This lab project was to demonstrate the system of how osmosis and diffusion works. More specifically to examine the movement of how substances flow in and out of the cell membrane. Which was demonstrated by soaking an egg in various liquids with a time table to see how it would affect the egg. The egg can be substituted as the cell membrane. Predictions, observations, and procedures were made. Before the lab procedures can be discussed, Osmosis and other key terms should be mentioned and explained. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable (The Egg) membrane from a less concentrated solution, like water into a more concentrated one like corn syrup, making the concentrations on each side of the membrane equal.Similar to Osmosis diffusion is movement of particles from an area in which they are in higher concentration to regions of lower concentration. They do this by passive transport, which is the movement of those molecules without the requirement of energy. This will be explained further during the procedures and results.
For the experiment the instructions were laid out clearly, Materials were needed a glass jar, beaker, graduated cylinder, and paper bag. Other materials included were vinegar, water, and light corn syrup. To begin the procedure 400 ml of …show more content…
The predicted outcome was that the color will change and the egg will become harder. The egg was observed the next day and the syrup was gently poured out, the egg was touched and the observations were noted that the egg will become shiny and shriveled up. The same thing that happened with the vinegar also happened with the corn syrup. This was also due to diffusion and also osmosis. The corn syrup like vinegar actively transported from the high concentration of the corn syrup to the low concentration of the egg. Which did match our prediction as we said the egg will change its color and

Egg Osmosis Lab Report

The purpose of this experiment is to see how the functions of an egg relate to an animal cell and also see the effects of the different solutions that are used on the egg during the experiment. Also made a hypothesis on what will happen to cell when it is placed in water by saying it is going to cause the cell to experience osmosis and the altering of the shape of its cell membrane. This was proven wrong because the egg did not alter in shape, all it did was stay the same shape but increase in mass…

Egg Lab

Egg Lab Report The egg lab taught about diffusion, osmosis, and the different types of solutions, hypertonic, hypotonic, and isotonic. In our lab, we used an egg, a cup, a string, a rubber band, a ruler, a graduated cylinder (100 ml), saran wrap, vinegar, a soap solution, a salt solution, and a corn syrup solution. We measured our egg by wrapping the string around it. Our egg was 13.5 cm. During testing, we found our hypotheses were not always right. Day one of testing, we used vinegar. We thought…
