GCSE SCIENCE COURSEWORK (BIOLOGY) PLANNING: Skill Area P Write down the aim of your Investigation. The aim of investigation is that to find out the optimum pH at which the enzyme catalase would best break down hydrogen peroxide. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). The purpose of the preliminary experiment was to find out the best source of catalase …showed first 75 words of 3512 total…

Moreover I will compare my results with those of my peers and also use results and findings of previous scientific research in this field of study to further verify my conclusions. Lastly, I intend to take the investigation one step further by not only identifying the optimum pH but also to study the pH itself.
