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...

WET Science Lesson #5: Pass the Salt Please! (How Road Salt Affects Wetlands)
As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Diffusion across a Selectively Permeable Membrane
Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

Passing Gases: Effusion, Diffusion and the Velocity of a Gas
We know that gases move throughout and out of our bodies, but why? And how? Learn about gas movement by analyzing rates of effusion. Additionally, watch an interesting precipitate reaction using gases to apply effusion, diffusion, and...

New Review Diffusion: What Can Popcorn Teach Us About Diffusion?
Why do some smells, like popcorn, linger when others seem to vanish as quickly as they arrive? Learners think through that concept then complete an online simulation to determine if temperature and/or mass affect diffusion. Next, pupils...
