Living things must perform vital activities in order to maintain their existence, including moving water in and out of cells. It is important for your students to understand how water flows in and out of a cell through the membrane that surrounds cells, as it directly impact a cell’s ability to survive. The passive transport of water across a selectively permeable membrane is called osmosis.
Your students can explore osmosis by using the Water Kits© to make models of the hypertonic, hypotonic and isotonic states of osmosis and predicting the flow of water in each state. They also will recognize the necessity of aquaporins in water transport across a membrane.
