Experiment 7 General Safety Considerations 1. 1-Butanol and 1-bromobutane are toxic and irritating. Avoid all contact by constantly wearing goggles‚ gloves and working in the hood. Neither of these compounds can be poured down the drain. Like all products‚ 1-bromobutane should be turned in to your TA in a labeled vial. Any excess butanol should be discarded in non-halogenated waste. 2. H2SO4 is extremely corrosive. In very diluted form it can be poured down the drain‚ all other precautions

Introduction The common bean (Phaseolus vulgaris) is a fast growing plant and is used commonly in experiments due to its easy testability. It can grow in a variety of conditions and is easy to see the effects of different treatments. The idea of the treatment that we applied to our bean plants came from our class and scientific papers that help back our experiment. Examining many studies on the effects of nitrogen fertilizer on a variety of plants helped us better understand what the fertilizer was

Behavioural Study of Obedience: Milgram’s Experiment M.J George Brown College #1) Obedience I think the three aspects of the situation faced by the subjects in Milgram’s study were the prestige of the university‚ the proximity of the experimenter‚ and the money paid. These aspects were the most influential in causing the subjects to obey. The influence of the prestige of Yale University was a key point to get the obedience of the subjects. People are prone to obey more

* Laser (Monochromatic light) * Rectangular Perspex * Ruler * Pencil * Paper * Protractor * Calculator Method: 1. Place your Perspex in the middle of a piece of paper. 2. Use a sharp pencil to draw its outline. 3. Remove the Perspex from the paper. 4. Use a protractor to draw the line that is normal from the long end of the rectangle. 5. Turn the laser on. Place the laser on the paper so that the laser line is projected onto the normal line and intersects

Purpose The purpose of this experiment was to show teachers whether or not they should allow their students to chew gum in class. If teachers take a gander at this experiment then teachers may allow gum for the chance of better test grades. It may also help individuals‚ knowing that chewing gum can improve concentration on short term auditory memory tasks. Materials and Procedures Chewing gum Audio Memory tasks Pencil Paper Participants consent form Procedures 1. Have 3 packs each of these gum

Stanford Prison Experiment Following the American Psychological Associations guidelines Zachary Hudson Waterford District High School Abstract The Stanford prison experiment‚ an unethical experiment created to study human nature in the most hellish of environments. Regular students were deceived into applying for the experiment itself and later regretted the choice because of the events that occurred during the short time that experiment ran in. The experiment ran and quickly

Introduction: The purpose of the plant growth experiment was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant. The plants we were testing were radishes We decided on testing the validity of Miracle Grow with radishes to determine if fertilizers are worth purchasing. Hypothesis: If the recommended amount
