Hypothesis: If I pluck the sixth string of the guitar from frets nine- twelve‚ then those frets will not produce harmonics that are able to be heard clearly. Materials: Acoustic guitar ( adult or child sized) Cloth tape measure‚ metric Lab Notebook Procedures on finding harmonics on your guitar: 1.Select a string and starting at the twelfth fret‚ try to play a harmonic in that fret by lightly damping the string above the twelfth fret. a.If a harmonic is heard (and you hear a ringing

Daphnia Experiment Report 1. Introduction Caffeine is found in many plant species‚ where it acts as a natural pesticide. It is found most commonly in cocoa‚ tea and coffee‚ but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans‚ caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure‚ restlessness‚ insomnia and anxiety which‚ in

prison make the inner demon come out in the prisoner/guard or is the prisoner /guard already wired that way? The Stanford Prison Experiment was a study of the psychological effects of becoming a prisoner or prison guard. This experiment was led by a psychology professor named Philip Zimbardo‚ he had the help of a team of researchers. The purpose of this particular experiment was to induce disorientation‚ depersonalization‚ and DE individualization in the participants. After a period of time behind bars

Abstract: Asch (1951) conformity experiment was conducted to investigate the extent of social pressure from a majority group on an individual. Asch conducted this study because he disagreed with Sherif’s (1935) conformity experiment‚ which had a small light in a dark room that did not move but he wanted to see how social pressure might affect a participant answer. Psychologist had earlier discovered that a small light in a dark room appeared to be moving‚ this was an illusion. Asch disagreed with

The experiment was divided into three days to test the detoxification activity of Beetles grown on Mung and Black-eyed peas. In day 1 of part I‚ four beetles per group were chosen from each food sources for both ANAE and BNAE activity. In part I‚ the crude extract was obtained by the experimental design outlined in the lab manual (Course Supplement for Bio 101‚ p.68). Each member of the group took care of one Bean beetle crude extract. First‚ the sex was identified by the following instructions of

An experiment by FACUNDO LOPEZ MENTOS GEYSER CARBONATED DRINKS AND MENTOS PROBLEM STATEMENT: WHAT IS THE EFFECT OF MENTOS ON CARBONATED DRINKS? BACKGROUND INFORMATION: The soda contain sweeteners (sugar or artificial sweeteners) flavoring‚ water and preservatives. Carbon dioxide (CO2) gas is added to the soda trough a high pressure process that causes the gas to dissolve into the liquid‚ when the soda is opened the gas is relieved

Boyle’s Law Experiment Aim To show that Pressure is proportional to the inverse to volume Method A gas syringe was attached to a pressure sensor. The pressure sensor was calibrated‚ assuming the atmospheric pressure at the time of the experiment was 100kPa. Differing volumes of gas were created in the gas syringe and they were recorded as were the corresponding values of pressure at that particular volume. The volume was varied between 20cm3 and 75cm3. Results A set of readings was obtained

Abstract:Conjugation is a natural occurring process that involves the transfer of DNA from one cell into another through a physical connection between the cells. In the following experiment‚ two strains of Escherichia coli bacterial cells (donor F’lac+strs and recipient F-lac-strr) underwent conjugation to produce a transconjugant strain (F’lac+strr). MAC plates and streptomycin were utilized to determine if conjugation had occurred. When plated‚ the donor colonies appeared red and the recipient

AIM: To carry out a lab experiment to decompose a carbonate using heat‚ also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say‚ the more active the metal‚ the more stable is the carbonate. Thus‚ the carbonates of sodium and potassium are stable at the highest temperature
