This lab will be an experimentation with a raw egg going through osmosis. Osmosis is a solution moving from areas of high concentration to low concentration. (Glicksman, H. (2015, March 6) There are two different ways that this occurs, hypertonics and hypotonics. A hypertonic state is when the solution moves outside of the cell, because it is of a lower concentration. Hypotonics has the same concept except the solution is moving inside the cell. There is also one more thing that the egg can go through this is called the isotonic state. Isotonics is when the cell and the outside are equal in osmotic pressure. This means that the cell is equal to the outside of it. Nothing will happen to the cell until either the inside or outside become lower …show more content…

A plastic cup was used to hold the egg with the solutions, which were water and corn syrup. Paper towels are needed to be able wipe the egg off thoroughly. A scale is needed to be able to gather data about the eggs weight and to be able to weigh the egg properly a weigh boat will be needed. During this lab there were no difficulties that were experienced. But as always there are things that could occur, the membrane of the egg could bust, which means there would be no way to gather the data needed. So be very careful when moving the egg around. On day one, the egg will be removed from the vinegar. While picking the egg up be careful no to pop the egg. After the egg has been safely retrieved very gently pat it dry with a paper towel. After doing this, the egg needs to be rinsed. Go to the sink and get a slow stream of water flowing and take the pad of the thumb and gently rub the egg until the yolk is visible. The spot only needs to be about the size of a quarter. Doing this will allow what is happening to be seen. Now, gently pat the egg dry with some more paper towels. After the egg is dry, go to the scale and turn it on. Then put the weigh boat on the scale. Then press the button that says zero and wait until a 0 comes on. Carefully pick up the egg and place it in the weigh boat. Now record the weight of the egg. Place the egg back
