What is the stick on the hotel bench for? It is for the convenience of the elderly who are feeling unwell. They can rest with the aid of a cane. The general process of inquiry begins with discovering and asking questions. After discovering the problem, you make assumptions about the answer to the question based on your existing knowledge and life experience. Design research plan, including material selection, design method steps, etc. Conduct research according to the research plan, obtain the results, and then analyze whether the results are consistent with the assumptions to draw conclusions. Not all questions can be answered in one go. Sometimes, wrong conclusions may be drawn due to imperfect methods of inquiry. Therefore, after drawing a conclusion, it is necessary to reflect on the entire inquiry process. The general method steps of inquiry experiments: ask questions, make hypotheses, formulate plans, implement plans, draw conclusions, express and communicate.

Commonly used methods in scientific inquiry include observation, experiment, survey and data analysis.

Observation is a basic method of scientific inquiry. Scientific observation can be done directly with the naked eye, or with the help of instruments such as magnifying glasses and microscopes, or by using tools such as cameras, video recorders, and video cameras. Sometimes measurements are also required. Scientific observation must have a clear purpose; the observation must be comprehensive, meticulous, realistic, and recorded in a timely manner; it must have a plan and be patient; it must think actively and record in a timely manner; it must exchange views and discuss. The design of the experimental plan should closely focus on the questions and hypotheses raised. When studying the impact of a condition on the research object, an experiment in which other conditions are the same except for this condition is called a controlled experiment. General steps: discover and ask questions; collect information related to the problem; make hypotheses; design experimental plans; implement experiments and record them; analyze experimental phenomena; draw conclusions. Investigation is one of the common methods of scientific inquiry. When conducting an investigation, you must first clarify the purpose and objects of the investigation, and formulate a reasonable investigation plan. During the investigation process, sometimes because the scope of the investigation is very large, it is necessary to select a part of the survey objects as samples. Keep truthful records during the investigation process. The results of the survey must be organized and analyzed, and sometimes mathematical methods must be used 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 check out books, periodicals and newspapers, visit relevant people, and search online. The form of data includes text, pictures, data, audio and video materials, etc. Organize and analyze the obtained information to find answers and clues
