Egg Science Project

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 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.

Our body makes up around 70% of water. Needless to say, water has a lot of benefits for our body. A healthy person can drink three gallons of water per day. From our hearts to our kidneys, water all has something to do to the contribution to our body. It helps to refresh our body, push all the toxins out of our body and slow down the dehydration process or maybe, just to cushion our body joints. Wherever water travels, they carry nutrition, minerals with it into our body.

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

In society reproduction is one of the most important things that keeps our world's population growing. In these three short dystopian stories there are different approaches on ideas on what reproduction should be like and how it should be approached. Reproduction rights have an immensely big impact on each of these stories in different circumstances but are very much alike. These three different stories have different rules for the way they run their reproduction systems in their communities. Ten with a Flag the way the society has to do with reproduction is by a ranking system. In this case the people in the story find out how great their child is by ranking, so if the child is a ten it's perfect and if the baby has a perfect ten with a flag, the flag means that the baby might have something troubled or wrong about its persona. Amaryllis is about keeping society to a minimum. Auspicious Eggs is about the Catholic Church and its involvement the reproductive system. All of these stories have harsh endings if an individual can't do something to meet society's specifications about reproduction rules.

What will happen to the egg when a student tests osmosis with 3 different soultions in a cup.The student is trying to see or find the effects of osmosis on an egg.Osmosis is the movement of water molecules through a selecfively permeable membrane. Diffuision is when something spreads more widely and equilibrium means when somethings is at rest due to equal opposite forces. The student wants to find out if the egg will shrink, fill up, or change in any way.

Let's start by looking at how important water is and what it does for our bodies.

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

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

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

This is one late springtime camp never like other. At this actual minute younger scientist, you have the opportunity to take place a great burrow at a prehistorian camp, nevertheless there's a significant catch: you get the chance to assist jazz up real dinosaurs! Reveal the old-fashioned fossils to locate just what dinosaur is covering in the planet.

4.15. The purpose of this investigation was to use our knowledge on osmosis and diffusion and apply it to a de-shelled egg and see how it reacts being submerged in a sodium chloride solution. The hypothesis was that the egg would expand and increase in both size and weight this is proven correct in the table of

It is widely accepted by most Paleontologist that all dinosaurs laid eggs. However, when it comes to how they cared for them and what the eggs looked like there is extremely large variety between different species. Being able to understand the differences in dinosaur eggs will lead to a better understanding of the reproduction of individual dinosaur species. The eggs themselves had to contain distinct characteristics as to give the offspring the best chance of survival. The shell of the egg needs to provide calcium to the developing skeleton, but be able to allow for gases to easily without affecting its hatching. This was achieved through pores on the surface of the shell (Horner and John 2000). As with all features the thickness was

The shells are the part of the body of a marine animal, in most cases the exoskeleton. The word shell is often used to refer only to the shells of marine mollusk, mollusk shells but it can also be used to mean the shells of a wide variety of marine animals from different phyla. The composition of seashells have three distinct substances involved: the outer layer of the horny substance conchiolin, the intermediate layer of calcite, and the smooth inner layer composed mainly of calcium calbornate. The blood of a mollusk is rich in a liquid form of calcium. A soft outer organ called the mantle concentrates the calcium in areas where it can separate out from the blood, forming calcium carbonate crystals. The mantle deposits sheets of the crystal in varying thickness. The individual crystals in each layer vary in shape and orientation.
