- Write the experimental procedure like a step-by-step recipe for your science experiment. A good procedure is so detailed and complete that it lets someone else duplicate your experiment exactly!
- Repeating a science experiment is an important step to verify that your results are consistent and not just an accident.
- For a typical experiment, you should plan to repeat it at least three times (more is better).
- If you are doing something like growing plants, then you should do the experiment on at least three plants in separate pots (that’s the same as doing the experiment three times).
- If you are doing an experiment that involves testing or surveying different groups, you won’t need to repeat the experiment three times, but you will need to test or survey a sufficient number of participants to insure that your results are reliable. You will almost always need many more than three participants!
