THE STANFORD EXPERİMENT What happens when you put good people in an evil place? How the environment affect behaviours ‚ attitudes or beliefs of people? Philip Zimbardo was interested in this questions. Zimvardo choose a prison enviroment as the evil place.

All of the conditions in basement change for experiment such as guards uniform ‚ prisoners overalls‚ grates ‚ dark cell etc.Zimbardo

The very first experiment had the hypothesis that the temperature of a burner flame can be controlled by adjusting the ratio of gas to air in the mixture to be burned. During this experiment‚ my partner and I gathered our materials of the paper matches‚ straight pins‚ copper wire‚ laboratory burners‚ rubber tubing‚ tongs‚ and evaporating dish. Making sure we had our safety goggles on and the material we needed‚ we connected the Tirrill burner into the gas and lit the burner with the match‚ having

Introduction The brain is one of the most complex machines to ever exist. Many experiments are conducted to try to learn more about the brain. Within the Bransford & Johnson experiment‚ their experiment focusing on the memory aspect of the brain. They focus on schema theory which was proposed by J. Piaget. Schema is the mental framework that helps interpret information by comparing new information to pre-existing knowledge. This study was conducted in 1972 by Bransford and Johnson. The aim of

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

The problem for this experiment is how does the amount of caffeine affect the speed and performance of a mouse. The hypothesis is if the amount of caffeine consumed by the mouse is increased‚ then the time at which the mouse completes a set obstacle course will decrease when time is a function of caffeine quantity. The amount of caffeine consumed by the mouse before completing the obstacle course is the independent variable. The dependent variable of the experiment is the amount of time the mouse

Conclusion The purpose of our experiment was to determine if reading off words in various colors helped improve memory. Our hypothesis was that color helped memory and it was in fact proven by our experiments. According to data table 2‚ the average words remembered by the white control group was 6.4‚ while the other groups with the colors had averages of 6.8 and 8.2. Our hypothesis also proven in table 3‚ where the average words remembered by the control was 4.6 and the other two groups had averages

Title Identification of Analgesic Compounds Using Thin Layer Chromatography Abstract The objective of laboratory experiment six was to identify an unknown analgesic tablet using Thin Layer Chromatography (TLC) analysis. The procedure involved preparing TLC plates‚ solubilizing standard analgesics (ibuprofen‚ aspirin‚ acetaminophen‚ caffeine) and the unknown in isopropyl alcohol (IPA)‚ and developing the plates in acetone. Rf values were calculated for each compound. The unknown tablet showed an Rf
