Exploring Diffusion 1.0

Take charge of your learning! Explore diffusion in a highly interactive environment.

To learn about the process of diffusion, carry out a few experiments in which you’ll place dialysis tubing filled with a solution into a beaker containing another solution. Then observe how molecules pass through the selectively permeable membrane.

• Learn about the selective permeability of cell membranes.
• Experiment with the motion of molecules by diffusion.
• Explore the effect of size on the diffusion of molecules through membranes.
• Learn the difference between passive and facilitated diffusion.
• Identify examples where diffusion has occurred.

App features:
• Investigate the process of diffusion by conducting interactive experiments.
• Make hypotheses and then analyze your data to draw conclusions.
• Receive hints and tips as you perform investigations.
• Demonstrate what you learn by taking quizzes.
