Description:
Visualising Osmosis and Diffusion Investigation
Specification:
Vividly demonstrate selective permeability using coloured solutions. The
class will also learn how osmosis and diffusion permit the maintenance
of equilibrium through the passive transport of water through the cell's
semipermeable membrane. Starting with a model cell and a mixture of
special dye solutions, your students will observe how the cell's
membrane allows one dye to pass, while the other remains within the
cell. The resulting colour change provides a vivid demonstration of
selective permeability and how the cell absorbs nutrients and discharges
wastes. Class size - 40 students
