Change in Precipitation Ramon Pena BIO101 February 14‚ 2011 Dr. Richard Steiner Change in Precipitation Introduction This experiment will take course during a 300-year-time -period simulation. This experiment will consist of two islands‚ Darwin Island‚ Wallace Island and take only into account the bird population of these two islands. The parameter will stay the same‚ except for one variable; precipitation. I will record how the precipitation changes the beak size of the bird population

Many people drink sugary drinks every day‚ but really how bad is it for your teeth? This project shows the repercussions of drinking sugary soft drinks. This experiment tests eight adult teeth in eight different soft drinks for 48 hours. The results are equivalent to not brushing your teeth for two days or constantly sipping on a soft drink for more than an hour. If the sugar and acid particles are left on the teeth‚ then more acid is made by the sugar and the enamel starts to wear away. This can

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

The Stanford Prison Experiment‚ conducted over 40 years ago‚ brought these ethical issues into the limelight and remains one of the most controversial studies in the history of studying human behavior. This paper aims to define ethics‚ describe risk/benefit ratio‚ provide a brief background on the Stanford Prison Experiment‚ and evaluate the impact it has had on psychological research.

Behavioural Study of Obedience: Milgram’s Experiment M.J George Brown College #1) Obedience I think the three aspects of the situation faced by the subjects in Milgram’s study were the prestige of the university‚ the proximity of the experimenter‚ and the money paid. These aspects were the most influential in causing the subjects to obey. The influence of the prestige of Yale University was a key point to get the obedience of the subjects. People are prone to obey more

Microbial Growth of Consumable Products By Bryce Wilmott AIM: To calculate the quantity of observable microbial colonies on the surface of the Agar solid‚ as to determine the presence of microbes in consumable products i.e. yoghurt and blue vein cheese. HYPOTHESIS: Microbial growth will be present in two of the three Agar plates (those containing the food product) due to the suspected presence of microbes‚ whilst the control Agar plate (containing no food products)
