Bubble Trouble - GCSE Coursework Raj Patel Introduction The problem posed is how to speed up the reaction of hydrogen peroxide to water and oxygen using the enzyme catalase. The catalase will be the independent variable in the experiment, and the amount of oxygen produced is the dependent variable. Using 5 different concentrations of the enzyme for the experiment we aim to measure progress by how big the foam column is to see how much oxygen is produced. I am going to vary the catalase and in order for a fair test I will keep the others constant. Hydrogen Peroxide ---...Catalase...---> Water and Oxygen Apparatus Test tube Water Bath Timer Planning the investigation I will vary the catalase in this experiment. This will be my independent variable. The dependant variables (e.g. height of foam) cannot be changed to keep this a fair test. I predict that the more catalase added to the hydrogen peroxide, the more oxygen will be produced...
