INTRODUCTION: The purpose of this experiment was to test the validity of the Law of Reflection and Snell’s Law (Also known as the Law of Refraction). Reflection is defined as the reversal in direction of a particle stream or wave upon encountering a boundary. The law of reflection states that the angle of reflection and angle of incidence are equal‚ with each angle being measured from the normal to the boundary: Refraction is defined as the bending of light that takes place at a boundary between

Phillip Zimbardo’s Stanford Prison Experiment: Ethical or not? Chase Clark University of Massachusetts‚ Lowell Abstract The research conducted in this paper consists of solely the Stanford Prison Experiment‚ which was originally conducted by the social psychologist‚ Phillip G. Zimbardo. This experiment replicated a real prison that took students to participate in it. Students role-played the prisoners themselves‚ and prison guards. It was conducted in the basement of the psychology department

In our society‚ there are many social norms we are expected to abide by. These unwritten rules and standards of behavior often go unnoticed‚ leaving society to take them for granted. We only become truly aware of the norms of society when they are actually violated. When a violation occurs‚ those who continue to conform may respond with positive or negative sanctions‚ such as humor‚ alarm‚ irritation‚ fear‚ or a wide variety of emotions. Our society also relies on language as its major bases for

mammals‚ including humans. In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable amino acids called polypeptides. The aim of this experiment is to investigate the effect of changing temperature on the activity of enzymes. After experimentation the optimum temperature for enzyme activity will be established and the effects

In this experiment‚ one of the big is osmosis‚ and how it had the overall impact in this excitement a little on osmosis. Osmosis takes place when two solutions of different concentrations are separated by a semi-permeable membrane in which the solvent can pass through but not the solute. In our experiment‚ we used a sucrose solution that will be a hypotonic concentration of solute. This tells us that the solution has a lower concentration of water than does the cells. Therefore‚ due to osmosis‚ the

research experiment to study how people conformed to the roles they are given. The experiment was set up in the basement of Stanford Psychology building. Zimbardo’s goal was‚ “... to understand more about the process by which people called “prisoners” lose their liberty‚ civil rights‚ independence‚ and privacy‚ while those called “guards” gain social power by accepting the responsibility for controlling and managing the lives of their dependent charges” (Zimbardo par. 11). Although the experiment was

Robbers Cave Experiment Jamie Allen Drake University Abstract Robbers Cave experiment was completed by Muzafer Sherif in order to question whether groups are able to work together for a common goal for the whole group. Muzafer showed us through 3 stages a) In group formation b) Friction phase c) integration stage. This experiment was made up of 22 Caucasian middle class boys who shared similar backgrounds coming from a two parent home and protestant background. The boys were complete strangers

Abstract: This experiment was completed with the intention of testing if two specific plants were allelopathic. Allelopathicity is defined as “They are allelon which means "of each other"‚ and pathos which means "to suffer". Allelopathy refers to the chemical inhibition of one species by another. The "inhibitory" chemical is released into the environment where it affects the development and growth of neighboring plants.” (Ref 1) Introduction: Have you ever wondered why certain plants do
