The main focus of this experiment was to find the relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the

The Afterlife Investigations: The Scole Experiment “Best evidence of life after death ever.” This is what this documentary film is pointing out. Is there really a life after death? Well this film makes me believe more that there is indeed a life after death. However‚ how can scientific evidence explain life after death? Now this film showed me how. The ninety-minute documentary film is about the Scole Experiment‚ which is a five-year investigation into life after death. It is conducted by

Individuals may change their behavior due to the attention they are receiving from researchers rather than because of any manipulation of independent variables. The Hawthorne experiments took place from 1927 to 1933 in the Hawthorne plant of Western Electric. They wanted to test scientific management. The experiments were held by Elton Mayo‚ and a few of his colleagues. The experiments began as a series of productivity studies from

The nature of memory: STM‚ LTM and Duration Duration of STM One of the key differences between the concepts of STM and LTM is duration. “Duration” refers to how long a memory lasts before it is no longer available. Short term memories don’t last very long. An example of STM in action would be trying to remember a seven-digit phone number that you have just been given. This is maintained in the short-term memory by REPETITION until the number is dialled‚ and then fades once the conversation

So if you want to try just do what we did. That is our experiment. Why this happened because the Alka-seltzer had a chemical reaction beacuse of some powder on the outside of the alka-seltzer so the bubbles carried the food coloring up to the top of the bottle

The objective of the experiments is to see if mold will grow on bread if it has water. Molds are found everywhere. They are a type of microscopic fungi that lives on organic matter. They can be found both indoors and outdoors. No one knows how many species of fungi exist but estimates at least three hundred thousand or more. they have been on this earth for millions of years and believe to grow where there is moisture. According to the U.S.D.A eating bread with mold can cause allergic reaction and

The purpose of this paper is to elaborate on the Tuskegee Experiment based upon previous international study‚ it will also state the original study and where did it originate‚ the purpose of the study and the results. It will also state who or what were the principal investigators‚ the participants (gender‚ race‚ age)‚ why and how did this study end. The original study of the Tuskegee research was a disreputable medical experiment carried out in the United States between 1932 and 1972‚ in

THE SUBJECT MATTER OF EXPERIMENTS A well-designed experiment tells us that changes in the explanatory variable cause changes in the response variable. More exactly‚ it tells us that this happened for specific subjects in the specific environment of this specific experiment. No doubt we had grander things in mind. We want to proclaim that our new method of teaching math does better for high school students in general or that our new drug beats a placebo for some broad class of patients. Can we

ABSTRACT The study us experimenters re-conducted was based on Norman Triplett’s study of social facilitation and how social presence or encouragement improves an individual’s speed and consistency in their performance. The experiment was replicated in using several trials for accurate results and was split into two stages: a mental challenge and a physical challenge. The two male and two female participants ranged from ages 15 to 17 years old. For the mental challenge‚ each participant was pulled

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which
