Extended Experimental Investigation Year 11‚ Microbiology BYRNES‚ Olivia Extended Experimental Investigation Year 11‚ Microbiology BYRNES‚ Olivia Abstract The following report discusses whether the bacteria E.coli K12 are able to gain resistance to nickel and aluminium over generations. It discusses the importance of bacteria and how it is used throughout everyday life. It discusses that some bacteria is used for human applications and shows how it can be helpful in certain situations

Social Psychology Experiment Replication (Group Project) An experimental Study of The Door in the Face Technique Date: 28/4/2009 ABSTRACT Door in the face technique is a persuasion method in which a requester first asked an extreme request (which was refused) and then a smaller request. Our experiment was conducted to test the effectiveness of door in the face technique for inducing compliance with different strategies when giving requests. Hong Kong Community College

however‚ sometimes we actually remember a misrepresentation of what’s really occurred. This is known as the misinformation effect‚ where misleading information distorts our memory of the true event. Important in a variety of aspects‚ these memory errors become especially crucial in terms of courtrooms and eyewitness testimony. Interestingly‚ 75% of false convictions are due to an eyewitness identifying the wrong person or misreporting how an event actually occurred. Witnesses aren’t intentionally

Fundamental Attribution Error (FAE) (Jones and Harris study 1967) The Fundamental Attribution Error (FAE) principle states that man tends to ignore outside pressure and factors when judging the behavior of others. This means that people believe that a certain action or behavior was a cause of an internal motive rather than some influence from external pressure. In simple words‚ the FAE describes the inability to step inside other people’s shoes. The name FAE was first coined by Ross in 1977

The main focus of this experiment was to find the relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the

ABSTRACT The Stroop experiment focuses on the interference of a person’s reaction time on a given task. Certain tasks can be performed with more accuracy due to the fact that our brain becomes conditioned to react automatically after exposure of the stimuli. In this particular experiment‚ eight-teen college students underwent the Stroop experiment in individualized laboratory rooms. Four students were male and fourteen were females. The experiment helped us examine the horse race model

Design of a Psychological Experiment Psyc 100 (0110-0129) Fall‚ 1996 Dr. Sternheim Report #1 (10 points) Problem: Suppose you are a psychologist who is interested in the effects of caffeine on the eye-hand coordination of students enrolled at UMCP. Design an experiment to test the hypothesis that caffeine enhances a student’s ability to hit a baseball. Describe your experiment by answering the following questions: 1) What are the independent and dependent variables? The independent variable

EXPERIMENT 5 TRANSVERSE STANDING WAVES A string attached to a turning fork is set vibrating at the same frequency as the tuning fork. The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY

RESULTS AND DISCUSSION The balanced equation of the reaction between sodium thiosulfate and Hydrochloric acid is: S2O32- (aq) + 2 H+ (aq) SO2 (g) + S (s) +H2O (l) Using beakers with the same diameter was very important in conducting the experiment. If different sizes were used‚ the visibility of the “x” on the paper beneath the beaker could disappear from view too early or too late than the hypothetical time depending on the depth of the solution. It was also significant to use the same timer
