Description
- Activities will be performed utilizing dialysis tubing and various concentrations of salt Dyes of different molecular weights will also be used to visually demonstrate the size selectivity of membranes For 5 lab groups Students will learn the following concepts: Diffusion of small molecules across cell membranes is important for transferring nutrients to cells and removal of certain metabolic waste products Dialysis across a semi-permeable membrane can retain certain molecules and allow others to diffuse based on respective signs Water molecules move from low salt to high salt concentrations when separated by dialysis tubing Order Info Class size: five groups.
