This Cell Diffusion and Permeability: The See-Thru Egg Lab lesson plan also includes:
Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor measurements of the egg before and after being exposed to the liquids. A comparison of the measurements allows individuals to make conclusions about the permeability of the membrane.
