Egg Osmosis (Hypertonic vs. Hypotonic Solution)
HTML-код
- Опубликовано: 24 фев 2012
- [I made a mistake in calculating percent change. Percent Change = (Final Mass - Orginal Mass) / Orignal Mass. Sorry!]
To test the semi-permeable qualities of the inner membrane of an egg shell, I place one egg in a hypertonic solution (corn syrup) and one egg in a hypotonic solution (water).
Using time-lapse footage, you can watch one egg shrink in size and one egg increase in size due to osmosis (the movement of water through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration) in order to reach dynamic equilibrium (a state in which all regions have an equal solute concentration).

Me in grade 9th rn watching this while reading biology and I just realized this video was posted 9 years ago wow 😭
Bro I am also in 9 class
Same here i was also reading biology and i am also in class 9th😂
Samee
Me too
Bro same i am also reading biology in class 9
Rip. Doggy
Until I found out it was milk😐
Me to bro me to
We share the same brain cells
Same here😅
@@adenikeomotosho2786 some thing l can't understand can you please explain to me
The world needs teachers like you. Great job :)
Thank you! :)
7 yrs Ago 😳
Sameee batch(2022)
My BMS lecture instructor this semester is all about application, and your demonstration is the absolute best example of hypotonic vs. hypertonic that I've seen. Thank you so much!!!
Btw, if water did move from a region of high solute concentration, then the solute concentration on that side would be even higher, thus not achieving dynamic equilibrium.
Sorry I didn't understand what you say . Can you please explain?
Yeah, there would be no change in amount..
@@khemrajnagar6097 can I ask you a question please??
Samajh nahi aaya par sunke accha laga
I was shouting at my phone while watching the dog drink. Glad it was fake! And thanks for this video. :)
You're welcome! It was funny to prank my students when they were watching the video, because they had the same reaction. :) But it was not so funny to prank strangers that posted hate comments before seeing it was a joke!
Same here
Great! You explain biology better than my teacher haha
Jhon Torres She did explain biology better than my teacher too ; haha
Imagine your teacher literally sees this comment dude.She would probably use this way of explaining
@Aiden Kim Same shi here!😅😂
𝚆𝚝𝚏
Ya that's true
you are now teaching our school for biology homework
(Henderson secondary school)
thank!!!
That's awesome! Thanks for letting me know!
We did this experiment in class. (I am a science teacher) You were very professional and to-the-point. Good job.
After 2 days
mass:
+water : decrease 43.3%
+corn syrup: increase 83.4%
formula:
((m2-m1)/m1)*100%
Great video, the descriptions are clear leaving no confusion at all, and I absolutely love the sound of your voice!
PS: I find it very annoying that people are not paying attention that you actually gave WATER AND MILK to your dog. Plus, no dog would drink such salty nasty water... people need to pay more attention
oop
@Niv Mizzet Did you understand the original comment? The person was pointing out others who thought it was real.
@Niv Mizzet do you know how to read my guy
Yes you're right
@@marshoul2717 you are right hmm...!!!
You saved my life! I am now prepared for my exam tomorrow thank you!
Yay! And good luck!
Thank you very much. I have a really bad biology teacher and this has helped me a zillion. I really like your videos. They are simple and fun 😊
Xolette I just want to thank you with all my heart. i had to preform this experiment for my Plant Science class by tomorrow (wed 09/15/21). and here I am Wednesday at 1:00am doing a multi-day experiment in 2hrs. God bless your soul.
I was having the HARDEST time with understanding Hypotonic vs Hypertonic and this video has helped me SO much!! THANK YOUUUU!!!
Excellent! Glad it helped you out. :)
I understood it very well. Clear and precise I thank you from the bottom of my heart.
Amazing video! U explained things so easily that anyone could understand. Nice work, we're waiting for more videos.
This video is great! I had really been struggling to understand this topic and am so thankful to have found this!
who’s here cuz of there teacher meh 😓🙋🏻♀️🌚
My teacher gave us exactly 5 days and since she hasn’t technically posted the assignment and I only got the video today I only have 4 days meaning if I mess up I would fail and it counts as 20% of the grade
Same thing with mine I wanted to start today then found out I have no eggs 💀
im here because i had to go to a funeral today
so i had to do the work on my own today
😁
YEONJUN
You helped me out with my Biology homework! Thanx! xD
You're very welcome!
+XoletteScience hi
SAME!!
Same
HappySolarSystem 5 Year wow
You really helped me with my biology experiment ! Also, very well explained !!
When she teaches better than my biology lecture teacher..RUclips Professor’s for the win
5:32 i laughed so hard there 😂
What a great instructional video. Thank you for describing what was happening in such fine detail. I really appreciate your effort! A+!!
