There only needs to be one report. I saw that you had it broken down into each experiment. I hope my comments hope to clarify that you only need one lab report. Remember you are focusing on experiment 3:What are the effects of pH on enzyme activity. The hypothesis for this experiment should be included in the introduction. Experiment 1 needs to be mentioned in the methods and results section because it was used as a baseline to set color intensity for experiment 3.
