Osmosis and Diffusion Lab: Honey I Blew Up the Bear
Beginning biologists explore passive transport through two demonstrations and a hands-on inquiry. Spray air freshener from one spot in the classroom and have class members raise their hands as the scent reaches them. Also, place a teabag into a clear glass container of hot water for them to observe.
