Understanding Osmosis

The three parts of this activity can be used as a coordinated sequence to develop student understanding of osmosis or you can use each part separately (provided your students have the needed background specified for each section below). "Introduction to Osmosis" presents a series of questions that guide students in understanding the basic process of osmosis and relevant vocabulary. "Demonstration of Osmosis Using Chicken Eggs" can be used as a classroom demonstration or a hands-on student activity, with questions to guide students in understanding the changes in volume and appearance of the eggs. "Challenge Questions" presents questions which challenge students to apply their understanding of osmosis to interpret phenomena observed in halophilic archaea, freshwater plants, and humans.

The Student Handout is provided in the first attached file and the Teacher Notes are provided in the second attached file.
