Students are experimenting on an egg first stripping away the hard calcium carbonate shell to reveal the soft semi-permeable membrane beneath.
From here...students submerge the egg into a variety of solutions to see how it affects the egg's shape, mass, and size. Questions for students to consider : 1) When you placed the egg in the acetic acid, did a reaction occur? How do you know? What signs gave you clues to this? 2) How did the mass change after each solution and why? 3) Explain this change in mass in terms of Osmosis. Comments are closed.
