Curated OER
Mystical Membrane
Students investigate osmosis, diffusion and a semi-permeable membrane. In this cell membrane lesson plan, students observe the movement of molecules out of a bag filled with sugar and starch into a beaker of water. They test the beaker...
Curated OER
Diffusion Across a Selectively Permeable Membrane
Students investigate how water passes through cell membranes. In this biology lesson, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.
