1 Hypothesis
If you soak an egg in vinegar, then the shell will deteriorate and loose centimeters off of it's circumference.

Data and Observations
Time (hrs)
Observations
Circumference (cm)
0
1. The egg is whole, and has not lost color.
2. The egg was immediately surrounded by bubbles.
3. 14 cm
4. 24
1. The egg appears to have a little bit of color missing.
2. The egg remains firm.
3. 15.5cm
4. 48
1. The eggs shell is beginning to disappear.
2. The shell of the egg is cracking all around.
3. 16 and ¼cm
4. 72
1. The shell is completely gone, leaving a thin membrane that surrounds the yolk.
2. The egg itself looks flimsy and appears transparent.
3. 17cm
Conclusion:
Be sure to answer the following reflection questions in the conclusion of your lab report:
1. How much did the egg change in size? (answer should be in centimeter)
The egg's size changed by 3 centimeters.

2. Was your hypothesis correct? Why or why not?
My hypothesis proved to be correct because the egg's shell did, in fact, deteriorate.

3. Evaluate the lab and data collected. What type of transport occurred in this lab? Explain your answer, including evidence from your experiment to support your explanation.
The type of transport that took place in this lab was active. I believe this is true because the particles moved from an area of higher concentration (vinegar), to an area of lower concentration (the egg).
4. Consider how lettuce or spinach placed in water becomes firm and crisp. Use what you have learned about cell membranes to explain this observation.
Lettuce and spinach become firm and crisp when placed in water because the cells absorb the water, and in turn makes the lettuce/spinach bloated with water.

5. If you were to continue this experiment by removing the egg from the water and covering it in syrup, what do you think would happen. Explain your prediction. (If you choose to test your prediction, be sure to allow at least 24 hours before making your observations. And, of course, handle the egg very carefully!)
If I were to put the same egg in a syrup solution, I believe the thin membrane that remained would break because passive transport would take place.

When the experiment was finalized the vinegar solution enlarged the eggs mass. Before the vinegar solution it was 55.1 grams and after the solution it was 67.9 grams. The volume of the egg was also increased. At the beginning it was 50 mL after the solution it was 60 mL; it had a 10 mL difference. It is visible that a hypotonic solution was present. This rejects the hypothesis made. When the egg was placed in 150 mL of vinegar and left intact overnight the egg did sink to the bottom and remain that way, however, the mass was increased instead of keeping it the same, by approximately 13 grams. Furthermore, the volume was also increased it did not remain the same. By analyzing the data it can be determined that the water had a larger concentration and did not have to balance out with the vinegar. The vinegar acted in a peculiar way although it eroded the shell and took some weight off the water flowed inside the egg due to the low concentration of the vinegar.…

At the end of our experiment we saw that there were drastic changes to the eggs. The corn syrup egg lost nearly half of its water content making it shriveled and very fragile. The vinegar egg stayed the same and it did not lose or gain vinegar. With the salt water egg we had two of them lose water and one of them gain water. The largest egg of them all was the vinegar egg.…

As discussed in the intro, the purpose of this lab is to observe principles of homeostasis and osmosis in action. The results of this experiment showed that eggs placed in a 4 M sucrose solution lost mass over time and had the greatest percent difference in mass compared to the eggs in other solutions, with the 4 M egg having an average of -25.13% difference in mass. The 0.0 M solution egg only had a 12.28 average percent difference in mass, the 0.5 M egg with 10.39%, and the 1 M egg with the least percent difference in mass, 6.40%. The 0.0, 0.5, and 1 eggs all ended up gaining mass over time whereas the 4 M egg was the only one to drastically lose mass. This occurred because of the levels of concentration of solute in the different solutions. Since the 4 M solution had the highest concentration of solute, compared to the other three solutions tested, and a higher concentration of solute than that of the solution inside the egg, it was a hypertonic solution.…

In order to complete this experiment, one of the most important things you need to know how to do is how to take the outer “shell” layer off of the egg. The egg shells contain an element known as calcium carbonate. This element can be turned into carbon dioxide when combined with acetic acid. You can find acetic acid in vinegar. {Guenther, Leanne. “Soft Shelled Eggs.” Kidzone Science, Kidzone Science, 1998, www.kidzone.ws/science/egg.htm.}…
