    Stanford prison experiment was originally intended to run for a fortnight. However it lasted only 6 days and was ended earlier than initially planned due to the terrible living conditions and psychological problems that developed as the ‘inmates’ and ‘guards’ interacted.. The experiment was run by Philip Zimbardo‚ Craig Haney‚ David Jaffe‚ and W. Curtis Banks. The test subjects were young male college students that were chosen from 75 volunteers.

    to certain scientific experiments‚ thought experiments also involve objects that are not found anywhere in nature. As mentioned earlier in this paper‚ genetically identical mice‚ which were used in an experiment to test whether or not a certain chemical caused lung cancer‚ are not found anywhere in nature — the genetically identical mice are a product of science. In this example‚ the elements of the experiment (the mice) were unnatural‚ yet the conclusion of the experiment yielded significant‚ real-world

    Ashley Perez Biology 124 September 15‚ 2013 Discussion Paper In the experiment of Mr. Miller‚ I understand that he sealed in certain elements that stimulated the conditions that he thought were presented in the beginning of earth’s time and tested the chemicals that would be there a few days later. Miller predicted that prehistoric earth had certain chemical reactions that made organic compounds from inorganic base. The experiment used water‚ methane‚ ammonia‚ and hydrogen. The chemicals were

    so the skeletal muscle cells are supplied with more oxygen and respiratory substrates used to generate energy in respiration where it is needed. A drug that increases heart rate is called a positive chronotrope‚ and this is demonstrated in this experiment when adrenaline is used to increase heart rate in Daphnia. One of the ways adrenaline increases heart rate is through the action of what is known as a ’second messenger ’ or ’transduction component ’‚ in this case it is a chemical made in the

    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

    dominant thumb experiment is used to observe the correlation between handedness and thumb dominance and whether one inherited trait will always influences another correlated trait. Examples of this experiment of this can be traced back as far as 1908. In this experiment 50 people were asked to clasp their hands and the thumb dominance. Once the hands were clasped‚ one thumb would naturally overlap the other and the handedness of each subject was noted. The hypothesis of the experiment is that when

    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
