This just saved my life bless

The units under percent change in the table are wrong. They're supposed to be % not g.

you're amazing :) thank you so much

thank you, friend. the instructions for my online ap bio class are so confusing

i have a question! Please help me.. how can you measure the sugar concentration like how can you tell if it's .2M or .8M .. i need help T^T

My bio teacher gives us lots of video sheets for these videos, to make sure students actually watch the video. In my opinion (and probably my teacher's opinion, too), you'd be a fool to skip out on these videos. Bozeman science is able to help you understand what your teacher can't get you to understand. Even if you do understand the subject, watching these videos is still a great way to retain that knowledge. I'm glad my bio teacher is tech savvy and shows us these vids!

Its really helpful video .

really helpful ! :)

How come glucose what found in the beaker? Was its molecules small enough to penetrate the membrane?

Looooove your videos. Very helpful. Thank you!

dude!!!!! this is so helpful!!!!! My Biology teacher Mrs. O'Dear loves your teaching! she can't stress enough for us students to use you videos to help us. and it helps me. So thank you so so so so so much! You should go see you Biology teacher though. she loves your videos and she wants to like watch you do your stuff in person. she just loves you Mr. Anderson

These lab videos are such a blessing! Thank you soo much :)

Amen to my a1

What do you mean by the molarity of potatoes? Do you mean sugar concentration in the potatoes?

With the potato in 1.0M of sugar, why does it lose water? Does sugar suck it out some how? Why does water not fill it in?

You said from hypotonic to hypertonic, but isn't the high  concentration of water to low (inside the potato) hyper to hypo?

I used to find biology boring but now thanks to you I understand it and it's now interesting to me
Thank-you Mr.Anderson!!!!!

For this lab in my AP class, we have to do an investigative inquiry and change ONE variable in either experiment. Any suggestions? Me and my partner thought we might try switching the water to milk in the POTATO LAB but would that work considering you're measuring water potential? 

Thank you so much for clarifying it I have a test tomorrow and this helped me understand it

thanks for sharing, found that easier to understand compared to the way that i was taught as found that it was explained better 

Thank you so much! You're videos help me so much.

very very helpful!!

Thank you for sharing, for those of us re teaching this topic to our children, this was clear concise and to the point.  I appreciate all the effort that went into making this video.

Best explanation, Hands down. 

I wish I had you as a teacher while I was in school!
