The general process of inquiry begins with finding and asking questions. After finding the question, make assumptions about the answer to the question according to your existing knowledge and life experience. Design investigation 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, because the method of inquiry is not perfect, wrong conclusions may be drawn. Therefore, after drawing a conclusion, we should reflect on the whole inquiry process. The general methods and steps of inquiry experiment are: asking questions, making assumptions, making plans, implementing plans, drawing conclusions, expressing and communicating.

The common methods of scientific inquiry are observation, experiment, investigation and data analysis.

Observation is the basic method of scientific inquiry. Scientific observation can be made directly with the naked eye, with the help of magnifying glasses, microscopes and other instruments, as well as cameras, video recorders, video cameras and other tools, and sometimes measurement is needed. Scientific observation should have a clear purpose; Observation should be comprehensive, meticulous and realistic, and recorded in time; Planned and patient; Think positively and record in time; It is necessary to exchange views and discuss. The design of the experimental scheme should closely focus on the questions and assumptions raised. When studying the influence of a condition on the research object, experiments with the same conditions except this condition are called control experiments. General steps: find problems 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. Investigation is one of the common methods of scientific inquiry. When investigating, we must first make clear the purpose and object of the investigation and make a reasonable investigation plan. Sometimes, due to the large scope of investigation, we must select some objects as samples during the investigation. In the process of investigation, we must record it truthfully. We must sort out and analyze the survey results. Sometimes it is necessary to use mathematical methods for statistics. Collecting and analyzing data is also one of the common methods of scientific inquiry. There are many ways to collect data. Go to the library to consult books, newspapers and periodicals, visit relevant people and collect them online. The forms of data include words, pictures, data, audio-visual materials, etc. It is necessary to sort out and analyze the obtained data and find the answer.
