Newton`s Second Law – Lab Report Name: Tasneen Ahsan Date: 19th November‚ 2012 Purpose To show how the acceleration of an object changes when‚ the mass changes and the net force is kept constant and when the mass is the same.. Hypothesis I predict that by changing the mass of the object will result in a change in the acceleration as Newton`s second law states that the magnitude of the acceleration of any object is directly proportional to the magnitude

each substance (Mbuthia‚ 2012). Results Test solutions that contained proteins reacted to the Biuret reagent by turning violet. Table 1 summarizes the test results. In summary‚ test solutions‚ including distilled water‚ as a control‚ starch‚ glucose‚ and soft drink did not contain proteins. Egg albumin was the only test solution that contained proteins.

Research Question How will the addition of different pH buffers to amylase affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine.
