Hypothesis: I predict that when the egg is placed in the vinegar solution, the calcium carbonate shell will dissolve. I predict that when the egg is placed in a hypertonic solution such as corn syrup, it will crenate. I predict that when the egg is placed in a hypotonic solution such as water, it will expand. Materials: In our experiment, we used an Eggland’s Best 12 Grade A Large Egg, paper towels, petri dish, triple beam balance, clear plastic cup that served as a beaker, vinegar, corn syrup, and water. Methods: On the first day, we weighed the petri dish and then our egg on the petri dish so that we could get the mass of the egg itself, both on the triple beam balance. We recorded our results and observations about the egg. After, we placed our egg in the clear plastic cup and poured vinegar to completely …show more content…
We had to weigh the petri dish to get the actual mass of the egg. The petri dish that we used that day weighed 7.9 grams. The egg in the petri dish weighed 61.55 grams. We had to subtract the mass of the petri dish from the mass of the egg in the petri dish. So the original egg weighed 53.65 grams. Our observations were that it was white, oval-shaped, small, and it had small pink letters for the brand. On the second day, most of the calcium carbonate shell dissolved and there were bubbles on the top of the cup that showed that. We weighed the egg after sitting in the vinegar solution. We had to weigh the petri dish to get the actual mass of the egg. The petri dish that we used that day weighed 7.95 grams. The egg in the petri dish weighed 92.3 grams. We had to subtract the mass of the petri dish from the mass of the egg in the petri dish. So the egg weighed 84.35 grams. Our observations were that the shell was gone so it was now slightly yellow with many white streaks and the pink letters were gone. It was still oval-shaped but it was bigger in
Hypothesis: The Alka Seltzer will dissolve fastest in hot water and slowest in cold water.
Each subsequent trial will use one gram more. 2.Put baking soda into reaction vessel. 3.Measure 40 mL vinegar. 4.Completely fill 1000 mL graduated cylinder with water.
During this experiment Brine Shrimp were placed in four bowls. These four bowls contained 2 cups of either water, vinegar or a water and vinegar solution with 50 shrimp in each. Over a course of 3 hours all of the shrimp in the vinegar mixtures died. Beginning this experiment, the control group, placed in two cups of water moved around the bowl actively. This differentiated from the groups placed in vinegar solutions. These shrimp were placed in one of three bowls. In group 2 the tank consisted of one and a half cups water and a half cup vinegar. The third bowl contained one cup water and one cup vinegar. Lastly, the fourth bowl included two cups of vinegar. The shrimp in the control group were the most active. The shrimp in these bowls moved
3. Fill up the 50 milliliter beakers all the way up with deionized water. After, use your scopula to scoop out a small portion of one substance and put in into your beaker. Then put your hot plate onto medium temperature and rest the mixture onto the plate.
There were approximately 8x the amount of pillbugs on the water side compared on the vinegar side. Many sources of error could have occurred during the experiment, however. One possible source of error was that about half of the pillbugs were actually sowbugs, an isopod crustacean that has extremely close relations with the the pillbug. The main difference is that sowbugs do not roll up. This could have been a source of error because the difference in the two species may have attributed to the preferences of the isopods in the experiment. A second possible source of error was uneven lighting on our experiment. We gave our best effort to control the lighting and background as much as possible so that the experiment would not be affected, but there could have been something that was overlooked because a classroom environment is not the easiest thing to control. The last source of error was something that could not have been avoided. As time goes on, the pillbugs could have slowed down their movements compared to when they were first dropped into the bin due to their natural
I didn't boil the egg because I wanted to keep the shell fragile like our teeth. I then filled four bowls with 1 cup of each drink. I then put the egg shell in the bowl and covered it so the shell was covered with the drink. I came up with 48 hours total for the eggshell to sit in the drink, because I estimated a person drinking 1-2 cups of drink a day for a month. So, I let the eggshells sit for 24 hours first. When I checked them, the Grape Juice and Coke were tied for first place in staining. Second was the Coffee, and Third was the Tea. I put each eggshell back in the same bowl and waited another 24 hours . This time when I took them out, The Grape Juice was first, Coke was second, Coffee was third, and Tea was fourth. I then took a toothbrush with Colgate whitening toothpaste and brushed each egg shell. I then rinsed them with clear water and let them dry. After they dried, I compared them to a teeth staining chart I found online. The Coffee eggshell was stained the most, Coke was second, Grape Juice was third with scattered staining, and Tea was fourth with almost no staining. I chose to brush the shells because while researching, it said you shouldn't brush your teeth after drinking drinks like this because this is when it damage teeth
The experiment could have gone many ways with different possible results. There are a couple of changes that might be made to make the experiment better. One change would be to use something else instead of bananas for eggs. Bananas have a strong flavor, so maybe using applesauce for oil or avocado for
I am going to tell you about the planning and result of my egg drop project. First I took a green container and surrounded the outside with clear duct tape. Secondly I taped the inside which was very tricky. I then put bubble wrap in and taped the egg to it. I taped the top so the egg couldn’t fall out. I named the egg Aidan and have drawn a face on it.
To determine if the number of candles lit and how much the water rises underneath beaker is related.
Boil 9 eggs (it doesn’t matter the size, just make sure all are the same size)
1/10 spoon of salt was added to the egg. The egg was stirred by the egg beater until it became a pale yellow and homogeneous fluid. Water was then added to the beaten egg. The volume of water was about 1/6 of the volume of the beaten egg. The mixture of egg, salt, and water was stirred by the experimenter for 20 seconds. Second, a frying pan was prepared for cooking the egg. The bottom of the pan was covered with a thin layer of olive oil and heated over medium heat for 1 minute on the cooking stove. The beaten egg was then poured into the pan. The egg was constantly stirred until it became fluffy and no liquid was present in the
The crystals that were growing at room temperature ended up having the smallest weight out of the three. Its average weight was 28 grams. The crystals growing in the ice bath had the second highest average weight of 29 grams. The crystals that grew the largest was the one in the fridge. It ended up having an average weight of 37 grams.
Egg Albumen Experiment The purpose of this investigation is to establish which is the lowest concentration of Copper (II) Sulphate solution that will denature a sample of egg albumen (egg white) at room temperature. The base of the reaction is the globular protein (albumen) being denatured by a heavy metal (Copper (II)), the copper (II) reacts with the NH3 group causing it to denature, this means the proteins' secondary and tertiary structures are being altered and refolding into different shapes, this resulting in a change from the substance being clear to turning opaque.[1] As the concentration of the denaturants increases more folding and changing of shape will occur and therefore more denaturing will occur and at a faster rate. From this I can predict that that lowest concentration of the solution is approximately at 0.03m solution.
Examine 3 different natural selections using brine shrimp and salt solutions. It will test the hatching viability of roughly 20 brine shrimp eggs in three different NaCl solutions over the course of 48 hours.
The materials that were needed to conduct this experiment was a concrete or lead object, a scale to weigh the object, string, empty bottles, sea water, a graduated cylinder for measuring the water accurately, and buckets filled with sea water.
