This experiment took about 4 days to gather all the right measurement because both eggs had to soak in vinegar for 2 days. It is possible that a person ends up with 3 days of measurements because the eggs aren't observed each day. Conclusion: In the end, it was found that the Hypothesis at the beginning of the experiment was right. Egg one did shrink just a little bit. There was not enough information to observe weather egg two would have shrunk or not, however. Because egg one shrunk, as shown by the data above, it has been proven that the solution inside the egg was hypotonic and the solution the egg soaked in was hypertonic. One area of error for this experiment is the soaking of vinegar. As the egg soaked in vinegar, it starts to float. Since it floats, the parts of the shell that stay outside of the vinagre remain hard. This is bad when a person then tries to rub off the shell. The hard pieces of shell, if pulled off, can rupture the membrane. I would suggest finding a way to hold the egg down to the cup as it soaks so the entire egg is submerged. For this experiment, my information came from Mr. Devien and the Holton McDougal Biology
