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)

TOPIC: Spring Mass Oscillator OBJECTIVE: To determine the spring constant (K)‚ using mass system. APPARATUS: STEEL RULE SPRING STOP WATCH TAPE MEASURE SLOTTED MASS THEORY: In classical mechanics‚ a harmonic oscillator is a system which ‚ when displaced from its equilibrium position‚ experience a restoring force‚ F‚ proportional to the displacement‚ X‚ according to Hooke’s Law; F = – KX = mα ………………………………….

Feldler Psych 105 14 October 2014 Blue Eyes vs. Brown Eyes Through the eyes of a kindergarten class‚ prejudice dynamics were shown in a simple yet powerful experiment. On April 5 1968 Jane Elliot preformed the famous experiment in her classroom separating blue-eyed and brown-eyed students. She had separated them by making one eye group inferior to the other making them have certain benefits and better treatment than the other. Then it was

at a specific interval to give a range of varying speeds; these speeds could then be compared to the set speed limit on the road. The purpose of this experiment was to determine if cars on Woody Hayes Drive needed additional traffic control to reduce speeding. The sections that follow describe the process‚ calculations and answers to this experiment. Section 2 will describe the tools and step-by-step processes that’re required to replicate this study.

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

Introduction: The purpose of the plant growth experiment was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant. The plants we were testing were radishes We decided on testing the validity of Miracle Grow with radishes to determine if fertilizers are worth purchasing. Hypothesis: If the recommended amount

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

Purpose The reason for this experiment is to prove that objects of different masses‚ when dropped from the same height‚ fall at the same velocity. Apparatus - 2 Marbles of different mass‚ one steel and one nylon - Dropping Mechanism with a lever to hold the marble and pull for drop - Bee Spi (measures velocity in kilometers per hour.) - Box to catch the marble on the way down Procedure The dropping mechanism was set up‚ with the BeeSpi attached to it at 26.5” from the lever that drops

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

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide
