The rate of activity of an enzyme.
Write a report about the catalaze experiment:
- Get a tall 250 cm3 beaker
- Add 5 cm3 of dishsoap with a 10 cm3 syringe
- Add 7 cm3 of 3% hydrogen peroxide with a 10 cm3 measuring cylinder and gently swirl the two liquids without generating bubbles
- Stir the 5% yeast solution and add 15 cm3 with a 50 cm3 measuring cylinder to the beaker
- Let the reaction occur for 2 minutes
- Measure the foam’s height with a ruler
- Discard the reaction in the sink
- Repeat the reaction and the measurement adding 10 cm3 of 3% hydrogen peroxide instead of 7 cm3
This must be the structure of the report:
1. Title
2. Research Question
3. Background Information (remember to add in-text citations!)
4. Hypothesis
5. Variables (independent, dependent and controlled)
6. Materials (add size, units and uncertainties)
7. Method
8. Safety, Environmental and Ethical issues
