HOOKE’S LAW EXPERIMENT Aim: The aim of this experiment is to determine the force constant (k) of the particular spring used. Introduction Hooke’s Law: Hooke’s Law is a law that shows the relationship between the forces applied to a spring and change in its length (extension). The relation is best explained by the equation: F= -k Δx F: Is force applied to the spring this can be either the strain or stress that acts upon the spring. k: Is the spring constant and details how hard

Effect of all-natural bath and body wash on millet seed growth. This experiment was conducted to determine what effect a household chemical would have on the growth of a plant. Everyday multitudes of chemicals are washed down the drains inside of our homes; many of these same chemicals are then being introduced into the environment through our water sources‚ such as rivers. This experiment will test the effect of all-natural bath and shower gel would have on the growth cycle of millet seeds. The

Abstract: Asch (1951) conformity experiment was conducted to investigate the extent of social pressure from a majority group on an individual. Asch conducted this study because he disagreed with Sherif’s (1935) conformity experiment‚ which had a small light in a dark room that did not move but he wanted to see how social pressure might affect a participant answer. Psychologist had earlier discovered that a small light in a dark room appeared to be moving‚ this was an illusion. Asch disagreed with

Title: Liquids and Solids Purpose: The experiment will help determine two important physical properties‚ boiling and melting point‚ of liquids and solids. Procedure: Before starting the experiment I gathered all materials appropriate for the experiment and prepare a safe environment for my experiment. I record the boiling point of the Isopropyl Alcohol and the melting point of powdered Acetamide with lab equipment such as the thermometer‚ capillary tube‚ beaker‚ test tube‚ and burner fuel

In 1970‚ in small town Riceville‚ Iowa‚ Mrs. Elliot decided to present an experiment she had started previously with a third grade class after the shooting of Martin Luther King Jr. Mrs. Elliot‚ had always presented the topic of racism in her classes‚ as she felt it was important for her students to truly understand what was occurring. The day after the wrongful killing of MLK Jr.‚ she said she wanted to start an experiment with her class because the predominant white male adult newscasters‚ spoke

atrocities against other women? The usual answer is to portray women guards as more like surrogate men (Sarah Helm). Dr. Herta Oberheuser was one of the most cruel‚ gruesome female doctors in Ravensbrück. Dr. Oberheuser ran many different types of experiments‚ but she had two certain ones she focused mainly on. She would test different types of injections on children‚ such as evipen and oil. After waiting until they either died‚ or still may be fully alive and aware she would continue working on them

Jacob Stewart Dr. Wells English 101 20 September 2013 In the 1950’s‚ a series of experiments were performed by psychologist Solomon Asch on the effects peer pressure can have on someone that would otherwise be stalwart in their judgment. In the experiment‚ a group of young men were shown a line with three other lines of various lengths next to it‚ and asked to determine which of three lines matched the length of the first line. There was‚ however‚ a catch: all but one of the men were

“polymer creatures‚” which are the things that are used in experiments about polymers. The polymer creatures‚ made out of two different polymers‚ are both hydrophobic and hydrophilic. This means that while the hydrophilic polymer absorbs water‚ the hydrophobic polymer keeps the shape that the creature was originally in while the water is inside the creature. Another name for this process is osmosis

Objective In this experiment the purpose is to study the period of the pendulum with different masses. Secondly to also study the relationship in the different lengths of the string and how it affects the period. Thirdly to find the different (time) periods in the changes in the arc size. Theory If the pendulum is set ‚ the force of the motion is used to swing back and forth . where the t period is the time the pendulum takes to complete a cycle of oscillation. As t-1/f the complete distance of
