In AP biology we talked about Osmosis and Diffusion. Osmosis and diffusion are the very simular. Osmosis is diffusion that happens in water. We tested two themes using bags and different solutions . We joted down the changes after each solution went through diffusion or osmosis. The lab we completed was dealing with a few different molars. Students used tubing to hold the Glucose/Starch solution. Then tubing was placed with the solutions. Over time the water changed color. This responce clearly showed that though the process of osmosis, the glucose/starch solution transported itself to the water solution that surrounded it.
