Egg Shells : Ain 't Nobody Here But Us Chickens !

The purpose of our experiment is to test animal behavior and reactions to a change in environment. Our guiding question is, “Why do living organisms respond to environmental factors?” This is basically a question that is asking why living things will react a certain way to environmental changes. The task to answer this question is to experiment with changing environmental factors with pill bugs.

Why do eggs only float in salt water and not freshwater? Eggs don’t float in freshwater because it is less dense that saltwater. In order to make an object that is more dense to float in an object that is less dense than it, you need to add a material such as salt in to the solution. When the salt water is makeing the egg float there is a process that is going on in the cup to

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 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 goal of this experiment was to find out how an shell-less egg’s mass and volume changed when it was placed first in corn syrup (hypertonic) and then in water (hypotonic) and why. The hypothesis was that when the egg was placed in corn syrup, it would lose mass and shrink, but when it was placed back in water, it would gain mass and swell up. The independent variable was the different tonicity of solutions that the egg was placed in; the dependent variable was the mass and volume of the egg. A pickled egg without shell was rinsed, weighed, and its dimension was measured. Then, it was placed in a cup and soaked in corn syrup.

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

The most extensive metamorphic changes of insects internal organs occur with development of the thoracic musculature required for flight, the arrangement of nervous system and the development of gonads [2].

Conclusion: My hypothesis was incorrect because I had initially thought that the egg would shrink because of the pH of the vinegar, however the eggshell got larger rather than shrinking. This is because the homeostasis of the cell was disrupted, which in result interrupted the function of  the phospholipids. Enzymes, which whom are catalysts for chemical reactions in living things, can only occur under tightly controlled conditions such as a small range of temperature and/or pH. A disruption would cause the hydrogen bonds to break and that would not allow the cell to properly function. Since the enzymes were not able to function correctly under the desired conditions, it would cause the egg shell to dissolve. In addition, because the shell

After the shell is finally gone, the egg will be placed in the salt-water solution. Since only water can move in and out of the egg, the semipermeable membrane allows for an “exploration for the concepts of diffusion and osmosis” (Ryczkowski 2014). If the solution is hypotonic, the egg’s mass (quantitative data) will increase because the water will pass from an area with high concentration (water), to an area with low concentration (egg). It is predicted that the egg will gain mass and look larger (qualitative data) because of

them clean. Because, an egg is tiny and is about 1 millimeter long it needs

I am doing the project ¨ Is an egg denser in saltwater or tap water?¨ While doing this project, I found a lot of things out. Objects such as eggs sink in liquids when their denser is greater than the liquid their in. It helps keep less denser materials floating. Density means the degree of compactness of a substance. I will be using EB eggs in my project. EB eggs are also known as England's Best. Since we will be using eggs in my experiment, that´s what’s we are going to be talking about. The outer layer of a egg is called a shell. Eggs have lots of protein, vitamins, minerals, good fats, and a lot of trace nutrients. Shells have about 7,000 tiny pores in them. Eggs shells are mostly made up of calcium carbonate. There is also an inner membrane, and an

Once the eggs are here the eggs go down the runway, like what was talked about in the previous paragraph. While going down the runway the eggs go through a sanitize wash to make sure they are thoroughly clean from any bacteria on them. At that point the eggs go through a high speed camera and UV lights looking for any imperfections in the eggs. There really is no human interaction before, during, and after the processes because there can be mistakes, especially from human error. What the Creighton Brothers do is they have a system looking for any imperfections in the eggs. If there is an imperfection, the machines will take the egg out of the normal, healthy eggs. At times though when they will have somebody look at the eggs through a light to see how everything is going, but according to our tour guides that is usually the USDA during the checkups. The eggs are then stored away in a refrigerated container, the temperature would be less than ten degrees, until it is time to package them and send them off to the location they need to go to. Those are what happens to the hard shell eggs, when it comes to the liquid eggs things are a little different. Eggs go through all of the process mentioned before, but the eggs will be cracked to get the yolk. The eggs can stay whole, separate the yolk, or they can boil the eggs. As soon as it comes to the actual liquid eggs, they are always separated. This

What type of structure does Insectopia have and what are the positive/negative effects of such a structure?

The second attribute that makes them so successful is that most arthropods have a small body size. Having a small body size can be somewhat disadvantages since you have to worry about being stepped on constantly by bigger organisms, but the pros outway the
