Using the power of PASCO® technology, students first determine the activity of catalase by measuring the pressure change inside a flask containing hydrogen peroxide and a source of the catalase enzyme. Then they determine the effect of the change in pH on catalase activity. Complete instructions and data sheets are provided on the enclosed CD-ROM. This one-station kit contains sufficient materials for a single lab group of 4 students.
