Experiment 2: Experiment to investigate the effect of different concentrations of catalase enzyme on the breakdown of hydrogen peroxide

1. Propose an aim and hypothesis based on the theoretical context; when enzyme concentration increases, will rate of hydrogen peroxide decomposition increase? (AC 1.1)

2. Devise a methodology to investigate your hypothesis, identifying any risks and outlining steps taken to minimise risks (AC 1.2 and AC 1.3)

3. Carry out the proposed practical investigation (AC 1.3 and AC 1.4)

4. Record and present data in a format suitable for analysis and to verify or discredit the predictions made in the hypothesis (AC 2.1 and AC 2.2)

5. Evaluate the validity of your hypothesis (AC 2.3)

6. Review the practical investigation for any anomalies, errors or limitations linked to equipment or methodology and suggest proposed improvements (AC 3.1, AC 3.2, AC 3.3 and AC 3.4)

7. Ensure that the final lab report follows a format agreed with the tutor (AC 4.1)
