Do you want to see an example of osmosis that you can recreate in your kitchen? How about an example of osmosis occurring in plants? Want to see the egg example again? An osmosis animation? Explain why the large molecules in the osmosis animation remain on the right side of the membrane. Please share your thoughts!
So osmosis can happen in non-living and non-living things?

i thought non living things didnt have cells
ReplyDeletewhat happened to the outer shell
ReplyDeletewhat would have happened if we left the egg in the vinegar for 2 days instead of 1?????

If you continue on youtube, you can find better videos. Here's a good link:

Anyways, I was wondering: does the size or complexity of the molecules count? because if glucose was smaller, but still as complex, would it fit through, or can the protein channels sense its complexity and reject it? if another person, or leslie, could answer this, that would be great! enjoy your weekend!
The large molecules stay on the right because they are too big to fit through the membrane

i agree with bj. the big molecules are to large to fit thru the small pores.
ReplyDeleteWill this or something else on this blog be extra credit on our next quiz?
ReplyDeleteI wonder what will happen to egg tommorow.
ReplyDeleteIt's probably going to expand.
i agree with bj and Radhika too. My sister already did this experiment though so i know that the egg shell will become soft after 24 hrs
ReplyDeleteOhhh thats a nasty looking egg in the picture. Why does it turn brown? And can we crack it even thought it's all softy?
ReplyDelete~pia
koh
so osmois can happen in anything...?
ReplyDeletein the video osmosis went quickly
ReplyDeletein real lifer does it go that fast or was the video sped up? i cant really imagine nature going this quickly but...oh well, still would love to know.
You know, this is very general, but I seriously hate all of this science stuff. No, not meaning anything bad to to the study or subject (it's actually quite gross and interesting in Living Enviroment) but why did all this complication have to happen? Why couldn't God just make us all hollow, leaving many complications alone?
ReplyDeleteosmosis is such a weird thing of nature. it gets me concious of what's happening inside of me right now.... just like with the digestive system idea.
ReplyDeleteThe cooking in the kitchen video is hard to believe.
ReplyDeleteHey! It's Vera! I think the large molecules are too big to fit through the membrane, so that's why they stay on the right side of it.
ReplyDeleteanimation video was confusing at furst i didnt get it. then i realized what was happening and it was actually a very helpful video
ReplyDeletethats so cool! we did that during class! i have one question though. when the egg was put in corn syrup, why did it get smaller? the vinegar and the corn syrup would mix but the same amount should have stayed inside
ReplyDeleteThe kitchen video of osmosis may be true because I have this plant at home that looks dead but can easily be refreshed in a few hours by pouring a lot of water into it.
ReplyDeleteI must say, I never thought of an egg as a cell... I wonder why it is. I once heard that an ostrich egg is the largest cell.
ReplyDeletei agree with Emily L... I can't believe that there are so many things happening inside of my body and i don't even notice this.
ReplyDeleteOn quizzes, if you want to make sure people are reading your blog, then you can put questions about the blog to test them. I know you already do this fore extra credit, but if you put one on the quiz as a real question then people will really have to read your blog!

When water goes into a sponge, would that be a type of osmosis? Or is it only for living things?
ReplyDeleteThis is COOL!!

the egg looks really disgusting in the video. i showed my mom, and she didnt want me to do any experiment like that at home :( I think this is a great experiment
ReplyDeleteWait, so molecules small enough don't have to pass through the protein channels and can just cross the membrane?
ReplyDeletey didnt the shell break? isnt it hard and supposed to break?
ReplyDeletethat was cool! i didn't realize that when you put lettuce in water to freshen up, it's actually osmosis that's doing it
ReplyDeleteTHis is ausume the music is good and the salad thing is cool
ReplyDelete-alec
when the egg became deflated it looked like a hard boiled egg. im surprised the shell didnt break. why do you thing the egg shell turned yellow?
ReplyDelete- sophia m 7f
I thought it was pretty cool when they showed the lettuce grow in fast motion
ReplyDeletewow it's like you can see it growing in front of your eyes, it's amazing. the way it grows.

Looks like I got the Extra Credit wrong. I said onion. I should have known it was egg because we did it in class.
ReplyDeletehey leslie i thought this was really intresting and i loved how it like bloomed!! like a flower do you know if it was stop motion animation or it really was the pure blooming of this peice of lettuce??
ReplyDeleteis that where you got the idea for that egg experiment we did in class leslie?
