Osmosis and Diffusion Kit 8 Stations
In this practical, dialysis tubing is used as a surrogate cell membrane for a visual demonstration of osmosis and diffusion.
This inexpensive and simple experiment provides students with a clear visual result that effectively demonstrates how the size of a molecule can affect its ability to be transported into or out of a cell. It also illustrates the mechanics of diffusion and osmosis by which a cell will attempt to create homeostasis, or equilibrium between its inner and outer environments.
