Independent Variable In Vinegar Egg

Over three days, we tested what would happen to an egg after leaving in various liquids over a 24-hour period. Before letting the egg submerge in vinegar overnight the initial weight of the egg was 66.6 grams. We thought that after leaving the egg in vinegar the shell of the egg would get softer. The independent variable is the vinegar and the dependent variable is the egg. We believed that the egg would be softer; because we saw the vinegar bubble once we put the egg in it. When we came back the second day we saw the egg looked like it enlarged, the shell looked like it was cracking, and felt bouncy. The egg weighed more than before, it weighed 80.23 grams. Our data supported the hypothesis because the shell wasn’t as hard as the day before. These days’ data was a hypotonic solution because there was no met movement of water, therefore the egg enlarged. On day two we recorded the data, then we poured the vinegar out of the cup and added distilled water in, to leave overnight. We predicted the egg would get softer, bigger and bouncier than before. Our independent variable was the distilled water and dependent variable was our egg. We thought the egg would get bigger through deductive reasoning because …show more content…
We came up with the hypothesis that the egg would expand or break. The independent variable for this would be the corn syrup and the egg will be the dependent variable. We believed the egg would expand, because looking at what the other liquids, the made the egg expand. When the fourth day came around we observed that the egg had a dent, it felt very soft and felt lighter than before. It now weighed 64.92 grams, just a few grams less than the initial weight. The data did not support our hypothesis because it did the opposite of expanding, it got smaller. This was a hypertonic solution because the syrup just went into the egg, which caused the egg to swell and
