Aldon Innovating Science Osmosis and Diffusion Lab Activity

Learn about two forms of passive transport by comparing and contrasting similarities and differences in the processes of diffusion and osmosis. Use a colorimetric test to demonstrate the movement of a solute across a semi-permeable membrane. Set up an environment likely to facilitate osmosis and gather data to determine whether or not osmosis may have occurred.