Lmao the reason people freaked out is cause we don't care if you drank the saltwater but giving it to a dog is crossing the line 😂
Great experiment!
I'm definitely going to try it when I finish my finals.
Thank you, but it is correct. Osmosis is the movement of H2O through a semi-permeable memrbrane in which H2O will tend to move towards the higher solute conc. (if the conc are uneven) to reach dynamic equilibrium. Once that state is reached, the water will still move but equally in both directions. Active transport is the movement of PARTICLES (not water) from a low solute concentration to high solute concentration, but requires energy. Osmosis doesn't require energy.Thank you for the comment!
Omg, I learned this last year, but I can't remember this year so I watched your video and it came right back X333 I have an exam tomorrow and watched thjs and it is so helpful! Thank you so much~
Ooooiooo u so funny
im creeped out now xD ARMY is everywhere...
Thanks a million for this experiment. It truly opened my eyes to hypertonic vs hypotonic. Great video!!!
Thanks, Mellashon!
You're welcome
i was about to go off cuz i thought you gave the dog salt water. But you didnt. well played. well played
Great video and very well narrated! & I love your dogs 😊
I love it! Biology, chemistry and entertainment all in one.
this made the concept so much clearer. THANKS!
This is really amazing! Thank you so much for making this video! You're amazing! :)
Thank you for the ending, it was satisfying xD
Thanks for ruining my right ear while I was wearing earbuds.
Nonamus Gaming shouldn't have worn ear buds
Wow!!who says biology is boring if u hv such a grt teacher 🙏🙏
Love the video! Going to do this experiment tomorrow teaching high school students about the differences in IV solutions and what they do to cells.
oh man i was dying to know what happens when you pop the egg hahaa
Very useful video, really helped me understand osmosis.
That was the most helpful video I've ever seen, before this I could not comprehend osmosis to save my life. Thanks!
You're very welcome!
Thank you so much! You teach much better than my teacher, I can finally understand this topic now
If someone misunderstands this and gives their dog a glass of water with that much salt it would definitely die..
No animal would drink it.
It was just a joke, obviously you shouldn't give your pets salt water. Who knows if they would even drink it someone did give them salt water
Oh my god!!! You got me so good!! I freaked out when dog #2 started drinking the "salt water" Ahhhh!!! Hahahahaha!
You explain better than my biology teacher. And thank you for helping me to understand this.👍👍👍
10 years later this is absolutely amazing greta video!
Thank you!!
your adorable lol tx i watched this right before an exam helped refresh my memory tx:) 👍
best explanation ever, thanks!
I already knew all this because I'm a happy science nurd but I really liked the way that you showed Hypotonic and Hypertonic solutions with eggs great job!
Great example with the eggs! You can observe the same process with umibudo (sea grapes), no shells in the way!
I meant "inner isotonic solution"
Ok but how much do I pay someone to EAT those eggs? I need to know about flavor profiles. For science.
Ugh had to go through all of the new youtube updates just to comment but.... Thank you so much for this video, so great!
Thank you so much... You helped me understand clearly about hypertonic and hypotonic (earlier i was confused about these two terms). I have a question though - how did you calculate the change in mass? I really hope you reply... thanks..
I NEED HELP>.< sorry... does the increase of salt in water decrease/increase the weight of an egg?? please help asap...
i already tried the experiment however the numbers had no correlation, and according to the internet, the numbers are meant to decease... So im confused, please help, as a student
yosupbro1 If you tried the experiment, then you should be able to answer your own question. In the salt solution, did your egg increase in size (water entered the egg) or decrease in size (water left the egg)? When you watch this video, does the egg increase in size or decrease in size when placed in a hypertonic solution? That is all you need to know to answer your question.
oh, so it decreases mass as more salt is added, due to the decreasing amount of water right? Although the egg did decrease in size for the hypertonic solution, i am still slighty confused. Salt water has a high concentration and osmosis is moving from a high concentration to a low concentration, so shouldnt the mass increase?? Im so confused. And i ont have enough time to repeat my experiment...
yosupbro1 You are correct in your first statement and I see why you're confused. My students do the same in that they confuse the definitions of diffusion and osmosis. First of all, solutions want to reach dynamic equilibrium (DQ)-- this means that the concentration of the solution wants to be equal everywhere. Diffusion is the movement of PARTICLES from a high to a low concentration to reach DQ (imagine dye particles moving and spreading out throughout a glass of water). Osmosis is the movement of water through a membrane to reach DQ. Why does water move instead of the particles? It's because the particles can't move through the membrane as these particles are too big. Water molecules are smaller and can pass through, so to reach DQ, the water has to pass through this membrane. Therefore, the water moves from a LOW concentration of solutes to a HIGH concentration of solutes. Think of the egg releasing it's water so it can water down the salt solution in order to reach DQ. The opposite happens if the egg is placed in pure water. Water moves INTO the egg to water down it's inner solution to match the concentration of the outside solution. You can think of osmosis as water molecules, that want to party so they head towards the crowded particle party. For diffusion, think of anti-social particles that just want to be spaced out and move away from the crowd.
