Product Details

Students will love this functioning diffusion model. The semipermeable membrane in the center of the model allows the passage of “small” molecules while keep the “large” molecules trapped on one side of the membrance. Randomly shake the model and watch what happens! The dramatic increase in volume on one side will help students visualize difficult concepts of diffusion and membrane permeability. A real must when teaching diffusion!
