The Jewish Chronic Disease Hospital‚ The Tuskegee Syphilis experiments‚ and the Hepatitis studies at the Willowbrook State School‚ are a few examples of highly unethical research studies that have previously been conducted. Willowbrook State School may be one of the hardest to consider ethically‚ because it involved

Olive and Barbier report on research conducted in Université de Poitiers‚ in France. The goal of their experiment was to compare the time and cognitive effort it takes for students to take notes when the information is in a paragraph verses when the information is formatted into bullet points. To compare this‚ the participants were split into groups. One group took notes from a text formatted into bullet points‚ the other took notes from a paragraph. The participates each took notes from their respective

Sulfa Drugs: Preparation of Sulfanilamide Introduction The purpose of this experiment is to prepare sulfanilamide from p-Acetamidobenzenesulfonyl chloride. This will be done using reflux‚ vacuum filtration‚ and melting point determination. Experiment Scheme6 Figure 1. Reaction equation.6 A hot water bath was prepared in a fume hood using a 250-mL beaker. 2.5 g of p-acetamidobenzenesulfonyl chloride was placed into a 50 mL Erlenmeyer flask and 11 mL of dilute ammonium hydroxide solution

Distinctiveness between the right and left hemisphere of the brain Word Count: 995 Abstract The brain assymetry experiment is to investigate on the distinctiveness of the right and left hemisphere in the brain as each hemisphere has certain specializations. The experiment were carried out by initially asking the 25 participant on whether they were left or right handed and they had to choose the chimeric image which appeared younger to them. Laterality quotients were calculated in order to

without causing harm to the specimen (2). Being classified as an indicator species‚ the Daphnia magna are extremely sensitive to changes to their marine environment‚ sometimes showing biological symptoms in response to toxicity exposure.

Introduction: The marshmallow experiment is one of the best-known studies in psychology that was conducted in the late 1960’s by an Australian-born clinical psychologist Walter Mischel at Stanford University. Back then‚ the study tested over 600 nursery kids and this experiment has been existing and continuously conducted by researchers until now. The instruction was that the children could eat one marshmallow immediately or if they could wait they would receive two marshmallows later. The purpose

In 1971‚ The Stanford Prision Experiment was performed in order to see behind two contrasting behaviors that humans can show in a power driven institution. The point was to understand aggressive behavior typically shown by guards or people in the position of power using it to hold reign over the prisoners who in turn respond with submissiveness‚ and see how this relates in real world situations. Achievement of conclusion was the information gathered by the role play of students in an exercise of

turning into accidents. When the snow melts the road salt gets dissolved into the melted ice and snow and becomes a formula. This formula sinks into the land (soil mostly) and kills vegetation. The purpose for this exit project experiment is to find out what are the affects of road salt on plants. The reason for doing this lab is to find out what a certain concentration of road salt will have an affect on a specific type of plant. Also to see what changes will occur like the color
