The general process of inquiry begins with finding and asking questions. After I found the question, I assumed the answer to the question according to my existing knowledge and life experience. Design inquiry scheme, including selection of materials, design methods and steps, etc. I make an inquiry according to the inquiry scheme, get the result, and then analyze whether the result is consistent with the hypothesis, so as to draw a conclusion. Not all questions need to be explored once to get a correct conclusion. Sometimes, due to the imperfect methods of inquiry, wrong conclusions may be drawn. Therefore, after the conclusion, it is necessary to reflect on the whole inquiry process.

General steps: find and ask questions; Collect information related to the problem; Make assumptions; Design the experimental scheme; Conduct experiments and record them; Analyze experimental phenomena; Draw a conclusion.

Sometimes, due to the large scope of investigation, we must select some objects as samples during the investigation. We must record it truthfully during the investigation.
