The purpose of this lab was to show us what will happen to the egg and vinegar when you combine it. When they were combined, a chemical reaction happened, and carbon dioxide is released, that’s why there were bubbles around the egg. After what happened, the eggshells were dissolved. The purpose of this lab was to show us what happens to the egg (that was in vinegar), and corn syrup when you combine it. The egg that was in the corn syrup overnight was shriveled. The purpose of this lab was to show us what will happen when we soak the egg in the tap water overnight. When we soaked the egg in the tap water overnight, the egg appeared to be swollen. The egg also gained mass because the egg has less water concentration. The purpose of
The purpose of this project was to understand the forces, momentum, and energy a contraption would experience during an impact from a pendulum at 5, 10, 15, 20, and 25mph. The project was required to hold and protect 2 raw large Grade A eggs from each pendulum impact respectively.
A hypertonic solution is a solution in which there is a higher amount of solute concentration than in the cell. This also means that there is less water concentration than in the cell. Finally, we have a hypotonic solution. A hypotonic solution is the opposite of a hypertonic solution, in that it has a lower solute concentration than the cell. Since it has a lower solute concentration, it has a higher amount of water than the cell. All three of these solutions produce very different results when a cell is placed into them. If a cell (or in this case, deshelled eggs) is placed into an isotonic solution, there will be no change in the weight of the cell because no water will have entered or left the cell. However, if a cell is placed into a hypertonic solution, the cell will lose weight because water will leave the cell and go into the solution. As a result, the cell will shrivel up. This happens because in a hypertonic solution, there is more solute than water. And in an isotonic solution, the cell will gain weight because water will rush into the cell from the solution. Again, this happens because there is more water in the solution than solute, so the
During the first day, we weighted the egg and put the vinegar in the cup. Then, we let the vinegar sit on the egg for 24 hours. The next day ,day 2, we spilt out the vinegar ,and added distilled water. We also weighted the mass of the egg ,and described the appearance of the egg on the data chart.
Place one egg in a beaker. Fill this beaker with distilled water to just cover the egg. See Figure 1. Note the appearance of the water at this time and record your observation in Data Table 3. CAUTION: Be careful to avoid breaking glassware.
The Solution inside the burette was unveiled slowly and mixed together with the Acid “A”. The flask was swirled continuously to ensure the Sodium Hydroxide is thoroughly mixed.
To conclude from the results of the experiment, the hypothesis, which was that the creature in water would double in size, while the creature in Sprite would not grow as much, was correct. Both creatures doubled in length. However, the creature growing in water gained more mass than the creature in Sprite. During this experiment, it was learned that water is more absorbent than Sprite. Much information was gathered, and reliable answers were gained from the tests
Dr. Purreau began another examination of the egg speaking while Mr. Lincoln recorded his findings. “The chamber’s thick stone walls has maintained an adequate temperature so it appears the delicate egg is in purrfect shape. Keep that water bucket near in case the temperature rises.”
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.
My experiment was if an egg was changed by cooking or freezing it will it affect how far it would fly. So I did the tests and my hypothesis was wrong. The frozen egg did not fly the furthest, the raw egg did. The raw egg every time went about 1-2 feet more than the frozen egg did. I think this is because when I froze the egg it gained weight and the raw egg stayed the same. This was enough to make the frozen egg not go as far. In fact the frozen egg flew the least amount of distance except for on the first launch where it came in second. This Experiment change but modified to be more exact by moving it into an indoor facility. This will help with not having to deal with wind or any other weather conditions.
High-fructose corn syrup is fructose produced from corn and concentrated for use as a sweetener for such commercially made food items as fruit-flavored drinks, carbonated beverages, baked goods and spaghetti sauce. High-fructose corn syrup is close to naturally occurring fructose found in fruits and vegetables, but this sweetener is slightly higher in fructose. In addition, the fructose is "free," meaning it is not bound to glucose the way it is found in nature. While HFCS serves as a cheap and readily available sweetener, it has also been linked to the epidemic of obesity that has plagued the world since shortly after HFCS was introduced to the market. Though there are likely many causes for the obesity crisis, this discussion will focus
Pasteurization of eggs is a process in which the egg is heated to a specific temperature and kept like that for certain amount of time. Whole egg stays at 60ºC for 3,5 min, and then it is immediately chilled on ice bath and refrigerated under 4ºC.
The purpose of the project was to determine the effect of coffee, tea, or soda on the tooth enamel. The project was to determine which drink causes more damage to the tooth enamel. The hypotheses of the project were that coffee would stain your teeth. The eggs that was left in the tea or soda I thought would be less stain than the coffee. The egg that was left in the coffee will look more stain than the tea or soda, but then it turns out the egg in the Coca-Cola was stained more than the egg left in the coffee or tea.
my “bouncing egg” experiment, I have to put a hardboiled or non-hardboiled egg in vinegar for 1-2 days. While the egg is in the vinegar, the vinegar eats away the shell and toughens the membrane so that it can “bounce”. The acetic acid in the vinegar breaks apart the solid calcium carbonate that’s in the shell of the egg. The calcium ions float free (calcium ions are atoms that are missing electrons), while the carbonate goes to make carbon dioxide—the bubbles that you see.

Whenever my mom cooks I kinda wonder, why does liquid smell? How do different types of substances (Vinegar, Water, Vegetable oil) affect the outer eggshell? Well, I'm here to put it to the test. As I thought of many liquids my mom cooks with (Water, Vinegar, and Vegetable oil) I started to think of the smell, “huh, why does vinegar smell so sharp?” Well, I then went on the internet and found out that vinegar contains acetic acid which makes vinegar have its strong taste. Then I thought, does this mean it actually doesn't have that much of different chemicals?
(Cliffnotes) Osmosis played a really big role in the second part of the experiment. One of the beakers was filled with water and so was one of the dialysis tubes and both reacted with sucrose. When particles move through the membrane, whether they go in or out, the cell will either begin to shrink or grow, and can grow so much that it bursts. If a solution gains water it is called a hypertonic to the solution on the outside. If the opposite happens then the solution is hypotonic. When an equal amount of water particles are transferred between both solutions then they are both called isotonic solutions. (Lab notes) Dialysis is the process in which particles, that are different sizes, are separated using a selectively permeable membrane. In the experiment we used the dialysis tubes to test the permeability of water, sucrose and
