without causing harm to the specimen (2). Being classified as an indicator species‚ the Daphnia magna are extremely sensitive to changes to their marine environment‚ sometimes showing biological symptoms in response to toxicity exposure. (1). In this experiment‚ three Daphnia magna were treated with three different drugs to measure the change in their short-term cardiac function; ethanol‚ caffeine and nicotine. Ethanol‚ found in drinking alcohol is a

Breaching Experiment: The Human Response to the Invasion of Personal Space Have you ever been to a wedding and just felt completely confused because one of the female guests decided she was going to wear a wedding gown of her own to someone else ’s wedding? Wouldn ’t it be weird if one day‚ you walked into one of your discussion classes to find that your cool‚ hip‚ macho male T.A. just all of a sudden decided that to put on make-up‚ wear fake rubber breasts‚ and dress like a female to teach his

In August of 1971‚ Phillip Zimbardo constructed a mock correctional facility. Placing an ad in a local newspaper‚ and with over 70 responses‚ he conducted interviews with 70 male candidates across the U.S. and out of those 70 candidates 24 of them were sorted out through mental diseases‚ drug abuse‚ and psychological issues. With a pay of $15/a day‚ he divided the candidates‚ 9 guards and 9 prisoners. He constructed the basement floor at Stanford into a correctional facility taking the doors off

Prison Experiment Support Deprivation Theory Nick McCoy University of Iowa Philip G. Zimbardo in a pursuit to analyze the results of placing society accepted “good” people in an evil place constructed an experiment which represented a simulation of prison life. Ordinary middle class males were placed in a situation to monitor activities and behavior these males displayed when subject to the harsh environments of a prison. The results of the experiment were much more detrimental than expected

Distinctiveness between the right and left hemisphere of the brain Word Count: 995 Abstract The brain assymetry experiment is to investigate on the distinctiveness of the right and left hemisphere in the brain as each hemisphere has certain specializations. The experiment were carried out by initially asking the 25 participant on whether they were left or right handed and they had to choose the chimeric image which appeared younger to them. Laterality quotients were calculated in order to

Copper sulphate experiment Introduction There are a number of different methods of making salts‚ such as the reaction of a metal with an acid. Copper metal‚ however‚ does not react with sulphuric acid and so another method must be used. In this experiment a basic copper compound (copper(II) oxide) will be reacted with sulphuric acid giving copper(II) sulphate as one of the products. Method 1. Wear goggles and keep your face away from the beaker during the reaction 2. Place 20 cmm3 sulphuric

The Jewish Chronic Disease Hospital‚ The Tuskegee Syphilis experiments‚ and the Hepatitis studies at the Willowbrook State School‚ are a few examples of highly unethical research studies that have previously been conducted. Willowbrook State School may be one of the hardest to consider ethically‚ because it involved

The Cabbage Indicator Experiment My hypothesis for this experiment is if I put an acid or a base in to a neutral then it will change colors. My hypothesis was correct in assuming that it would change colors with different substances or mixtures. If I put an acid or a base in to a neutral then it will change colors. The red cabbage indicator did change colors. Greens for bases and reds and pinks for acids. An alternative hypothesis for this could be “If the red cabbage indicator is purple then adding

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
