In this laboratory you do a number of exercises to demonstrate diffusion and osmosis.^* There are no new techniques for you to learn in these exercises, so we present just brief overviews here. If you don't want to review, proceed to Analysis of Results, where we focus on calculating water potential.

Exercise 1: Diffusion
Exercise 2: Osmosis
Exercise 3: Water Potential of Potato Cores
Exercise 4: Water Potential & Exercise 5: Plasmolysis
Analysis of Results

^* As described in the Advanced Placement Laboratory Manual.
