Introduction: The purpose of this lab was to explore concentration gradient, diffusion, and osmosis further. Egg one’s circumference ( the long way and short way) and its mass will be compared to egg two’s circumference and its mass. In this lab we look at concentration gradient and osmosis. Concentration gradient is the difference in concentration from one place of high concentration to an area of low concentration. In an egg, there is protein, carbohydrates (sugars), and water. We are also studying osmosis. This is diffusion of water. Because of concentration gradient, osmosis can happen. When the shell of the egg has been removed and left just the egg’s insides and membrane left behind, both of these processes can take place. We have learned …show more content…
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
