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

is still open to controversy. Does a dose of caffeine heighten one ’s mental performance‚ or does it achieve the opposite? Many experiments have already taken place in order to discover how caffeine effects a person ’s mental performance. In the Radiological Society of America ’s annual conference in December of 2005‚ Florian Koppelstatter reported an experiment in which he used functional magnetic resonance imaging(fMRI) to determine how coffee effects brain activity.

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

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 Tuskegee Experiment In 1932‚ in the area surrounding Tuskegee‚ Macon County‚ Alabama‚ the United States Public Health Service (PHS) and the Rosenwald Foundation began a survey and small treatment program for African-Americans with syphilis. Within a few months‚ the deepening depression‚ the lack of funds from the foundation‚ and the large number of untreated cases provied the government’s reseachers with what seemed to be an unprecedented opportunity to study a seemingly almost

Salinity Experiment Aim To determine a method of measuring a soil sample’s salinity level in order to measure 3 samples’ salinity level. Hypothesis I think that by running a current through a salt solution and measuring the resultant amperage‚ a pattern in the recordings will help find a soil sample’s salinity level. Variables Controlled Amount of solution (100 mL)‚ supplied voltage (4V)‚ amount of soil (50 gm) & water (150 mL) in soil sample’s solution. Independent Amps recorded
