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

Experiment 5 Polytropic Expansion of Air Object The object of this experiment is to find the relation between pressure and volume for the expansion of air in a pressure vessel – this expansion is a thermodynamic process. Introduction The expansion or compression of a gas can be described by the polytropic relation ‚ where p is pressure‚ v is specific volume‚ c is a constant and the exponent n depends on the thermodynamic process. In our experiment compressed air in a steel

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

media does not affect an audience. To support the hypothesis we will conduct an experiment using a sample group of Yr.11 students which attend Westminster school. Three different varied films will be shown for 3 minutes‚ Educating Rita‚ Braveheart and Bugsy Malone. During each film heart rates will be taken at the half-way point and the end to get qualitative results. The independent variable in this experiment is the actual violence viewed by the audience and the dependent variable is the heart

was going at a high speed when it reached the peak of its bounce it is hard to measure how high the ball had bounced on sight alone. Parallax errors were hard to avoid during this experiment as each bounce was a different height and the camera moved during filming. To improve the reliability of results the experiments could be filmed with high speed video camera which would capture more shots per second than an ordinary camera‚ allowing the footage to be analysed down to the most accurate shot taken

of this experiment was to figure out if the temperature of the reaction would rise‚ will the absorption rise as well. Reactions use energy‚ If there is energy than heat occurs. The Hypothesis that was figured out was‚ If the temperature rises‚ then the absorption will also go up. The Independent variable that was tested was temperature. The dependent variable that was being tested was color and absorption. The data was calculated by a spectrophotometer. The control group of this experiment was room

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
