1 Learning Targets “I Can...” -Define “selective permeability.” -Model a living cell by using eggs with a dissolved shell. -Predict the results of an experiment that involves the movement of water through a membrane. -Recognize cells that are in a hypotonic, hypertonic, and isotonic solution.

2 Diffusion and Osmosis with Eggs

3 Background Some things can pass through the cell membrane and some things cannot; this is called selective permeability. As chemicals pass into and out of a cell, they move from areas of high concentration to areas of low concentration. This process is called diffusion. diffusion Water can also move into and out of the cell by osmosis.

4 Modifications to Procedures Goggles and aprons are NOT necessary Use cups instead of beakers Add enough vinegar to cover egg
