Students will study the movement of water and nutrients across a cell membrane and observe osmosis in living tissue. They will then investigate the relationship between surface area and volume as it relates to cells and diffusion. They will also examine the concept of molarity and how it relates to osmotic potential and the movement of water. Students will also be able to explain how cell size and shape affect the overall rate of nutrient intake and water elimination. Students will also use plant tissue to determine the molarities of unknown solutions based on the direction and degree of water movement. This kit contains enough materials for 8 groups. Teacher’s manual and Student Study Guide copymasters are included. Meets AP® Science Practices 2, 4, and 5, and Big Idea 2.
