Flyne Anderson Experiment done - 30 September 2012 Report submitted - 02 October 2012 Chemistry 111 - Experiment 4 : Properties of Gasses Purpose: The purpose of the experiment is to learn about the properties of gasses‚ and identify them by their physical and chemical properties by combining different elements and observing how they react with each other‚ and outside influences. Materials/Procedure: I gathered my materials from the material list and set up my data table. I combined the zinc

The stanford prison experiment Assignment #3 Watch the video on the Zimbardo Stanford Prison Experiment available in the Webliography (Quiet Rage http://topdocumentaryfilms.com/quiet-rage-the-stanford-prison-experiment/). In your Threaded Discussion‚ worth 20 pts‚ post your thoughts regarding the following discussion questions excerpted from Zimbardo: 1) Was it ethical to do this study? Was it right to trade the suffering experienced by participants for the knowledge gained by the research
Premium Stanford prison experiment Milgram experiment
Milgram’s experiment in 1960 by social psychologist Dr. Stanely Milgram’s (1963‚ 1965) was a controversial experiment. He researched the effect of authority on obedience. I don’t think the scientific community overreacted to this experiment because it is unethical to reduce subjects to "twitching shuttering wrecks". Though the human mind is amazing strong we still do not know its breaking point. For interviewers to carry out the kind of experiment they did‚ they have to be willing to face the consequences

damage to 14 % of its forest trees. In this experiment‚ I will find out what consequences acid rain has on the germination and subsequent growth of cress seedlings. I will use cress seedlings‚ which germinate quickly and can grow a few centimetres in a matter of days and sodium metabisulphite‚ which reacts slowly with water to produce sulphur dioxide gas. The seedlings will have to be in an enclosed system so the sulphur dioxide does not escape. The experiment is a simulation trying to model a powerstation

PLAN OF INVESTIGATION Fundamental Science Salt water egg experiment Result Some objects float on top of the ocean‚ and other objects sink to the bottom. Why? In this salt water egg experiment we can find a solution for this question. It was noted that to make the egg float salt is needed to dissolve into fresh water. When the egg was lowered into the fresh water container it started to sink. But when salt was added to the container the egg started to float. Adding salt

1932‚ the United States Public Health Service (USPHS) conducted an experiment in Macon Country‚ Alabama‚ to study the progression of syphilis in black males known as the “Tuskegee Syphilis Experiment”. During this experiment‚ medical professionals intentionally withheld treatment for syphilis after deceitfully promising these volunteers beneficial treatment to help combat the disease. Until this day‚ the Tuskegee syphilis experiment is an infamous clinical study in America’s history that delineates

During World War II‚ a number of German physicians conducted painful and often deadly experiments on thousands of concentration camp prisoners without their consent. Doctors are looked at as the saviors of mankind‚ the healers‚ and caretakers of our utter existence. Even dating back to ancient civilizations‚ as they revered to doctors as having “special power” to protect life. The practice of medicine by the Nazi doctors is both outrageous and shocking‚ violating the trust placed upon them by humanity

Experiment 1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane
