These sites are about molecular movement. Find out how diffusion and osmosis are different, what they are, and what factors affect molecular movement. Includes lesson plans, experiments, interactives, and quizzes.
Diffusion & Osmosis with Data Analysis
This simple in class experiment demonstrates the principles of diffusion and osmosis. NOTE: This site includes ads.
Diffusion, Osmosis, and Dialysis
This interactive lesson plan incorporates concepts of diffusion and osmosis into real world situations. Quiz questions, experiments,and questions about those experiments are included. NOTE: requires download of the JAVA app.
CoreChem: Osmotic Pressure
This entry in the "living textbook" CoreChem discusses osmosis and membranes.
Khan Academy: Diffusion and Osmosis
Short video lecture on diffusion and osmosis. Includes an explanation of solvents and solutes, membranes, and other related topics. NOTE: this site includes a comments section.
Watch a movie by Tim and Moby explaining diffusion, movement of molecules, and examples of diffusion and its application in real life. Includes an activity, a quiz, and an experiment. NOTE: A subscription is required for this site.
The Cell: PassiveTransport Diffusion
This interactive learning unit illustrates how molecules move in a passive transport diffusion process. NOTE: This site includes ads.
Osmosis and Diffusion Resources
This site compiles resources including lesson plans, experiments, slides, and interactives, on osmosis and diffusion. NOTE: There are few broken links to the resources.

Animation: How Osmosis Works
View an animation showing how osmosis works and then take a quiz.
Under What Conditions do Cells Gain or Lose Water?
Do an experiment in a virtual lab to examine how and why different types of cells gain or lose water in different solutions.
Lesson Plan: Diffusion, Osmosis and Cell Membranes
In this lesson plan, students learn about properties and processes of the cell membrane and conduct laboratory activity to understand the processes of diffusion and osmosis in cell membrane.
