Product Details

A two-part experiment to solidify the concepts of osmosis, diffusion, and semi-permeable membranes. Students will conduct trials first with dialysis tubing (an artificial membrane), and then with plant tissue (a natural membrane). They will compare and contrast the two systems and become familiar with the terms hypotonic, isotonic, and hypertonic. Relate these concepts to water balance in living organisms and evolution.Materials supplied for 24 students working in pairs.
