Salinity Experiment Aim To determine a method of measuring a soil sample’s salinity level in order to measure 3 samples’ salinity level. Hypothesis I think that by running a current through a salt solution and measuring the resultant amperage‚ a pattern in the recordings will help find a soil sample’s salinity level. Variables Controlled Amount of solution (100 mL)‚ supplied voltage (4V)‚ amount of soil (50 gm) & water (150 mL) in soil sample’s solution. Independent Amps recorded

November 9‚ 2014 Madison Phillips Report Submitted: November 9‚ 2014 Title: Beers Law and Calorimetry 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

OCourtney Galfano English 1102 Holdway Obedience Stanely Milgram created an experiment involving Yale students to injure a third party using electric shocks and studied how many students would follow orders and go along with the experiment. The experiment consisted of two people‚ a leaner and a teacher. The teacher would be placed at a table containing many different buttons and switches that were labeled from slight shock to severe shock. Then the learner‚ who was an actor‚ was strapped

The Milgram experiment even though it was a hoax had a lasting effects on many of it’s participants in both positive and negative ways and is a example of why humans should not be used as test subjects. The Milgram experiment was conducted by Stanley Milgram a assistant professor of psychology at Yale. The experiment wanted to

considerable testing and consideration should be placed on aggregate type and size to ensure an adequate concrete mix. Two tests have been performed to establish the properties of the aggregates: 1. Compacted bulk density test 2. Sieve analysis II Testing For Compacted Bulk Density Objectives * To determine the specific bulk densities of a range of course‚ fine and mixed aggregates. * To determine the void content of the samples. * From this we can determine the optimum

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in

level. The objective of this experiment is to study the characteristic of four different types of membrane. The membranes used in this experiment are polyamide film ( AFC 99 ) as membrane one ‚ polyamide film ( AFC 40 ) as membrane two ‚ cellulose acetate (CA 202 ) as the third membrane and PVDF (FP 100 ) that act as the fourth membrane. In order to identify the characteristic of all four membranes‚ experimental procedures should be done. The variable for this experiment is the membrane maximum inlet
