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 ………………………………….

so the skeletal muscle cells are supplied with more oxygen and respiratory substrates used to generate energy in respiration where it is needed. A drug that increases heart rate is called a positive chronotrope‚ and this is demonstrated in this experiment when adrenaline is used to increase heart rate in Daphnia. One of the ways adrenaline increases heart rate is through the action of what is known as a ’second messenger ’ or ’transduction component ’‚ in this case it is a chemical made in the

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.

emotionally and physically involved. Secondly he denied Richard Yacco the ability to leave. Whenever one conducts an experiment‚ all who are involved should have the right to end their involvement at anytime. Finally there was no proper debriefing‚ as well as it was argued that many left in a worse mental state then prior to the experiment. Now some may not be bothered by such an experiment in fact‚ we have seen other controversial studies such as Mailgrams’ study‚ where he was studying the conflict between

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

Discussion: First of all‚ rinse all the apparatus that being used in the experiment with hydrochloric acid (HCL) then followed with distilled water (H₂O). Then‚ prepared the saturated calcium hydroxide (Ca (OH) ₂) solution into a filter funnel and filter paper over a second conical flask. Pour 100.00mL of saturated Ca (OH)₂ solution into a beaker and pour the solution through the filter paper by flowing the solution through a glass rod. After that‚ use a thermometer to measure the temperature of

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

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
