point of water. I bet you didn’t know that! There’s a reason for that‚ but I’ll explain that a little later. First‚ let’s find out if salt can actually change the freezing and boiling point of water. To do so‚ we need to do an experiment. Now‚ if you’re going to do an experiment‚ you’re going to need a hypothesis. Let’s use mine. I said “if we know salt in the ocean’s water can affect its temperature‚ then I wondered if adding salt to regular tap water and bottled water would raise the water’s boiling

AIMS At the end of the experiment‚ students should be able to synthesise pure aspirin using chemical tests such as esterification and recrystallization independently and to also find out the melting point range of aspirin using melting point determination. INTRODUCTION Aspirin‚ which is also known as acetylsalicylic acid‚ is one of the commonly used and widely found in any drugstore or pharmacy. Its properties make aspirin a well-rounded drug that reduces inflammation and fever and also relieves

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

Yale University psychologist‚ Stanley Milgram‚ conducted an experiment in 1961 focusing on the conflict between obedience to authority and personal conscience. He examined justifications for acts of genocide offered by those accused at the World War II Nuremberg War Criminal trials. Their defense often was based on "obedience" - that they were just following orders from their superiors. Milgram’s experiment‚ which he told his participants was about learning‚ was to have participants (teacher) question

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

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

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

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
