this video actually helped me with my science homework. it explains well if not basic but well, and is formatted and made very well. awesome intro showing that this isnt a boring lesson of a teacher who drones on and on about ... well ... not the topic ( i have had too many of those teachers ).
Bro thank you for actually EXPLAINING TJE PRACTICAL INSTEAD OF JUST SAYING RANDOM SHIT AND EXPECTING 14 YEAR OLDS TO UNDERSTAND WHAT OSMOSIS IS INSTANTLY
I came here for the experiment, and i personally love the british accent. The word "water" said so many time, just bring this video to another level ^^
@@hilol5129 same here and I'm in secondary level education. I thought it would be easy to do an easy experiment like this but I was wrong. Not much things to talk about
my ap bio teacher told me for better accuracy use one potato for the strips because each potato has slighty different solute concentration and somewhat differs in the solvent of water therefore using one potato theoughout the entire process may lead to better accuracy in final results! :)
First we peel the potato we will also need 18 strips, we then needed to cut all the strips down to 6cm. Next we made our solution we needed, a sheet of paper on the balance. We had to wait tell it reached 1 gram, then we got 100 ml water to add to the salt. Then we poured the water in the beaker with the potato strips. The leave them for 20 mins after leaving them for 20 mins we had to measure them.
where the plotted line crosses the red line, at what salt concentration (in g/ml) would a potato be placed in for it to experience no change in length?
We just started a lab due to corona we are not able to perform the lab so we have tot watch this vid...I really don’t know what to write for the discussion.💀
Try writing about the lab a little definition of osmosis talks about it what happened to the potato why it happened due to the ph level it might help we all getting trouble relpy if it helps
Great video, ive got a question hopefully you can find the time to give your thoughts. Your experiment ran for 20 minutes, what do you think would happen if it went on for an hour? or maybe 1 day? In the case for higher salt concentrations, do you think eventually some of the water would go back in to the potato? or would this be just a one way thing? In cooking, there is a thing called a dry brine, where you add salt to lets say a steak, and leave it outside/fridge, at first water comes out of the steak onto the salt, but after more hours that salt liquid gets reabsorbed into the meat... i realize there are different factors, but im wondering if somehow in your experiment, there would be a time when the water could be reabsorbed into the potatoes
Movement of water via osmosis will occur until the water potential is equal inside and outside of the cells. This may take 5 minutes or 20 minutes or longer. Regardless, once this balance is reached there will be no further net movement of water. I don’t know how dry brine in cooking works so I can’t comment on that as a comparison to this experiment. I hope this helps.
My teacher wants me to find the concentration of sugar INSIDE the potato cells after going through osmosis. The answer must be in Moles. How do I figure this out ??? Please help
When there is no change, there is no net movement of water.Thus, the percentage of sugar in the solution is equal to the percentage of sugar in the vacuole of the potato cells.
No one gives an explanation for the potato getting softer in a more concentrated salt solution. Normally leaving objects (which can absorb water) in water and making them wet, makes them softer and more flexible along with increasing their volume. But here... ?! The water leaves the potato, so it's expected to become more dried and rigid.
Could extend and model animal cells on macroscopic scale with slugs. In pure water they'll swell and ultimately "explode" If placed in salt water, they'll shrink and shrivel up.
random commenter OK your teacher probably won't tell you this but make sure it isn't the same as the rest of the classes work. The examiners will give you 0 if you do.
Cells become larger when water enters them via osmosis which makes the potato strips longer. If water exits the cells via osmosis the strips become smaller.
i learned this in 5 minutes instead of spending hours reading a whole textbook
How did he find the change in length
@@Nevey2fye he measured it...
Thank u
Would've taken a min if you read the book

Thanks for answering my research question and literally everything what I need to include in my lab report about Osmosis!!!
Hi. Would you mind sending me a copy. I'd Iike to read it
so your're an ib student
Why can't school teach us like this
more bette than my teacher xD
school is making me literally do this right now
We are writing 5 pages of essay from a 5 minute video.amazing !

ikr ugh i had to compromise and over-exaggerate my lab report
So well explained. Observations like size changes make science cool. Comparison and scientific method.
my ap bio teacher told me for better accuracy use one potato for the strips because each potato has slighty different solute concentration and somewhat differs in the solvent of water therefore using one potato theoughout the entire process may lead to better accuracy in final results! :)
How does your AP bio teacher intend to get 18 strips from a single potato?
Science Sauce oh, the way we did the lab, we used one potato per test tube for 11 tubes in total!
First we peel the potato we will also need 18 strips, we then needed to cut all the strips down to 6cm. Next we made our solution we needed, a sheet of paper on the balance. We had to wait tell it reached 1 gram, then we got 100 ml water to add to the salt. Then we poured the water in the beaker with the potato strips. The leave them for 20 mins after leaving them for 20 mins we had to measure them.
Couldn't concentrate because of your awesome accent!!😭😭🥰🥰🥰🥰🙀
This makes sense! I'm feeling a bit more confident for my test tomorrow
Watched 4 videos before this one. Good job, I finally understood!!!!
you saved my life
this was amazing, your explaining is exceptional
Thanks!
@@Science_Sauce Its ok!
watching this coz I don't have a potato, plus it's lockdown in our area 😪
I need more vids about science, I can learn more from this than school
This was a very good explanation to understand, you made it very clear now, thanks for helping me with this!
This is soo useful better than my science teacher
This video is helping me explain turkey brining on Thanksgiving

Thank you so much for your vedio. It's really helpful for me to plan the experiment for my student.
You’re welcome!
What a time taken after put piece of potatoes into the beakers
Really helped me for my exam
where the plotted line crosses the red line, at what salt concentration (in g/ml) would a potato be placed in for it to experience no change in length?
Why did you ensure that all the potato strips were equal in size at the start of the experiment?
WELL CARRIED OUT + results at the end to go with it .. TQ and will certainly be helpful for my own students 😁👍🏻👍🏻

Great video, nice work 10/10
Great video, but you would have shown how to calculate the percentage and average change in length

This was outstanding so simple to understand
How do you get the change in length?
I just start this in school...
measure the length of the potato before and after the experiment using a ruler and then do final length minus the starting length to get the change
@@jomanaeldeek6993 thank u

In pure water they'll swell and ultimately "explode"
If placed in salt water, they'll shrink and shrivel up.

Martial Striker yeah my teacher said that today
random commenter OK good.
mupp
3:59 how. Do u get the change in length in percentage? Whats the formula? Thanks
( (final - initial) / initial ) x 100
Can the change be explained by the diffusion of salt across the membrane ? Why or why not?
In terms of the cells forming the potato strips why have the lengths of the strips changed in the way they have?
Cells become larger when water enters them via osmosis which makes the potato strips longer. If water exits the cells via osmosis the strips become smaller.
Sound this will help for my exam
Did you do well ??
Wooow Amazing🥰🥰🥰🥰👍👍👍👍👍👍

“What concentration of NaCl has an equal osmolarity to potato tuber tissue?”

Hi, what can be a negative control for this experiment?
Thank you
Hi. Can do you calculate to get the average change in length. I need the whole formula to understand please. Help me
Wildly variable results for the 3 cores in pure water ? So am I to understand that this is not a good way to get a nice salty taste in your potato ?
❤😂 thank you for your support
Which concentrations result in the movement of water into the cells?
"wo'oh" Lol.
