This lab explores the process of osmosis. Students use chicken eggs (one large cell) to test various fluids and find out what happens to each cell (egg) when placed in four different solutions. This is an easy way to show students the process of diffusion and osmosis in a fun way. This lab is constructed for a remedial life science class and a middle school life science class. If doing this with biology, I would give them some directions and their procedure but they would do a full formal lab write-up.
