1 English 1013 10/18/10 In nineteen sixty-three‚ Stanley Milgram conducted an experiment on obedience to authority figures. It was a series of social psychology experiments which measured the willingness of the study participants to obey an authority figure who instructed them to perform acts that conflicted with their personal conscience and confronted them with emotional distress. The experiment resulted in twenty-six out of forty of the participants administering the final massive

Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the

To perform the experiment‚ first the calorimeter was filled with 100 mL of water using a graduated cylinder‚ and the temperature of the water was found and recorded. Next‚ the beaker was filled 3/4 full with water and placed on the stand of the ringstand above a gently burning

psychologist‚ and student of Solomon Asch‚ conducted a controversial experiment in 1961‚ investigating obedience to authority. 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. This experiment brought uproar amongst the psychological world and caused the code of ethics to be reviewed and ultimately changed. In the experiment subjects were asked to administer shocks ranging from fifteen volts

Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced.

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

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
