Innovating Science™ Small Group Learning: Diffusion And Osmosis
Students study the movement of water and nutrients across a cell membrane and observe osmosis in living tissue, investigate the relationship between surface area and volume as it relates to cells and diffusion and examine the concept of molarity as related to osmotic potential and water movement.
Supplier: Aldon Corporation IS3704SGL
