Spirit Burner Experiment Aim: To perform an experiment in the labs to determine the heats of combustion of selected alcohols and then to use this information and the gathered data from chemical data sources to determine trends in the longer chain alcohols. The Variables that MUST be controlled throughout the experiment are: • The height from spirit burner nozzle to the base of the water filled beaker • Air drafts around the room must be kept to minimum so as to keep the heat on the base of the

An Experiment on Soil Analysis Jacob Pitcher and Derrick Gillespie Chemistry Lab 112 Section 02 4/02/2013 Abstract A sample of soil was tested for possible contaminants and other information using a variety of techniques including moisture analysis‚ pH measurement‚ acid-base titration‚ chloride-ion electrode analysis‚ and flame testing. The sample had a greater concentration of chloride ions‚ no measurable CaCo3 ‚ and lower than standard moisture content. It was contaminated with KCl and

involved when two incompressible substances are mixed together. 12 experiments were performed‚ 10 involving the combination of a measured amount of hot and cold water and 2 involving the combination of ice and liquid water‚ the majority of these experiments were performed three times. The average variance in final temperature for each experiment was less than 10 percent providing proof of repeatability. Equipment used during the experiment included a gram scale‚ thermocouple‚ Styrofoam cup‚ glass beakers

Altruism: A Field Experiment Kamille J. Bernabe Master in Psychology Polytechnic University of the Philippines Graduate School Advanced Social Psychology Abstract Everyday life is filled with small acts of altruism. While we may be all too familiar with altruism‚ social psychologists are interested in understanding why it occurs. What inspires these acts of kindness? What motivates people to risk their own lives to save a complete stranger? Altruism as defined as the concern

your soul carefully‚ lest you forget the things your eyes saw‚ and lest these things depart your heart all the days of your life. And you shall make them known to your children‚ and to your children’s children.” Deuteronomy 4:9. (USHMM) Were the experiments that the Nazi’s conducted on the Jew’s beneficial or detrimental to the advancement of science? I think to understand the question we must understand the why‚ of the situation. For example Dr. Fritz Klein’s response to Dr. Ella Lingens-Reiner

In order to conduct this experiment GIY Mushroom Material was obtained. All other materials were cleaned with rubbing alcohol‚ (70% Isopropyl Alcohol). Rubbing alcohol was used because mycelium needed a sterile environment (7). Everything was sprayed with alcohol including tables‚ gloves‚ mixing glass‚ and even the air. All materials used were cleaned because it protected the mycelium from competing with other organisms. Mold could have been floating in the air or bacteria from touching the face

Abstract Ernest Rutherford’s Gold Foil Experiment was a major stepping stone one the way to discovering what the atom was really made up of. From the beginning of his research with alpha particles to his discovery of the atomic nucleus‚ Rutherford made many contributions to the microscopic world of the atom. The Rutherford Experiment‚ otherwise known as the Gold Foil Experiment‚ was the crown of his achievements‚ and it was during this experiment that he discovered the atomic nucleus. (Aydin &Hanuscin

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

Introduction Milgram Experiment Method 40 men were recruited for a lab experiment investigating “learning”. In exchange for their participation‚ each person was paid $4.50. After the WWII‚ Stanley Milgram a psychologist of Yale University posed a question‚ “Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices? These men were introduced to another participant who were actually actors. These men were given role

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
