Discussion
In my hypothesis I stated that the egg submerged into red water would gain weight and the egg submerged into yogurt would expand in size. I proved my hypothesis correct. The egg that was submerged into red water gain weight by 7.1 grams! The egg that was submerged into yogurt did expand because it gained weight by 1.6 grams. This happened through osmosis. The particles moved from outside to inside the egg because there wasn’t as many water particles inside the eggs.
During our procedure we were sure to consider all variables. Our independent variable was the substance that the eggs were submerged into. We made sure that there was no other substance in the beakers that we were using by thoroughly cleaning the beakers before hand. Our dependent variable was the mass and size of the eggs. We measured the mass of the eggs before and after the experiment. The dependent variable was the variable that responded to the independent variable. Our controlled variables were the substance that the eggs were submerged into, and the duration of the experiment. We didn’t add or take out anything for the duration of the experiment. Also the eggs were kept in the beakers for the same amount of time.
In our experiment the eggs changed quite a bit. As seen in Graph 1 the volume of the substances changed a lot from before the experiment to after the experiment. The red water gained 50 mL, and the yogurt gained 70 mL. The yogurt gained more mL because the yogurt is more concentrated than the red water. As seen in Graph 2 the mass of the two eggs changed as well. Egg 1 submerged into red water gained 7.1 grams and egg 2 submerged into yogurt gained 1.6 grams. Egg 1 gained more weight because there was a lot more water particles outside the egg than inside and egg 2 was closer to equilibrium with the substance.
The experiment was very successful. I was able to find out the concepts of osmosis and diffusion using eggs submersed in a variety of substances. One thing that I would change within the experiment would be the duration. I think it would very interesting to find out what would happen to the eggs after 1 week instead of 24 hours. I don’t think there were any problems during the experiment. If I were to repeat the experiment I would also test what would happen to eggs in the substances with the eggshells still on.
