standardized tests? We designed an experiment which would put an answer to this question. The experiment tests the spectrum of standardized test scores of those who ate breakfast versus the scores of those who ate nothing. This experiment would be a single blind study because the scientists would not be biased therefore they would have no reason to alter the test results; it is a purely research type experiment. There would be two groups involved in the experiment- the experimental group‚ which would

The Effect of Animal Ownership on Stress The ability to deal with stress is important if only for health-related reasons. Stress causes many illnesses and complications. Individuals differ greatly in this respect. What they perceive as a source of stress and how they react to the intensity of it also seems to be an individual trait. Stressful life events can contribute to much higher utilization rates that intertwine with psychological distress (Rahe & Arthur‚ 1978). Physical and mental stress can

Caffeine effect on Daphnia’s heart rate Prepared for: Androniki Kloni By: Maria Mitsi October 6‚ 2013 Abstract Caffeine is a bitter‚ white crystalline xanthine alkaloid and a stimulant drug. Caffeine is found in varying quantities in the seeds‚ leaves‚ and fruit of some plants‚ where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants‚ as well as enhancing the reward memory of pollinators. An experiment was held‚ on an aquatic

Investigate the effect of on exercise on the heart rate. Aim: To find out if there is any relevant link between the amounts of exercise taken to increase a person heart rate. Equipment needed: Stop watch Screen volunteer P.E kit Calculator Record sheet Type of exercise: skip for few minutes ‚ then break in between and again repeat it once or twice. Method: First of all‚ we needed to take the resting heart rate of the person who is about to skip. Then‚ with the stopwatch one

What was the effect of photography on painting in the nineteenth century? The photograph was developed in 1839 simultaneously in England and France by Talbot and Daguerre. That is the technique of chemically fixing of an image produced by exposure to rays of sun. William Fox Talbot was an English scholar and scientist who developed the negative and positive process. He used sensitive paper soaked in sodium hyposulphite called calotype. This became the basis for all subsequent photography. Photography

The Stanford Prison Experiment was a very unique and brutal experiment. In 1973 the professor Philip G. Zimbardo set out to study how normal subjects such as college aged men would react as “prisoners” and “guards” in a mock prison setting. Stanford set up what they called a “mock prison” in the basement of Stanford University’s psychology building. During the experiment there were ten prisoners and eleven guards. The prisoners were stripped of their uniqueness by being dressed in matching smocks

Was the Milgram Experiment Ethical or Valid? In 1961‚ Stanley Milgram‚ a psychologist at Yale University‚ conducted an experiment on a group’s obedience to authority. This experiment has encountered intense scrutiny ever since its findings were first published in 1963; many people question the ethics and validity of the experiment. Multitudes of researchers have taken it upon themselves to determine the answers to the questions (McLeod). Based on new guidelines for ethics‚ Stanley Milgram’s experiment

Animal testing has been around since Aristotle’s time. Since then animal testing really took off for medical uses in the early 19th century. Since then laws have been put on animal testing when congress passed the Food‚ Drug‚ and Cosmetic Act in 1938. It is estimated that 26 million animals are abused in animal testing annually. Some of the causes include animal testing cannot stop or we would have no way of knowing if something is safe or not‚ assuming that animals and humans have the same DNA‚

"More than 100 million animals are poisoned‚ burned‚ crippled‚ and abused in other ways in U.S. labs each year."(#1video) Animal testing became a common method between 200-300 BC‚ these tests were often led by important male figures such as Aristotle. In 1242 Ibn al- Nafis used animals to test blood circulation‚ his theory of human blood circulation was later proven by William Henry many years later. In the 1660’s another scientist‚ Robert Boyle‚ theorized that living beings needed air to live‚

is essential for human survival and when this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution.
