HYPOTHESIS - 1923 Haldane & Oparin propose hypothesis that life originated as simple molecules followed by cells - conduct simple experiments that show that organic compounds can form cell-like structures 3. EXPERIMENTATION - 1953 Urey and Miller collaborate effectively to design an experiment/model to simulate conditions on early Earth and test the hypothesis that life molecules could originate on Earth 4. RESULTS - Urey and Miller results confirm that simple

Investigation: The 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. The volunteers had replied to

Conclusion The purpose of our experiment was to determine if reading off words in various colors helped improve memory. Our hypothesis was that color helped memory and it was in fact proven by our experiments. According to data table 2‚ the average words remembered by the white control group was 6.4‚ while the other groups with the colors had averages of 6.8 and 8.2. Our hypothesis also proven in table 3‚ where the average words remembered by the control was 4.6 and the other two groups had averages

In the Milgram experiment‚ a man picks random people to participate in an experiment. They believe that they are helping discover the roles of punishment on behavior. Although‚ this is not true.

In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable amino acids called polypeptides. The aim of this experiment is to investigate the effect of changing temperature on the activity of enzymes. After experimentation the optimum temperature for enzyme activity will be established and the effects

Title Experiment with a spiral spring (Oscillation) Objective 1. To show how the time of vertical oscillation depends on the load 2. To determine the spring constant 3. To determine the effective mass of the spring Introduction In this experiment‚ it is to show how the time of vertical oscillation depends on the load‚ to determine the spring constant and to determine the effective mass of the spring. An ideal spring is remarkable in the sense that
