Mass And Volume Of An Egg In Vinegar, Corn Syrup

How will the cell change as a result of being placed in different types of liquids? In this experiment we studied and tested the effects corn syrup, vinegar, and distilled water had an egg. When placed in vinegar the egg will double in size because the egg will soak up the vinegar. When placed in corn syrup the egg will shrink in size because the corn syrup will cause the egg to throw everything out.

For the second part of your assignment, you will apply the scientific method to a real-life situation. You will select a problem that leads to a testable question, similar to the scenarios presented in Part I and explain how you would follow each step of the scientific method to try and answer the question or solve the problem. Note: you are describing only what you would do at each step; you will not be conducting the experiment.

The evidence that was collected in the experiment refuted the day one hypothesis because after the egg soaked in vinegar for 72 hours, the mass of the egg was not the same, it was greater than before. The day two hypothesis was also refuted because after the egg soaked in maple syrup for 48 hours, the mass of the egg was not greater, it was less than before. The evidence collected accepted the day three hypothesis because after soaking in deionized water for 24 hours, the mass of the egg became greater than

By the end of the experiment, it was predicted that the egg would be swollen when left in water and shriveled when left in corn syrup. Based on the data given from the table above, the prediction is, more or less, right. The egg did, in fact, shrivel up and the weight of the egg did go down as well. Compared to the beginning of the experiment where the egg had an initial mass of 81.50 grams, but by the end of the water aspect of the research the egg ended up weighing 93.74 grams, therefore, there was an increase of 12.24 grams. Using the data table the weight from the start the syrup aspect of the experiment was 93.74 grams, after being left in syrup the egg weighed a total of 57.32 grams, thus, the egg decreased in weight by 36.42 grams.

Corresponding to the previous experiment, this week’s experiment measures the participants’ ability to conduct basic, fundamental laboratory procedures. These procedures revolve around scientific measurements of volume, mass, and density. Unlike last week’s activity, this week’s experiment had a few modifications. In addition to distilled water, saltwater and an unknown substance were added. There was a total of five substances to choose from; Hexane, Methanol, Ethyl acetate, Ethylene glycol, and Dichloromethane. Part C, the unknown liquid number was four, which the average density was 0.789 gmL-1, and from looking at the chart the unknown identity was methanol. Part A, the temperature of the water was 20 oC, which was in front of the class,

Before the food lab experiment where we tested milk, crackers, bananas, and egg whites for simple sugars, starch, and proteins I expected to learn about what foods contained any of the three possibilities, if not all of them. The lab provided my group and I information afterwards that can further my education into macromolecules and biology as a whole subject. My group and I predicted that milk will contain simple sugars, crackers will have simple sugars and starch, bananas will have proteins, and the egg whites will contain proteins. If milk does contain simple sugars, during this lab when my group and I test, then the milk should turn from a blue color to a green, yellow, orange, or red color when heated. Crackers should have the same outcome as milk if it does contain simple sugars, but if crackers also have starch the crackers should then turn into a blackish color. We predicted that bananas contain protein and if so, then the solution should turn from a light blue to either a dark blue or a purple. Finally, egg whites are what my group and I finally predicted to contain proteins. If our hypothesis is correct, the solution should do the same as it does for the bananas.

We had to first gather 3 eggs and 3 cups. Put one egg in each cup then we had to get the 3 solutions that were being used for the experiment, which was mouthwash, syrup, and salt water. We labeled the cups for which solution went which what egg and then we had to measure each egg before putting it in the substance for 24 hours. To measure we got a string and wrapped it around each egg to get its circumference then we took that measurement(the circumference of the string) and converted the string to a ruler to find out the circumference.

In the Gummy Bear Lab, the scientific method is used throughout the process. The first step of scientific method is observation, in this case I observed how a gummy bear’s density will be affected. Second step, was to state a hypothesis on how the water will affect the density of the gummy bear overnight. In addition, my hypothesis stated, “ If the gummy bear absorbs the water overnight then the density will increase.” Next step was to gather materials to prepare to perform an experiment in the laboratory. The materials used were the following: a ruler with centimeters, balance scale, graduated cylinder, gummy bear, and a small cup of water. Then by using the materials, measurements of the gummy bear were recorded such as the length, width,

The table above displayed the data we figured out concerning the mass of each substance. First, we weighed the cup alone that contained the unknown substance. It weighed 3.5 g. Then, weighed the cup with the unknown substance. It weighed 32.5 g. The final mass was determined by subtracting the cup mass (3.5 g) from the cup mass with the unknown substance (32.5 g). I figured out the final mass was 29 g. Next, we weighed the cup alone that contained the aluminum. It weighed 3.5 g. Then, weighed the cup with the aluminum. It weighed 17 g. The final mass was determined by subtracting the cup mass (3.5 g) from the cup mass with the aluminum (17 g). I figured out the final mass was 13.5 g. After that, we weighed the cup alone that contained zinc. It weighed 3.5 g. Then, weighed the cup with the zinc. It weighed 19.7 g. The final mass was determined by subtracting the cup mass (3.5 g) from the cup mass with the zinc (19.7 g). I figured out the final

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.

More specifically for the experiment we will need four deshelled eggs, four beakers and distilled water with a certain percentage of sucrose, a timer, and a scale to weigh the eggs. Using the process of osmosis, we will determine the weight of the eggs after being soaked in the solution. The four beakers each had distilled water in them with sucrose but all contained different amounts. One beaker contained 0% sucrose. The other beakers contained 10%, 40%, and an “unknown” amount of sucrose. Before placing the eggs into the solution, we are to weigh each egg separately to the nearest 0.1g and record this in table. Once that step has been completed, we then place one egg in each of the beakers separately that was marked with the amounts of sucrose. At fifteen-minute intervals, remove the deshelled egg from the water inside the beaker and wipe off all the excess water. After that process has been completed, we will weigh each egg separately to see if they have gained or lost their mass/weight. Once each egg has been weighed accurately, the recorded data is placed in the table provided. This step goes on for an hour. The deshelled eggs in this experiment will increase in mass in the different types of distilled water. This lab session provided the class with the evidence that diffusion and osmosis occurs within the different types of solutions.

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.Leave both eggs in their beakers alone for 48 hours. After the 48 hours, take both eggs out of their beakers. Clean both beakers for reuse. Fill one beaker with 125 ml of corn syrup. Fill the other beaker with 125 ml of water. Lave bother eggs in their beakers alone for another 48 hours. After the 48 hours, take both eggs out of their beakers. 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. Clean up and the experiment is

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

This is the final step of the experiment. The shell-less egg was now placed into a new cup, but very carefully, as the egg was more fragile than when it was soaked in vinegar. The egg in the new cup was then covered with water. The egg sat in the water for a 24 hour time period once again. During this 24 hour time period the eggs appearance and size were once again recorded. After the time period had completed, the egg was removed from the water and was very carefully patted dry. Since the egg was now swollen, extra care was needed when holding the egg. The swollen egg was placed on the scale on last time and its mass was recorded as M3.

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