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...

Cell Size and Shape; Diffusion and Osmosis Processes
Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

In Da Club - Membranes and Transport
Wouldn't it be great to learn about cells through osmosis? Introduce learners to the different mechanisms of active and passive transport with a video that shows how the different transports occur across the cell membrane, allowing only...

Transport Across Cell Membranes
Materials don't need a password to move through cell membranes! Learners explore how cells move materials across the cell membrane. The video then teaches the detailed workings of both passive transport (specifically diffusion,...
