Osmosis & Diffusion Lab

Graphically demonstrate that a cell's membrane is selective in determining which substances it allows to pass in and out. Using a semi-permeable membrane model that simulates a living cell, your class will observe how this process of diffusion allows the cell to absorb vital nutrients and eliminate wastes. Additionally, students will investigate the process of osmosis and learn how this passive transport of water through the cell's membrane maintains equilibrium. As a result, they will also learn what factors affect osmosis and how to quantify the rate of this critical process.

Your students will:

  • Construct models of cells using dialysis tubing to simulate the semi-permeable nature of the plasma membrane
  • Observe the effects of osmosis on a model cell
  • Study the effects of diffusion through a semi-permeable membrane
  • Predict the characteristics of substances which allow them to pass through a semi-permeable membrane
Includes enough materials for a class size of 40 students. Recommended for students in grades 7 through 10. Manufactured by Neo/SCI.
