Hypothesis
A) If diffusion and osmosis across a selectively permeable membrane are related to the substance the membrane is submerged in, then an egg submersed in red water will expand as a result of the diffusion of water (osmosis) inside the egg.
B) If diffusion and osmosis across a selectively permeable membrane are related to the substance the membrane is submerged in, then an egg submersed in strawberry yogurt will expand as a result of the diffusion of water (osmosis) inside the egg.
My Independent variable was the substance (red water and yogurt) My Dependent variable was the effect that the substance had on the egg. My Controlled variables were the substance and the duration of the experiment.
