The class was then instructed to get five dry test tubes and number them one through 5. Using these test tubes they put in 10,8,6,4,2 mL of food dye and in inverse order put that amount in for dilution. From this the class was able to test the absorbance from this and calculate the…
We placed the zinc inside the beaker and slowly poured the hydrochloric acid into the beaker. As soon as the acid entered the beaker, there was a sizzling sound and bubbles started to form as we add more of the substance in. When the bubbles were forming, we could see a steam of gas coming out of the beaker. After 10 minutes, we noticed bits of zinc were floating on top of the hydrochloric acid and lining the beaker. I lifted the beaker and felt the bottom and it felt warm, which meant the reaction was still happening. After 20 minutes, we added water into the zinc and hydrochloric acid to stop the reaction and we observed a slight cloudy colour (still clear) forming as we slowly pour the water in the beaker.…
Coal mining, particularly surface mining, leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite, a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab, you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated.…
The aim of this experiment is to see which brand of paper towel absorbs the most water out of a 200mL beaker.…
(4) Add the towel sample to the water for a period of time using a consistent method.…
By now you should have a good understanding of the scientific method and its importance in contributing to scientific knowledge. Grab your lab coat and get ready to design your own experiment.…
When the volunteers were put into either the prisoner or the guard group that label determined their fate. Zimbardo stated individual behavior is largely based off of social forces and environmental factors. Thus, the prisoners were treated based off of that title and the lack of power that position held. The power behind the title of guard allowed the guards to treat the mock prisoners horribly and get away with it. The prisoners felt like they were powerless over the guards. When Zimbardo, stopped the experiment after six days because of the intense treatment he realized that he could have easily had the power of the guard or have the meekness and powerless feeling of the prisoners. In the reading, it seemed that Zimbardo realized that the…
Two future questions are; “Which shape of sponge is best for soaking up water?” and “Which oil is the hardest to clean using a sponge?”. Scientists would want to know if the amount of layers in a sponge affect the amount of oil soaked-up, and if a porous layer soaks up more oil than a non-porous sponge. These could be tested in almost the same way as the experiment…
Towels are used every day by us for a number of reasons. We use towels to clean our face, for bathing, drying our hands and body, and also for cleaning. These towels used for various purposes should be cleaned regularly and kept aside for different purposes. We should have proper bath towels to maintain the health and hygiene of our family. Towels should not shared d by other members of the family. But this carries dirt from one body to another so separate bath towels should be used by everyone. Buy bath towels for one and all members of the family. Kids have a very soft and sensitive skin .The quality of the cloth used in making the towels should be kept in mind. Rough and synthetic fibers used in making towels can make our skin rough and leave scratches on our body.…
“It is one thing to mortify curiosity, another to conquer it… (page 37)”. In Robert Louis Stevenson’s The Strange Case of Dr. Jekyll and Mr. Hyde, the main purpose of Jekyll’s experiments are to liberate himself, or in other words, to free himself from the evil part within him. He succeeds in many ways, which include the outcome of Jekyll taking the potion he created, and successfully releases his evil side through Mr. Hyde. He fails in many ways as well, including Hyde losing control and Jekyll desperately needing a purer potion.…
I would not be the kind of person who takes orders blindly whether it is from an authority figure or not. I personally would not like to be on the opposite end of this situation therefore I would find myself resisting the orders to end another’s life. Sometimes you don't have the necessary amount of time to decide whether or not what you are being asked to do is the right thing or not, and in those kinds of situations people normally find themselves making bad decisions. If it were at all possible I would try to figure out for myself whether or not the person in question actually deserved it. If I had to for the sake of those I loved or for my own life I honestly believe that I would do what is needed to ensure mine or others safety. Not because I was ordered to do so by a figure of authority but because it was the right thing to do.…
In the semiconservative hypothesis, proposed by Watson and Crick, the two strands of a DNA molecule separate during replication. Each strand then acts as a template for synthesis of a new strand.[2]…
Stanley Milligram experience was created to understand the physiological boundaries of people concerning their morals and their better judgment; whether under the direct authority or not. The objective of the experiment was to gauge how individuals respond to having the authority and carrying out duties per their job requirements, regardless if it affects their morals or way of life.…
It is hard to generalize the findings from the Little Albert experiment to other children for a variety of reasons. The main reason that stands out is the fact that there was no random sample. Watson, only used Albert in the study which did not allow for a great variation. Watson should have had two groups of children; one group being exposed to the noise and the other group not being exposed. The other issue that plays a part in this experiment was that Watson knew of Albert’s health condition. It’s hard to say whether, Albert responded in the way he did because of the conditioning or because of his brain. Problems within the experiment will lead to a false outcome. We have no means of knowing for certain whether the experiment conducted shows…
In this particular area there are few trends going on. People have been using hand towels for so many years and no new trend have developed. We…
