Mystical Membrane

Learners 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 for the presence of starch and sugar and observe the movement of sugar molecules through the semi-permeable membrane while the starch stays in the bag as indicated by the Lugol's solution.
