Conduct multiple trials Write down a procedure Identify the materials to be tested Record observations and data in a journal
I gave my students this multiple choice question: Alan is using cabbage juice to determine the relative pH of various household solutions. Which of these steps communicates the results of his investigation?

Only one answer is correct among these 4 choices:
- Conduct multiple trials
- Write down a procedure
- Identify the materials to be tested
- Record observations and data in a journal

Could you tell me which one is correct?
