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 discover osmosis. Six activities in all, this collection is a must for your biology class! Lesson plans are thoroughly written and the activities are both engaging and informational. Thank the National Science Teachers Association for this gem of a resource!
