Hello Miss Florence,

It was a very learning post about mass. It was also fun watching how the women explaned. With this post I lernt a lot.

Hi Florence
It was incredible to see that the mass was the same but in the water it went down. Then when magically the scale of the digital balance went up WOW.
Thank you
sorry i was to late on the other posts

I didnt know that if tou put something that is the same weight it ways more in water. I think its because different material has a different amount of upthrust.

Woww i learnt a lot she put some masess of different sizes but with the same weight she put those objects on scale balance and add some water and it seem that one of that masess had change but it didnt weight is the force of gravety on an object a force of 10 newtons going ddown on the mass but on the water there is another force acting too!
By bye see you tomorrow!

Hello Miss Florence,
for me is upthrust because when the girl put the two things on top the two pan balance the two were at the same level but when they put water in the glass one went up and one went down because upthrust.

HI Miss Florence!
Cool! Nice video. It talks about the Upthrust altering the weight put on the balance. Really interesting...

Hello Miss Florence!!

Amazing video!! Now I now more about the force of UP THRUST!! Its incredible, the smaller mass weights thet same as the big mass! Sometimes things can be super!!

Hi Miss Florance

I watched the video, it was very intresting. A blond eoman expert talked about 2 different shaped objects but with the same weight. She put them on a two-pan balance, then she put one inside water and the other one outside the water. The one under water, it´s pan went down, but the weight hadn´t changed.
She explained that the wight of an object doesn´t change though it is in air or in water. She said that what was going on was that wight is the force of gravity on an object, a force of 10 newtons. But in water it was with a pull of 10 newtons downwards to the center of earth and then it had upthrust in the opposite direction.

Nice Video, very intresting.

Hi Miss Florence,
This was great, to see that the mass is the same in two different places but in the water it goes down. According to what it said on the folder of upthrust, it is what makes a piece of wood stay floating in the water, such as the question in the class which says why does a boat, if it's so heavy, can float on the water.

Wow!!, the mases are of the same weight until the girl put water at the sides of the balance where they are comprovation that there are of the same weight even dough one is bigger than the another one,and the gravity with 10 newtons more pulls down one of the mases, and the other won stays ap words because of the force called upthrust!

at first I didnt understand nothing, it is so wierd, i thought that the wheight that sunk, did so because some water got in it or something like that, but it was all the other way, the upthrust got the other weight elevated. the universe is wierd...

Hi Miss Florence
I didn't undesrtand the first part but when she spoke of the mass that she had two kind of rocks in her hand that were of different size but of same weight and she put the in the balance and they were the ame but when water was added on went down and the other went down I think thats becasue of upthrust force.

hello miss Florence

I think that this video was very fun
here I pased you my observations and conclutions
observations:
Without air the cylinder weights more
with water the weight is less because to the forces of gravity their is an other force floating the mass opposed to the next one:upthrust
conclusions:
I think that the different size but same weight of the object in water,floats depending in air inside the object

I learned a lot with this video. The women explained it very well. I think that when she took the air from the water the spaces were there was air had to be filled with something and that is water that is heavier than the air.

Hi Miss Florence!
The video was great!!! It was clear but I couldn’t understand it very well because I don’t understand basically what up thrust does. The first part about the balance that the number changed that I couldn’t understand. And in the second part, if the two stones have the same mass and the both are in the water why is that only one goes to the bottom. It’s like it hasn’t any sence

It was amazing to see that the mass of both objects weight the same without water but when they are in water one goes down in the balance. Maybe different sizes and materials have different amounts off upthrust.

Hi Florence,
I enjoyed the video.
I learned that two weights might look very diffrent but the mass is the same.Also I learned that when you put both weights in the balance even though they look are the same the one that is under the water works diffrently because 2 forces work on it gravity and upthrust.

Hello Mrs Florence!
The video is awesome and it is incrdible how two different objects that weight the same, one is sank and the other isn´t in water. I didn´t understand why in the balance one of the object was sank and the other not in the water, I can´t understand how upsthrust worked there.

When you put two masses of the same weight in a balance they are in the same height becuause their weight is the same.But when they put water and one was lower in height because the water was not filled up to the top so as water weighs a lot the one that was absolutely under water was a the bottom of the balance.
Weight is the force of gravity on an object, a force of 10 newtons pulling down on a 1kg. mass. Under water there is another force pulling too, the water pushes up with the 1kg. mass, this is a force called upthrust.

Its unbelievable when the women puts the balance and the two masses are compared!

Hi Miss Florence,
I can´t believe that when two objects have te same weight but different sizes it keeps balanced. Because its in the air and weight is the force of gravity. But in the water gravity pulls it down but at the same time it goes up. And in the video said that it was called upthrust.

Hi Miss Florence,
The video was very interesting. First it surprised me that both objects weight the same, and then, than one sank and the other one no. The one that didn´t sank it was because the newtons were pulling to the centre of the earth at 10 newtons per Kilogram, but a force called Upthrust push it upwards with more force than the force that pulled downwards.

Hello Florenc,
It was incredible this video.
It looked impossible how can a mass of smaller size would weight more than a bigger mass in water, It is because newton is how many force pulls down an object by gravity,That force is the same in water than in air but as one is in water and water has another force called uphtrust that goes against gravity so the uphtrust makes the newtons lighter.
