Osmosis Lab

Experimenting with Tonicity

About: Inner_about

Students will get their hands into action by using saline filled dialysis tubing submerged in varying solutions to represent osmosis. We will discuss the movement of water in hypertonic, isotonic, and hypotonic solutions.


After we discuss the basics of osmosis, we will apply that knowledge to a common disease in the United States: diabetes. We will discuss how elevated glucose levels in the blood affect our body’s cells, and the complications that can arise if sugar levels are left unchecked. I always finish each of my labs with a quiz that indicates what each student has learned!
