Purpose: The purpose of this experiment is to apply Beer’s Law by analyzing samples provided by Q laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink. Procedure: To drop solutions into the test tubes and then determine the Beer’s Law relationship of

L. Casler The War on Drugs University of Southern California Introduction Nearly half a century has passed since Richard Nixon officially declared a War on Drugs. Several theories exist regarding Nixon’s motives behind the declaration. The most commonly cited theory states that the war on drugs was declared in response to the large number of soldiers returning home from the Vietnam War addicted to heroin. Proponents argue that Nixon actually declared a War on Drugs in fear of the civil rights

Environmental Science The Scientific Method Amber Steadham October 31‚ 2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical

Serina Harvell Mr. Colagross English 2 14 April 2014 The Drug Laws: A Time For Change The so-called "drug war"‚ and "drug laws" haven ’t seemed to be as effective as it was supposed to be. Its original intent was to attack the drug problem in America. President Richard Nixon started the war on drugs in the late sixties to stop drug abuse at the source‚ the distributors. Another intention of the drug laws was to show individuals that taking part in this illegal activity would cause serious consequences

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
