Water Potential

In this video Paul Andersen defines water potential and explains how it can be calculated in a simple system. He explains how water can moved through osmosis and break down the two major parts of water potential (solute potential and pressure potential). He finishes the video with a sample calculation of solute potential.

if someone could give this man my teachers salary because he actually has taught me, that would be great

[Bozemanscience]

You should start by watching the video on the AP Biology test. I have organized all of my videos on my website under the AP Biology heading. Best of luck on the exam.

So who else here regrets deciding to take AP Bio

[samanthaverini]

I can't tell you how thankful I am for this video. I'm in my first week of AP Biology and was struggling with this concept until now. Our first exam is tomorrow and now I'm entering it with full confidence. Thank you so much for taking the time to reach out and demonstrate this concept for others!

[notesthyself]

Love how you break everything down and explain everything systematically. Thank you

[imfightingafrickinrock]

Hi, Mr. Andersen. Your videos are highly pedagogical, fun and easy to watch. Every time that I have a new subject in my Biology class, I look at one of your videos, and even if the topic is difficult, your videos are the best guide for understanding almost anything. You are a fantastic teacher!! Thankyou for making all of these videos :) // A Swedish student

i always do a small dance to the song in the beginning
