Meets AP Science Practices 2, 4, and 5, and Big Idea 2.
- Three separate activities to quantitatively measure osmosis and diffusion
- Save time with well-prepared materials
Using two different models, students will simulate the movement of water and nutrients across a cell membrane and observe osmosis in living tissue, enabling a clear understanding of the properties of osmosis and diffusion and their role in maintaining homeostasis in the cell. As a result, students will be able to pose their own scientific questions about the selective permeability properties of cell membranes and provide explanation for how cell size and shape affect rates of diffusion. A refill kit is available and contains only consumable component items it does not contain additional student or teacher guides. Note: Due to regulatory issues, Elodea is not included in the new kit.
