Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

Seth Dennison and Jenna Snyder John Bryan Psychology of Gender 104 10/31/2012 Psychological Gender Experiment For our psychological gender experiment we chose to focus on the topic of memory differences between genders. At first we wanted to figure out if one gender had a better memory than the other‚ but then we also wanted to observe whether or not their memory showed better results when the objects were related to their gender. Therefore‚ the hypothesis we constructed was: If

Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the

The Atrocities and Liberation of Concentration Camps If you combine sadistic Nazi soldiers‚ a "license to kill‚" and twenty-six million people whom they took their aggression out on‚ you have the Holocaust. From torture to murder‚ the concentration camp prisoners experienced almost every despicably‚ inhumane act one can imagine. Hitler ’s Nazis will never be able to justify this ultimate example of cruelty and unfairness. Although the Holocaust occurred nearly seventy years

The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

Duracell‚ Energizer‚ Eveready and Rayovac? Hypothesis We think that Duracell will last the longest because their advertising claims that no other battery "beats the copper top." Materials 1. Four of the same type‚ size and brand flashlights. 2. Two D-size batteries from each of the following brands: * Duracell * Energizer * Eveready * Rayovac 3. Two other D-size batteries to test each flashlight and bulb before starting tests. Procedure We tested each

- Quasi Experimental Design: If the researcher lacks control over the assignment of participants to conditions and does not manipulate the causal variable of interest‚ the design is quasi experimental. o Quasi Experiments do not have internal validity because participants are not randomly assigned to conditions and the researcher may have no control over the independent variable. - Basic Confounds in Quasi Experimental Design are : o History o Maturation (Emotional‚ Physical & Psychological)

The Milgram Experiment Stanley Milgram‚ a famous social psychologist‚ and student of Solomon Asch‚ conducted a controversial experiment in 1961‚ investigating obedience to authority (1974). The experiment was held to see if a subject would do something an authority figure tells them‚ even if it conflicts with their personal beliefs and morals. He even once said‚ "The social psychology of this century reveals a major lesson: often it is not so much the kind of person a man is as the kind of situation

The Milgram experiment The Milgram experiment came about by a Yale University psychologist by the name of Stanley Milgram. The experiment was to test how well the study participants were and the willingness of study participants to obey an authority figure who instructed them to perform acts that conflicted with what they thought was right. He concluded people obey either out of fear or out of a desire to appear cooperative even when acting against their own better judgment and desires. Stanley