So overall, go over your definitions of diffusion and osmosis. It gets easy to mix up the two, especially when they use the same vocabulary. Good luck!
Thats a cool experiment
Thanks!
The world needs teacher like you madam
Thank you! You explained it so much better than my Biology Teacher :)
Sounds like something one of my students would do :)
nothing can be more clear than this explanation.
This video was awesome all the way to the end .Thanks!!
You just saved me from having a late assignment. Phew! Thanks
Thank you for this video!!
I have finally,clearly understood your experiment!👍
Yes, as long as the solution is hypertonic, meaning it has a A LOT of solute (like salt) then you're good to go. I've done this experiment before with water and sugar as my solution, and I feel that the corn syrup has a much more dramatic reaction in comparison (meaning the egg shrunk more and a lot faster).
You're an amazing teacher! Thanks a ton
We did this in science class, and this really helped with my lab report!!
So if I administer a hypertonic to a patient its going from high solutes to low solutes once it enters the body because the extracellular space is going to go into the cell to increase the intracellular fluid. Considering the patient is probably dehydrated(causes cells to shrink) RIGHT?? ...Im SO CONFUSED!!! LOL. #Life of a Nursing Student
You helped me understand hypertonic and hypotonic solutions thank you so much!
Thanks Xolette
I show this video in my Bio classes. Well done.
THANK YOU SO MUCH! I've actually learned something about this stuff!
I am going to be doing this tonight for my Bio Lab...Very interesting video, I never knew about this..Fingers crossed lab goes well tonight. Replay!
thanks! nice and clear explanation of hypertonic, hypotonic, and isotonic solutions
Really nice!! Awesome experiments!
Excellent! Before this lesson I tell my students about a family who was stranded at sea and how they drank turtle blood to remain hydrated. :)
Very nice experiment.... Actually I was confused with hypotonic and hypertonic solutions ... This VDO made me understand those solutions... Thank you
Thats a pretty good experiment!
I love your voice. It feels like your just talking right next to me.
You just helped me understanding things from physiology! Thank you
You're very welcome!
Quality, home made video. Excellent work!
My teacher showed us this instead of explaining in my online class lol
When the dog started drinking all my class, including the teacher, started to freak out. It was fun, thx for the video!
My students were yelling at me, some getting out of their chairs, when I showed them that part. It was a funny prank! :) Too bad since people miss the caption! Glad your class enjoyed it!
Egg: tries to create chick
Talking Monke: "your shell must melt*
Thank you so much for helping me with my bio homework!
I kept the eggs for three days in vinegar but there's no change 😟
Well explained!Thanks for sharing the knowledge :)!
The IV is the factor you're adding to the experiment. The DV is what changes as a result of the IV (The dependent variable DEPENDS on the independent variable). Constants are what remains the same in your experiment. The control group never receives the factor being tested and is there for comparison.
this is pretty cool haha :D i'll def remember this for my test tmrw. thanks!
Extremely helpful! Thank you
Gee, i already watched several vids about hypotonic and hypertonic but yours was the best! it made my brain cells alive again. THANKS for the very educating and entertaining video :) Wish me luck on my exam tom. Huhuhu :(
wow thank you so much...you madr the concept clearer love ya!! ..the water on the corn syrup wow-ed the hell out of me hahah
really decent detailing! keep it up!👌👌
Awesome video! Nice to see people using thier brains on youtube. Oh and that was HILARIOUS when the dog tried to eat the egg rotf
what a great video!!! i enjoyed very much! thank you !
Welcome! I did try this lab in class, but it was too time-consuming for my students (you have to wait a 1 - 3 days between each step). It makes a great demonstration though. :)
The only thing you missed was maintaining a standard- a regular egg to measure the difference against. Finding 3 eggs that weighed exactly the same could be a challenge tho- lol. I loved the stunt water- u got me!
If after soaking the egg in vinegar, you placed it in an empty beaker, would it decrease to it's original size(the same as a raw egg)?
thank you so much for the help!!
Thank you soooo much i wish you were my biology teacher you teach things very clearly
Thank you this definitely helped me out for my biology evaluation
That was a nice experiment! I have a question though. What will happen when the egg without the shell is placed in a soap solution?
