First, pull out the adjusting shaft. The first gear is used to adjust the date calendar, and the second gear is used to adjust the time. Select the correct time zone and the area with good radio signal, and press and hold the button below the rotating shaft for 5 seconds to complete the automatic time adjustment. The general process of inquiry begins with finding and asking questions. After you find the question, make assumptions about the answer according to your existing knowledge and life experience. Design an inquiry scheme, including material selection, design methods and steps. According to the query scheme, get the result, and then analyze whether the result is consistent with the hypothesis, so as to draw a conclusion. Not all the questions can get the correct conclusion at once. Sometimes, due to imperfect investigation methods, 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 carried out 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; We should exchange views and have a discussion. The design of the experimental scheme should 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; The conclusion is that investigation is one of the common methods of scientific inquiry. In the process of investigation, 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 the survey, some interviewees should be selected as samples. In the process of investigation, it shall be recorded truthfully. The survey results should be sorted out and analyzed. Sometimes we should use mathematical methods to do 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 and newspapers, visit relevant people and surf the Internet. 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.
