This is an inquiry lab. The students will prepare and conduct an experiment to force their potato to lose the greatest percentage of its mass using osmosis.
Support materials: Make an overhead or other way of collecting the class measurements as you start and then conclude the lab.
Safety issues or specialized background knowledge: Be careful with sharp objects. Students should already know about properties of water, osmosis and diffusion. If you have talked about hypertonic and hypotonic cells it can be helpful.
