ABSTRACT The study us experimenters re-conducted was based on Norman Triplett’s study of social facilitation and how social presence or encouragement improves an individual’s speed and consistency in their performance. The experiment was replicated in using several trials for accurate results and was split into two stages: a mental challenge and a physical challenge. The two male and two female participants ranged from ages 15 to 17 years old. For the mental challenge‚ each participant was pulled

Daphnia Experiment Report 1. Introduction Caffeine is found in many plant species‚ where it acts as a natural pesticide. It is found most commonly in cocoa‚ tea and coffee‚ but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans‚ caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure‚ restlessness‚ insomnia and anxiety which‚ in

After watching the Milgram experiment and the abuse that occur in Abu Ghraib prison. It is clear that leadership roles and authority position can both influence people to do thing that are harmful and bad to others. Leadership focuses on gaining people to follow them and is more based on free will. While authority has the power to tell people what to do. In the Milgram experiment many people back up why they continue administering shocks by stating‚ “Because an authority figure was telling them

given crop? In our experiment‚ we examine the effects of water on corn. Corn is a vital crop to North America‚ and there is a wide draw to maximizing crop yields. To determine the effects of different amounts of water‚ we tested plants with various watering times according to a schedule. All of the plants experienced all of the same conditions‚ except for the quantities of water

prison make the inner demon come out in the prisoner/guard or is the prisoner /guard already wired that way? The Stanford Prison Experiment was a study of the psychological effects of becoming a prisoner or prison guard. This experiment was led by a psychology professor named Philip Zimbardo‚ he had the help of a team of researchers. The purpose of this particular experiment was to induce disorientation‚ depersonalization‚ and DE individualization in the participants. After a period of time behind bars

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
