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 ………………………………….

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

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

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

Performance (page32) 1. In this experiment‚ what might be some extraneous variables affecting the students’ test performance? 2. What might educators do to try to prevent the effect of the “dumb jock” negative stereotype on college athletes? The experiment done by Jameson‚ Diehl‚ and Danso‚ attests that a negative stereotype‚ being referred to as a “dumb jock”‚ may have negative impacts on the test performance of athletes. There were two groups in their experiment. The experimental group was exposed

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

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
