carry out the experiment. Firstly‚ varying the length of boiling might not be the best method to determine the amount of calcium ions. If time permits‚ I could perhaps investigate other variables such as pH‚ surface area and concentration and their effect on calcium leaching. Moreover‚ I could also use other types of fish soup stocks and compare to determine which soup has more calcium in it. Lastly‚ I have purchased “cleaned” anchovies from the supermarket to carry out this experiment‚ where the head

Background Information The goal of this experiment is to measure the percentage of oxygen in air samples and this project will show an interesting way of doing that. The method depends on atmospheric pressure and a chemical reaction that removes oxygen from the air. I will find out what kind of chemical reaction can

“serious offenses” and showering them to remove their germs and lice) could certainly without a doubt cause the detainees to feel embarrassed and confused. Not only would this be degrading for them‚ it would also serve as a catalyst for psychological change. It would be at this time that the new inmates begin to really feel as though they have done something to deserve this kind of treatment. The prison attire the inmates had to wear was also part of this psychological catalyst. It probably left the

In 1971‚ The Stanford Prision Experiment was performed in order to see behind two contrasting behaviors that humans can show in a power driven institution. The point was to understand aggressive behavior typically shown by guards or people in the position of power using it to hold reign over the prisoners who in turn respond with submissiveness‚ and see how this relates in real world situations. Achievement of conclusion was the information gathered by the role play of students in an exercise of

Experiment 6 titled “Organic Chemistry” and the purpose of this lab is to get familiar with some organic functional group and test certain reactions of selected functional groups. To do the first part of the experiment (combustion test)‚ instructor demonstration in hood‚ and record the observation. Part A (combustion of toluene) pour 1 milliliter of toluene into a evaporating dish and ignite it with a flaming wood splint. Most importantly put the flame with a watchglass.

8. Was this a true “experiment”? If so‚ what was being tested? In the short story "Dr. Heidegger’s Experiment"‚ by Nathaniel Hawthorne‚ rather than observing the effect on people of the water from the Fountain of Youth‚ there is a true experiment behind. Though the narrator spends chunks of description on how the water changes people’s appearance and action‚ the inner human nature is what it really tests. As the doctor said before the experiment‚ "it would be well that‚ with the experience of

For the seventh experiment we will be performing different type of test to see how different chemical react with each other. The first experiment will be a demonstration the professor will give to the class. the first experiment you will be performing will include a test tube you will add a couple drops of dilute hydrochloric. you will add this to five little pieces of zinc metal. In next experiment you will performed you will put 2 ml of 3% hydrogen peroxide solution in a test tube .you will also

INTRODUCTION A false memory is the memory that did not actually occur‚ but looks like real to the person which recalled it. We tend to change the layout or embed things in our memory that have happened in the past or heard about them later. In reality everything we recall in our memory had not happened but our brain replaces and adds lost information from previous and related events. True memories can often be differentiated from false memories by their vividness: false memories are more "pale" and

EXPERIMENT 5 TRANSVERSE STANDING WAVES A string attached to a turning fork is set vibrating at the same frequency as the tuning fork. The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY
