Part 2: Do it faster! (15 min)

  1. Propose the question if there is something that can speed up or slow down a reaction from a state to a different state of material.
  2. See the video of what a catalyzer is and explain it with your words without forgetting to give examples.
  3. Analyze which materials can be a catalyzer and what are not. Present in the screen 5 materials that we can find in house, the students will vote if it is or isn’t a catalyzer.
