the potential energy is constant along the chain and sharply rises to infinity at the ends. Therefore‚ we can replace the electron system by free electrons moving in a one dimensional box of length . Objective: The purpose of this experiment is to obtain the visible spectra of several cyanine dyes and then interpret them to a simple model of the electronic structure of the π system: the Particle in a Box. Theoretical Model “Particle in a Box” In the Particle in a Box model

The Stanford Prison Experiment – Phillip Zimbardo Introduction Headed by Phillip Zimbardo‚ the Stanford Prison Experiment was designed with the aim of investigating how readily people would behave and react to the roles given to them within a simulated prison. The experiment showed that the social expectations that people have of specific social situations can direct and strongly influence behaviour. The concepts evident in the Stanford Prison Experiment include social influence‚ and within that

Investigation: The Stanford prison experiment was originally intended to run for a fortnight. However it lasted only 6 days and was ended earlier than initially planned due to the terrible living conditions and psychological problems that developed as the ‘inmates’ and ‘guards’ interacted.. The experiment was run by Philip Zimbardo‚ Craig Haney‚ David Jaffe‚ and W. Curtis Banks. The test subjects were young male college students that were chosen from 75 volunteers. The volunteers had replied to

Factors that affect the rate of fermentation are the nutrient availability and the concentration of that nutrient. In the Barfing Bag experiment‚ our control group which was granulated sugar worked the best against splenda‚ artificial‚ and stevia which a sugar substitute that comes from a plant and has 0 calories. In the barfing bag experiment we had three bags with yeast and then we added different types of sugars to test which type of sugar creates the most carbon dioxide or which bag inflates

Silver Mirror Experiment Background: This experiment was first conducted by Bernhard Tollens‚ it is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. An aldehyde is a compound containing a formyl group (CHO).The experiment involves diamminesilver complex and a chemical reagent (also known as “Tollens’ reagent”) which in this case is glucose. In a successful experiment a reflective silver metal should precipitate‚ with characteristics identical to that of a mirror’

Risk Taking Experiment A. There are many risks in life one must take. I had several options to explore for this experiment such as going on a drop roller coaster‚ sky diving‚ and killing insects. I thought that sky diving would be fun‚ but I am not old enough to do because the minimum age requirement was eighteen years old. I also explored the idea of killing insects especially spiders which I hate the most‚ but I thought going on a drop roller coaster would be more interesting. B. I chose the
