The Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific

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

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

The purpose of this experiment was to determine if cars on Woody Hayes Drive needed additional traffic control to reduce speeding.

Introduction The brain is one of the most complex machines to ever exist. Many experiments are conducted to try to learn more about the brain. Within the Bransford & Johnson experiment‚ their experiment focusing on the memory aspect of the brain. They focus on schema theory which was proposed by J. Piaget. Schema is the mental framework that helps interpret information by comparing new information to pre-existing knowledge. This study was conducted in 1972 by Bransford and Johnson. The aim of

ABSTRACT The study us experimenters re-conducted was based on Norman Triplett’s study of social facilitation and how social presence or encouragement improves an individual’s speed and consistency in their performance. The experiment was replicated in using several trials for accurate results and was split into two stages: a mental challenge and a physical challenge. The two male and two female participants ranged from ages 15 to 17 years old. For the mental challenge‚ each participant was pulled

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
