In order to give them a view of how diffusion works with a semipermeable membrane, i like to do a lab that uses a plastic bag to model the cell (membrane) it is a simple lab where students do very little except watch the process and record data and information.

Dialysis tubing is used to simulate a cell membrane it is permeable to small molecules and water, but not to larger molecules given the generally larger size of polysaccharides, it is hypothesized that starch will not pass through the dialysis tubing, and that iodine will pass through the membrane due to the small size of its molecules. In lab 1b, it can be concluded that sucrose cannot pass over a selectively permeable membrane, but instead water molecules will move across the membrane to the area of lower water potential to reach dynamic equilibrium. Water lab report - water is a charged or polar molecule (h+ - o- - h+) that is always moving across cell membranes scientists theorize that this is possible because it is such a small molecule or because there are special gap or pores that allow water movement through the cell membrane.
