coffee. The average pure caffeine yield was 0.330% with a standard deviation of 0.179. This yield is slightly higher than the yield of this report because of the error that occurred during the experiment. A small amount of coffee from the first extraction was stuck in the nozzle of the separatory funnel so it was removed with a pipet and then decanted. This resulted in a loss of product. The average impure caffeine yield was found to be .948% with a standard

The story The Structure of DNA: Cooperation and Competition demonstrates the nature of science in many ways. DNA was not discovered by just one person‚ it was discovered by many different scientist who built on each others’ ideas. The main scientists who were featured in the story were James Watson‚ Rosalind Franklin‚ Francis Crick‚ Raymond Gosling and Maurice Wilkins. In the case of this story‚ scientific knowledge assumes an order and consistency in natural systems. Science models were used

From a general standpoint the data collected matched the hypothesis formed‚ as the temperature increases the rate of respiration will increase as well. This was shown as the average ppm of oxygen was taken from each group. Comparing the data from the class is shows the effect of human error on the results. For example group #4 seemed to have back wards results this may
