Egg Lab Write Up The purpose of this lab was to depicked the many properties of diffusion such as isotonic‚ hypotnonic‚ and hypertonic‚ so that students could have a clear visual example to go by for future refrences. We also did this to learn about selective permeability and osmosis. Our original hypothesis stated that the vinegar would react with the calcium in the shell to create CO2 bubbles. Note I said the original hypothesis as this experiment took coarse over a four day period‚ in which
