This Water Potential instructional video also includes:
Water flow isn't solely based on gravity. Pupils explore the formula for the potential of water through a measurement of psi based on the solute potential and the pressure potential. The lesson analyzes the example of placing salt on a slug and explains how the solute potential is calculated.

Instructional Ideas
- Have a cheat sheet on which learners can take notes
- Pause video throughout to allow learners to discuss and process the formula and concepts
Classroom Considerations
- Lesson requires a computer, Internet access, and a projection system
- May want to show the osmosis video first, since osmosis is mentioned throughout
- Part 36 in a series of 37
Pros
- Includes a review sheet
- Walks learners through the formula, and a sample calculation of solute potential occurs near the end
- References the AP exam and gives examples of questions that may occur on the test
Cons
- Includes the formula for the solute potential, which may be overwhelming for some learners
