Introduction to Osmosis
This activity begins with a student investigation of the phenomenon of osmosis and then moves to analysis of the mechanism and implications of osmosis. In Part I, "What is happening to these eggs?" students observe and analyze the effects of osmosis on eggs. In Part II, "Understanding Osmosis", analysis and discussion questions introduce students to the molecular basis for osmosis and challenge students to apply their understanding of osmosis to several real-world phenomena.
