What Happened To An Egg Cell's Mass

In this experiment, the question that was asked was, are elephants afraid of mice? The hypothesis is if a mouse is placed near an elephant, then the elephant will be frightened. The experimenters traveled to an African safari to perform the experiment with their test subjects (an African elephant and a white mouse). They hid the mouse in elephant dung and rolled over the dung whenever elephants passed by. At first there was speculation that the elephants might have been startled by the moving dung. But, after retesting the experiment they realized that was not the case. Only the presence of the mouse seem to stop the elephant in their tracks. The independent variables in this experiment were the methods (such as the elephant dung, the string, the mouse) used as well as the breed of the elephant and mouse. The dependent

In this lab, we soaked a gummy bear in water for twenty four hours to see the effects osmosis would have on it. When we got our gummy bear we would take its measurements and soak it in water. After twenty four hours we would take it out and record the measurements again and find the percent change. The question that we addressed in this lab was, what would happen if you soaked a gummy bear in water for twenty four hours? I hypothesized that after this time the gummy bear would increase in size. I predicted this because the water is hypotonic to the gummy bear, so the water would diffuse into the gummy bear causing the cells to swell and increase in size. The control group in this experiment was gummy bears that were not soaked in water because

Although there were no drugs used in the Stanford Prison Experiment, there was physical and mental abuse used in the experiment. The Stanford prison experiment started in 1971 and was conducted by psychologist by the name of Phillip Zimbardo. The Stanford Prison Experiment continues the steady theme of controversial psychological experiments because of its lasting impacts on the participants. In the experiment, Zimbardo tried to prove idea of Dispositional factors. Dispositional factors are when the personality traits or the motives of people change from the different circumstances at which they are involved (Phelvin 2014). The author of the journal, Andrew Phelvin, discussed the experiment in depth and where the idea had lacked. Phelvin explains

Going into this experiment, it can be expected for the weight of the egg to decrease as the solution has greater amounts of sucrose, making the solution hypertonic meaning the weight of the egg will

I look up to Colbert in his comedic standing and his amazing performances he gives. Zimbardo starts off the interview by giving Colbert a Lucifer T-shirt; which I thought to be pretty symbolic in of itself. Because during the interview, and as the discussion progressed Colbert took on this kind of “devil 's advocate” attitude towards Zimbardo. Cracking jokes and claiming that the title of the book turns the argument on its head. I found it quite hilarious and quite entertaining. But I also felt as though Zimbardo got so caught up in trying explain his title of the book, because of Colbert, that he was not able to fully explain what he meant by the “Lucifer Effect”. Also, because of the time stipulations, and after this back and forth between the two, Zimbardo had no time to talk about any of the other experiments in this interview.

Diffusion is when molecules moving freely through the space, it requires no energy. An example is when someone sprays a febreze in an area then the molecules slowly spread in the area.

The egg-speriment was one of the ways to observe how the cell membrane works with different liquids entering and leaving.The egg is a model of the cell membrane that is soaked in vinegar for Days 1 and 2, water for Days 3 and 4, food coloring with water for Day 5, salt water for Day 6, and finally Arizona Tea for Day 7. My hypothesis was when the egg is soaked in vinegar, it will make the shell rougher, water will make it soft, food coloring will make it colorful, and salt water will make it a rocky shell. In this egg-speriment, the manipulated variables is the liquids, the responding variable is circumference, and the controlled variable is the egg.

Problem: Will the mass of an egg change after being soaked in distilled water or corn syrup for 24 hours?

One of the themes in Exhalation by Ted Chiang is the scientific method can reveal truths about existence. The scientific method is like a fortune teller. It can give us the answers that we did not have before. In the short story, the world is filled with a race mechanical beings. Curiosity builds as time appears to be moving faster even though there is no malfunctions with the clocks. One scientist decides to take upon the task to figure out what is going on and dissects his own brain. Through the scientific method, the scientist discovers that because the atmospheric pressure rising that the air passing through their brain is slower. The slower the air passing through their brain, the slower their brains perform. This discovery led to the

There are limitations/doubts about Mrs. Leonardos ' conclusion. In the data ,it shows two different densities which might mean she is using two different type of clay and it shows this is not a controlled experiment since in the background it states "... she begins to wonder if each differently sized piece has the same density." So if she is trying to see if the "size" of a clay will affect the density so changing two factor results in a uncontrolled experiment. Also in Mrs. Leonardos ' conclusion she didn 't use text evidence or any evidence from experiment supporting her claim. According to her conclusion it states "Also I measured the mass three times for each sample". A good conclusion will have

In the depths of Frigid, Alka, there lived a man named Humphrey Dumpty. He was oddly round and very obese but was always vivacious and full of tons of energy. It seemed as though he was like a slinky, jumping playfully, because he gamboled everywhere. Humphrey seemed very excited one day when there was a religious ceremony because he was chosen. Every week one of the local people in their tribe, called the “Eggs”, are chosen to go to “heaven” and are chosen by a mystical hand that drops from the sky and ascends them into what they think is heaven. The choosing of a specific egg is random but it was Humphrey’s fate to travel with the hand to the unknown. The hand of their god came down with great force and clamped Humphrey into the palm of his sandpapery hands. Once the god gripped Humphrey firmly, he yanked him into the sky.

When using gas in the egg drop challenge, it spreads the amount of energy transferred from the ground to the egg. Making the energy from the ground to the egg less, because if you look closely at a balloon filled with air. When it hits the ground, the gas in the balloon spreads out inside the balloon, and then contracts back. The solid object (the egg) on top of the balloon will sink into the balloon, because it’s a solid and heavier than the gas in the balloon. Let’s say you have an egg that weighs about one pound, you have to build a sculpture that slows down something moving at 9.8 meters per second. A sculpture that can stand the energy from a one pound object falling

The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis. Being, if hot and cold water were combined, then the cold water would move beneath the hot water because cold water is denser than hot water.

We decided to test the volume of the starch after a 24 hour period. We decided to test the initial vs. final volume of starch because if theory one was correct then the red blood cell would appear bigger, but the volume of the starch would not rise. If theorem two was correct then the water would go into the red blood cells anthe the cells would be prodigious compared to the original size and the volume of the starch would rise. If theorem one was correct then the red blood cell would just appear herculean, but not be growing in volume. Overnight the starch volume increased by a little less than 1 ml proving our hypothesis that water molecules move into the cell because of the concentration of the water is greater outside the cell than it is inside the

Trial 4 and 5 were still wet and crumbled and the top came off on Trial 5
