Environmental Science The Scientific Method Amber Steadham October 31‚ 2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical

EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

of this experiment is to study the characteristic of four different types of membrane. The membranes used in this experiment are polyamide film ( AFC 99 ) as membrane one ‚ polyamide film ( AFC 40 ) as membrane two ‚ cellulose acetate (CA 202 ) as the third membrane and PVDF (FP 100 ) that act as the fourth membrane. In order to identify the characteristic of all four membranes‚ experimental procedures should be done. The variable for this experiment is the membrane maximum inlet pressure‚ where different

The Milgram Experiment Stanley Milgram‚ a famous social psychologist‚ and student of Solomon Asch‚ conducted a controversial experiment in 1961‚ investigating obedience to authority (1974). The experiment was held to see if a subject would do something an authority figure tells them‚ even if it conflicts with their personal beliefs and morals. He even once said‚ "The social psychology of this century reveals a major lesson: often it is not so much the kind of person a man is as the kind of situation

Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

How The Scientist Discover The Interior Of The Earth Two ways that Scientist may study and find the interior of the Earth are with Meteorites and Magnetic Fields. The scientist may use meteorites to discover the interior of the Earth’s earlier solar system by studying the meteorites that arrived on the Earth. The scientist might use magnetic fields by the science advances which involves measuring the ocean and coming up with a hypothesis. Therefore‚ the meteorites and the magnetic fields all

Tribalism is a pervasive quality of the human experience. People readily divide themselves by categories such as gender‚ race‚ politics‚ religion‚ etc.‚ and establish groups based on their similar characteristics. By extension‚ people form loyalties to their group and simultaneously develop bitter rivalries with "the other‚" members that do not belong to the group. Conflict arises when two groups are competing for the same resources. The individual is pressured to remain loyal to the group in order

Tuskegee Experiment is one of the unethical Health Researches done in the United States. The way the research was conducted was against people’s civil rights. Totally secretive and without any objectives‚ procedures or guidance from any government agency. During the time that the project was launched there were very few laws that protected the public from medical malpractice or from plainly negligence. Also the Civil Rights act did not pass until the 1960’s. Before the Tuskegee Experiment in 1926
