Instructional Ideas

  • Have pupils write a summary of the process of osmosis following the demonstration
  • Begin the simulation at the beginning of class and check the compound levels during the last 15 minutes of class
Classroom Considerations

  • Requires laptops with Internet access if running the simulation independently
Pros

  • Allows users to manipulate different variables
  • The use of color provides a strong visual
Cons

  • None
