The Experiment Gloria Isham Central Texas College Twenty- six men are chosen to participate in the roles of guards and prisoners in a psychological study led by a Doctor Archaleta for which each participant is to receive $14‚000 after two weeks. Travis has just lost his part time job and is a peace protester who wants to travel to India with his girlfriend. Barris is a 42-year-old who lives alone with a domineering mother‚ who has made him join the experiment to raise money for her hip operation

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Design of a Psychological Experiment Psyc 100 (0110-0129) Fall‚ 1996 Dr. Sternheim Report #1 (10 points) Problem: Suppose you are a psychologist who is interested in the effects of caffeine on the eye-hand coordination of students enrolled at UMCP. Design an experiment to test the hypothesis that caffeine enhances a student’s ability to hit a baseball. Describe your experiment by answering the following questions: 1) What are the independent and dependent variables? The independent variable

Caffeine plays a big role in todays society. Caffeine is found in some beverages such as coffee and tea (Sciencedaily.com). Americans consume 400 million cups of coffee per day‚ equivalent to 146 billion cups of coffee per year (The Huffington Post‚ 2011). This made the United States the leading consumer of coffee in the world (The Huffington Post‚ 2011). People never realize the effect caffeine can have on their body. Caffeine could be a reason why you become dehydrated. Can caffeine cause dehydration

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

stay up all night rewriting it. When 7 am rolls around‚ you’re exhausted and ready to sleep. There’s one thing that can keep you awake‚ caffeine! You buy a monster or an iced coffee and drink it during lunch. A teacher approaches and demands you throw your drink in the trash. You have no energy for the rest of the day‚ resulting in failing all your assignments. Caffeine should be allowed to have more energy‚ to help kids with headaches or other issues‚ and because they taste good and make kids happy

those that didn’t know this‚ caffeine is a drug. B. Statistics have proven that any amount exceeding “five or more cups of coffee will increase the risk of cardiac arrest (Caffeine).” “60 percent of the total caffeine consumed in the United States is from coffee as well as 16 percent comes from soft drinks and teas (Caffeine).” Many children and adults consume coffee on the daily and they do so to get energy into their body. “The average daily consumption of caffeine for adults in the United States
