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.
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!
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.
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
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!
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).
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~
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.
Osmosis is also considered passive because water naturally wants to move in a way so that dynamic equilibriums is reached, so water moves from an area of low solute concentration to an area of high solute concentration. No energy is needed, therefore, it is considered passive. Active Transport is active, because it requires ATP for solutes to go in the opposite direction that it would naturally go in.
Active Transport is considered "active" because it requires energy for substances to move against the concentratation gradient (from an area of low solute concentration to an area of high solute concentration). Naturally, substances want to move from an area of high solute concentration to an area of low concentration in order to reach dynamic equilibrium, where all the concentrations of substances are equal; therefore, diffusion and facilitated diffusion is considered passive.
Yes, it's important, esp. when dehydrated to not drink salt water, since water will tend to leave the cells to balance out the exterior salty solution with its inner hypotonic solution. I think your confusion is if the salt enters the cell? The semi-permeable membrane allows for water to enter and leave the cell, whereas bigger molecules can't enter the cell unless its "permitted", meaning through channels in the cell
Active transport is moving against the concentration gradient, so it requires energy (as this is unnatural) Osmosis does not require energy because it's moving to equal out the concentration gradients (which is natural), so osmosis (as well as diffusion and facilitated diffusion) are passive.
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
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!
If you mean dissolve the outer shell, you must place the egg in vinegar to do that. When you dissolve the outer shell, placing the egg in the hypertonic solution will simply cause it to shrink and shrivel up due to a lose of water through the process of osmosis.
All hypertonic means is that it has a higher concentration of solutes (dissolved substance) compared to the concentration inside the cell. To make a hypertonic solution, all you would need to do is add a LOT of solutes to water (which can be sugar, salt, corn syrup...)
I believe so. I haven't tried it. Anything that is hypertonic will work, so yes, I believe that syrup will work. I've used water with a lot of sugar in it before and that worked, but it takes longer.
Think of it this way, the egg naturally wants to have the same solute concentration as the syrup, so it gets rid of water to be "syrupy". When an egg is placed in just pure water, it wants to be the same solute concentration as the water, so the egg gains water, to be more "watery". Hope that makes sense! Sometimes my students get it backwards at first as well, trying to apply what they know about diffusion to osmosis, which is very different. :)
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!
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. :)
You have the concept backwards. Osmosis is when water flows from an area of low solute concentration (think of the inside of a cell) to an area of high solute concentration (think salt water) until dynamic equilibrium is reached. (Dynamic equilibrium is when all areas have equal solute concentration.) So, water would flow out of the egg, into the salt water, to even out the concentration of solutes on the inside and outside; thus, the egg would weigh less when placed in corn syrup.
Naturally though, PARTICLES move from a higher to lower solute concentration (think particles of colored dye moving through water-- the particles naturally want to spread out). But osmosis doesn't deal with particles in general, but WATER MOLECULES specifically, in which the water molecules want to move from a lower to higher solute concentration THROUGH a semi-permeable membrane, like a cell membrane. Just wanted to make sure you have both definitions correct :)
Sure! Independent variable is the factor you are testing (like testing the affect of sleep, a drug, etc). I always think of the IV being the factor you test in the experimental group, but not in the control group. The dependent variable is what changes according to the IV (i.e. the dependent variable DEPENDS on the independent variable). For example, if you're testing how sleep affects memory, the IV is amount of sleep and the DV is their ability to remember.
If you read the caption and the annotation, you would see that the salt water was actually a little milk and water. Last time I checked, dogs can drink small amounts of milk. Please read next time.
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 :(
Also, I believe you're confused about Active Transport and Osmosis. Those are different types of transport. In active transport, diffusion, and facilitated diffusion only particles (or solutes) move. Osmosis is when only the water moves.
Correction: Selectively permeable instead of semi-permeable. The latter means that 50% of each substance that wants to pass through can pass through, whereas the former is more accurate by stating that it only allows certain substances to pass through. (01:48)
+Bob Bolt This video was made for my tenth grade biology students. The definition of semi-permeable in this video is what is used when teaching biology.
+Bob Bolt I would recheck your definition of selectively permeable vs semi-permeable as well. (Selectively permeable allows particular substances to enter, semi-permeable allows solvents like water to pass through). I'm not sure where you got the "50% of each substance" as how much of the solvent that passes through the membrane depends on the solute concentration inside and outside of the cell.
The dependent variable is what changes as a result of the independent variable. Why do you expect to change (that's the DV); what is causing it to change? (that's the IV)
Thanks for this video so much. It has helped me with my homework! I pressed the like button cus i thought this video was very well crafted, made and edited. I could see and appreciate ur efforts! Keep these videos going
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!
Sorry, sent you the wrong comment. Osmosis is not an adjective that describes a solution. It's a process. Vinegar is mostly water and bit of acetic acid. So what do you think vinegar is, hypertonic or hypotonic? Watch the video again if you're not sure. :)

Very useful video, really helped me understand osmosis.
You explain better than my biology teacher. And thank you for helping me to understand this.👍👍👍
oh man i was dying to know what happens when you pop the egg hahaa
If you mean dissolve the outer shell, you must place the egg in vinegar to do that. When you dissolve the outer shell, placing the egg in the hypertonic solution will simply cause it to shrink and shrivel up due to a lose of water through the process of osmosis.
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
All hypertonic means is that it has a higher concentration of solutes (dissolved substance) compared to the concentration inside the cell. To make a hypertonic solution, all you would need to do is add a LOT of solutes to water (which can be sugar, salt, corn syrup...)
5:32 i laughed so hard there 😂

Ok but how much do I pay someone to EAT those eggs? I need to know about flavor profiles. For science.
I believe so. I haven't tried it. Anything that is hypertonic will work, so yes, I believe that syrup will work. I've used water with a lot of sugar in it before and that worked, but it takes longer.
Oh my god!!! You got me so good!! I freaked out when dog #2 started drinking the "salt water" Ahhhh!!! Hahahahaha!

I am sure it'll work since it's still vinegar. You'll know it's working if bubbles appear on the egg shell's surface (this is carbon dioxide).
Thats a cool experiment

Correction: Selectively permeable instead of semi-permeable. The latter means that 50% of each substance that wants to pass through can pass through, whereas the former is more accurate by stating that it only allows certain substances to pass through. (01:48)
+Bob Bolt You're correct, but for the grade level at which this is aimed, semi-permeable is an acceptable synonym.
Exactly what grade level are you referring to?
+Bob Bolt This video was made for my tenth grade biology students. The definition of semi-permeable in this video is what is used when teaching biology.
Over here in Singapore, we learn waaaaay earlier. I'm just 13. Confusion indeed.

(Selectively permeable allows particular substances to enter, semi-permeable allows solvents like water to pass through). I'm not sure where you got the "50% of each substance" as how much of the solvent that passes through the membrane depends on the solute concentration inside and outside of the cell.
