Part 2: Do it faster! (15
min)
- 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.
- See the video of what a catalyzer is and explain it with your words
without forgetting to give examples.
- 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.
