    Egg-Sperimenting with

    Shannon and Avery

    Initial Observations:
    I have observed that when put in vinegar overnight, egg shells will dissolve and leave the membrane holding the egg inside. I want to investigate whether the type of egg will change the amount of vinegar the membrane holds. Does the type of egg change the amount of vinegar the egg holds?

    Background Research
    So far, the only difference between a white egg, green egg, and a brown egg is the color. It isnt thicker, or made of a different material, but is laid by different kinds of chickens. Eggs are made of calcium carbonate, which dissolves easily in vinegar.

    Purpose
    Does the color of an egg have an impact on how much vinegar it holds after the shell dissolves?

    Hypothesis
    I think the amount of vinegar that the eggs soak up will be just the same because they are not made of different materials, only different colors. I think the eggs will soak up approximately 50 mL of vinegar each. My experiment will measure the amount of vinegar the eggs will soak up.

    Variables
    Independent Variables: White, Brown, and Green Eggs Dependent Variables: Volume of the Egg Vinegar Absorption Controlled Variables: Number of Eggs Amount of Vinegar

    Procedure
    1. Measure out 100 mL of vinegar and put it in 9 different cups. Label the cups with either W1, W2, W3, B1, B2, B3, G1, G2, or G3. 2. Get three eggs of each variety and put them each in a separate jar of vinegar, accordingly. 3. Take pictures at every two hours to see the shell deterioration and label with sharpie. 4. At the end of three days, measure the mass of the eggs using displacement. 5. Clean up and make the Craymondactyl happy.

    Materials
    3 white eggs 3 brown eggs 3 green eggs 9 cups vinegar (100 mL in each cup) paper towels 100 mL graduated cylinder with 1 mL accuracy camera

    Experimental Observations
    Type of Egg White Egg Brown Egg Green Egg Amount of Vinegar left in Cup 90 mL 71 mL 70 mL

    Analysis
    At the end of the week, the eggs measured differently. The white egg absorbed 10 mL of vinegar. The brown egg soaked up 29 mL of vinegar. The green egg soaked up 30 mL of vinegar.

    Conclusion
    The colored eggs absorbed approximately the same amount of water, but the white egg didnt! I thought all of them would have been the same, but they were not. Next time, I will add more eggs of the previous three kinds to get a better measurement for the mass. By adding these eggs, I will have more accurate data to measure because I can find the average mL they soaked up. We might have just had a strange outlier that was the white egg, so by adding more eggs to the experiment, we can know for sure if what we have is an outlier or just a normal white egg.
