Research Paper On Eggshell

The egg shell completely disappears due to the vinegar reacting with the egg; bubbles form on the surface of the vinegar and on the egg because carbon dioxide was produced from

The primary purpose of the lab was to test and observe the effects of the process of osmosis on decalcified eggs. Before the process, the initial weights of the eggs were taken and noted. Two eggs were then immersed in a deionized water solution. The same was repeated to the other two solutions of 20% and 40% sucrose. The weights of the eggs were measured after 15 minutes to note the change in mass due to osmosis and again after 60 minutes to take the final measurement. Overall, while some human error might arise in the weighing process, care was taken in handling the eggs and during the weighing process. As such, it was found that the eggs behaved as predicted. It was found that the eggs placed in the hypertonic solution lost

The osmolarity of a solution is the concentration measured of a solute. To determine the concentration of a solution, one must first understand what osmosis is and how it works. Osmosis is the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane according to the Britannica Encyclopedia. The semipermeable membrane is one that blocks the passages of dissolved substances such as solutes. This process, in more recent times, provides a more accurate study of how water can diffuse across a cell membrane when water molecules have a high concentration to an area in which they have a low concentration. It was originally studied in 1877 by plant physiologist, Wilhelm, Pfeffer. (Britannica Encyclopedia 2015).

For this project, I made a capsule for an egg that is to be dropped from about twenty feet. This capsule that I made was not what I was thinking at first but when I started to build it, I saw that this capsule would hold better than the one that I was thinking which was a triangular capsule with the egg in the middle but I saw later one that the egg would break if it hit one of the flat sides. The capsule is a cube that is made out of the tongue depressors and I used most of the yarn for the big cage and I used the Elmer’s glue to glue the tongue depressors together. I used pieces of the paper clips to hold the popsicle sticks together with the tongue depressors and some

The purpose to this experiment was to study the effect of osmosis in de-shelled chicken eggs in different percentages of sucrose solutions. Osmosis is the process, in which, water moves across a differentially permeable membrane. The eggs were soaked in vinegar to remove the outside hard shell but still leave the egg in its membrane. By placing the six de-shelled in different sucrose solutions, we tested the rate of osmosis. The eggs were placed in the solutions for an hour and weighed in fifteen minute intervals. Then, each weight was recorded and graphed. The results showed that the egg in the water solution gained the most weigh and the only other egg that gained a little weight was the one in the 10% solution. All the other eggs in the different solutions lost weight, even the unknown solution. According to the results the egg that was in the distilled water solution gained weight because it is the hypertonic solution. All the other eggs lost weight because they were placed in hypotonic solutions with different concentrations of sucrose. The egg that was placed in the higher concentration of sucrose lost the most weight. So, the higher the concentration of sucrose, the more water the egg lost.

The purpose behind the egg drop project is for students to understand the concept of momentum, collision, impulse and force. To do this, they will create a protective carrier that will surround the egg. The egg will then be dropped from a certain height. The device that is created should weigh enough to increase the time of impact, therefore decreasing the force of impact on the egg so it doesn’t crack.

It is time to take measurements and collect data. Take a ruler and measure the height of both eggs. The take a bit of yarn (enough to wrap around the eggs) and wrap the yarn around both eggs separately to get their individual circumferences. Then place both eggs on the grams scale individually to get their weights. Observe their color and shape to get some qualitative data. Rinse the beakers and fill both with 125 ml of water each. Place one egg in a beaker and place the other egg in the other beaker. Record the density by subtracting the current reading of water in the cup by the original amount of water in the beaker. To begin the experiment, remove the egg shells from the eggs. Take one beaker and fill it with 100 ml of vinegar. Take

An egg has a semi-permeable membrane, thus processes like osmosis could occur. Osmosis is the movement of water molecules from an area of higher water concentration to an area of a lower water concentration. Osmosis is important, especially for living organisms, as they help distribute nutrients in the body. An egg’s mass would change when it is soaked in different substances. The goal of this experiment was to investigate how an egg changes through osmosis. This experiment was done to show how substances affect the mass of an egg. To start off, an egg’s mass was measured by putting the egg in a beaker then placing it on a mass scale. The beaker was then filled with vinegar and left alone for twenty-four hours. After a day, the egg was taken

Layers practically spent their youth to maturity confined in cages no bigger than their bodies. The cages are densely packed next and on top of one another. Laying hens are frequently starved to maximize their eggs production. The goal is to maximize production with amount of effort. The way I see it: It is like life in prison for those hens. They cannot move and even flap their wings. Living in overcrowded area, it is a natural tendency for the birds to peck at each other. To solve that problem, new born chicks will get part of their top beaks cut off without any painkillers. Many chicks experience pain and unable eat for days. When hens can no longer produce eggs, they are killed and sent elsewhere. Why would one kill those hens? Can we still use them for

Table 1.1 shows that the egg increased in size (in grams) from 86.2 grams to 96.3 grams.

In conclusion, the data that was collected helped tell us that the solutions greatly affected the cell of the egg because it caused the egg’s mass to increase than decrease. Also saw how the solutions played a role in the phospholipid bilayer and saw how it altered the shape of the egg. However, it does not support my hypothesis on the affect the egg would undergo onced placed in sugar and water but sugar was not used in this experiment, but water was used and it didn’t affect the shape of the egg, all it did was cause the egg to be in a isotonic state. According to Khan Academy (2017), states that a cell is isotonic “When the extracellular fluid has the same osmolarity as the cell, there will be no net movement in or out of the cell”. Which

When the 4 eggs were weighed it was found that out of the 4 solutions, 2 were hypotonic and 2 were hypertonic. The mass of 2 of the eggs increased and the other 2 decreased after 60 minutes in the various solutions. Out of the 4, the most hypotonic solution was the distilled water; and the most hypertonic solution was the solution with 2.0M glucose. The

The eggs will increase and decrease in mass when placed solutions with different amount of solutes. This

4.14. The accuracy of the data is dependent on the correct controls being in place, Ensuring temperate stays the same throughout all solutions, making sure that the solutions are correct that the weight and size of the eggs are the measured correctly and that when the eggs are removed they are removed at the same time. Some of the eggs were not completely submerged in the solution this may cause some errors in the experiment and may have caused varying results. The eggs were of different sizes this also will cause the results to vary, Gathering eggs of exact size and weight would have ensured the results were correct. The eggs may not have been dried enough also causing results to vary; this can be fixed by ensuring that the eggs are thoroughly dried. The eggs were taken out at a time around about 24 hours, having an exact time to remove the eggs would have eliminated errors.
