Introduction Milgram Experiment Method 40 men were recruited for a lab experiment investigating “learning”. In exchange for their participation‚ each person was paid $4.50. After the WWII‚ Stanley Milgram a psychologist of Yale University posed a question‚ “Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices? These men were introduced to another participant who were actually actors. These men were given role

How did your proposed procedures or flow charts at the beginning of this experiment compare to the actual procedures of this lab exercise? I had to change the process I did things a little to allow adequate time for the sand and the benzoic acid crystals to dry on the paper towels‚ and for the water in the paper cup to evaporate from the salt. 2.

OBJECTIVES To demonstrate the effects that a bypass capacitor has on amplifier voltage gain (Av). To demonstrate the ac operation of the common-emitter (CE) amplifier. INTRODUCTION A common emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies‚ typically used as a voltage amplifier. In this circuit the base terminal of the transistor serves as the input‚ the collector is the output‚ and the emitter is common to both. The input signal to a

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

First‚ the buffer was prepared by using the formula as follows: Figure 1: Calculation for prepare 0.1 M potassium phosphate buffer at pH 6 3.4007g of potassium phosphate was weighed and placed in 300 mL beaker. Then‚ 125 mL of water was added into the beaker that contained potassium phosphate. The mixture was dissolved using the stirring rod‚ and then the magnetic stirring bar was placed in the beaker for further dissolve when measuring the pH. The pH meter was used to measure the solution

Investigation: The Stanford prison experiment was originally intended to run for a fortnight. However it lasted only 6 days and was ended earlier than initially planned due to the terrible living conditions and psychological problems that developed as the ‘inmates’ and ‘guards’ interacted.. The experiment was run by Philip Zimbardo‚ Craig Haney‚ David Jaffe‚ and W. Curtis Banks. The test subjects were young male college students that were chosen from 75 volunteers. The volunteers had replied to

Spirit Burner Experiment Aim: To perform an experiment in the labs to determine the heats of combustion of selected alcohols and then to use this information and the gathered data from chemical data sources to determine trends in the longer chain alcohols. The Variables that MUST be controlled throughout the experiment are: • The height from spirit burner nozzle to the base of the water filled beaker • Air drafts around the room must be kept to minimum so as to keep the heat on the base of the
