miss florence
this video is great
its amazing how the weight of kevin was equal to the water that was displaced to the beaker that was the upthrust force then needed for kevin to float how interesting
it was amazing how the cup of tea and the other things floated because of the saul in the pool

Hi Miss Florence

This video is about a lady who is swimming on a pool and a cup of tea pass floating on the water!! The cup of tea float because the water was full of salt(BRIME) and thats I think it produced more upthrust force. Then they show an experiment with Kevin that if they put it on fresh water the fresh water wins the upthrust force. The video was great thank for posting it.

Hi Miss Florance

This video was unbeliveable. I had never seen somethiung like that.

In the video a woman apears in a pool, which she explains it is imposible to swim there. She this was very unusual pool. Everything floats. Also she said it was good to have a cup of tea. The water in this pool has a remarkable effect it is extremly floaty.

What happens is that it has salt. After she left the pool in her skin there was salt. The pool was fool of salty water and that is called brian. It is more salty than the sea. This brian comes from a salty sea. It floats because there is upthrust which is exactly as it´s weight. Which thise forces are pulling in opposte directions. THIS IS SHOWNED WITH A TOY KEN.

If you put the ken in fresh water the ken will sink because the upthrust force is less than the weight of the toy. When oyu put an object in fresh water the object displayes the water and the water level increases. If you do the same in a beaer the same thing happens and you are posible to measure how many water does the object have displayed out of the beaker.

It is amazing to see that the volume of the water displayed is the exact same volume as Ken´s. The displayed water it is very important.

If you do the same with the salty water the amount of briant displayed by the object will be the same amount of brian he displays while floating, but it is less volume because not all the ken is on water, a part of him is under water. But the wight of this displayd brian equals the upthrust force.

I LEARNT AT SCINCE CLASS THAT THE MEANING OF FLOATING WAS PART OF THE ELEMENT ON WATER AND SOME DOWN, IF NOT IT WOULD BE SURFACE TENSION!!!!

I liked alot this video!!!

See you soon.

This video its showing again how the force of upthrust works. In one moment the girl shows that in water the upthrust has the same weight as the little toy soo it dosen´t sink, but when he put anothe toy in fresh water like the upthrust is less than the toy's weight it sinks!!.

Hi Florence:

I learnt a lot fromthis video and I think it was one of the best ones you showed us. The toy called Kevin could float on salad water and not on normal water that was amazing and was because in the salt water the brime pushes up at the exact force than his weight.

I loved that part and it was really amazing.

Hi mis florence, the video was very good i liked how they compared the things. the upthrust of brine equas kevin's weight. 2. in fresh water there is very little upthrust, thats why kevin sink. 3. displaced water is equal to kevins volume. it is very difficult to teach a person how to do the plancha in a pool because there is very little upthrust.

Hi Miss Florence
In this video the girl is showing how the force, upthurst work with salt and in normal water. The barbie boy was the one that shows the explanations! with salt in the water he stay floating, with normal water he went down (sink) upthurst, it seemed to be working more with water salt because it stay still.

Hello Miss Florence:

In this video a woman entered to a pool which had lot of salty water, this is called brime. In the example of Ken and Kevin, Ken dived into a pool with salty water were the upthrust was the same as his weight so he floated, but Kevin dived into a pool where upthrust was less than his weight so he sank. See you in class!!!

Hi miss Florence,
This video is wow, its a supper explanation of upthrust. I knew that water level risis when you add something(the example of the bathtab). But I didnt knew salt had more upthrust than water. I thoght when you float on water the upthrust was more than your weigh, but this video shows that the upthrust needed to make you float is more than your weght. But when you are swimming the tee does not fall?

Hi miss florence,
It was very intersting the expleanition about upthrust.
There is more upthrust in pools whit salt.But if im on one of those pools i wont put my head under water because of my eyes. I think when an object floats only the 10% you can see above water and the 90% is under water. It would be a very good experience to float on a pool.

That pool is filled with water AND salt, that is why the lady floats, and also why the cups of tea float.
it is also the upthrust pushing up. In normal water the upthrust is smaller than the other upthrust used with Ken, so he sinks.
When an object is emerged in water some water is thrown out of the way. The object displaced some water.
The displaced waters volume depends on which is your volume.
The upthrust in fresh water is less than his weight, so it sinks.

I really liked the video, it was very interesting and as I already said, Im very pleased with the examples given. I learnt that when you had water mixed with salt the forces were different. Now I understand why in the dead sea in Israel you float. I am very happy when learning science because then I can connect everything to everyday life. It was very interesting to see the examples of ken and kevin and when they were compared.

Hello Miss Florence,
I really loved this video, it explained really well.
I understood, when water has added some salt it is esear for objects that sink to float. The girl's example, it is incredible how she floats in such a way. But is is really diffrent that Ken and Kevin;s example, they are lots of times smaller but they float and sink. The example of how much water it displace. It was fun to watch the compares the girl did with Ken and Kevin.
It showed the same weight of the toy in water. But when the water has salt the weight is not the same. Ken and Kevin were funny example's. Fresh water is heavier than salty water. Why couldn't the girl swim?
I don't think it is a good idea to drink tea on the water, but the little table with the tea cup and more, floated. I couldn't imagen that there was saltier water that the one in the sea!!

Hi Miss Florence,
This video was incredible. This video was clear enogh so that we can all understand. The pool had salt so that you can float. The explantion of Ken and Kevin was really funny. If you have normal water an object can sink. Because it pulls it down but it goes up with less weight than the object. But if you have water with salt if floats because if pulls down but at the same time it goes up with the same weight.

It was very interesting the way Kevin floated on the Braine water which is the water with huge amount of salt.

Hi Miss Florence,
I learnt there is a very salty water is called Brain. The pool shown is fool of this salt. The brain comes from a nearby underground lake which is ten times saltier than the sea. The brain pushes up with an up thrust force exactly equal to his weight. In fresh water the up thrust is less than someones weight, so it sinks. When an object is emerst in water it pushes some water out of the way. The object displays some water.
