  1. Activity: Using an inorganic catalyst • Pour some hydrogen peroxide into a test tube. • Note the bubbles. The hydrogen peroxide breaks down naturally but very slowly. • Add a spatula of manganese oxide, an inorganic catalyst. What happens? • What has happened to the hydrogen peroxide? • What has happened to the manganese oxide?

  2. Activity • Add a spatula full of yeast to a test tube. • Pour some hydrogen peroxide over the yeast. • How does this reaction compare to the one with manganese oxide.? • What happens to the yeast?
