Experiment is one of the basic methods of scientific research. According to the purpose of scientific research, we should try our best to exclude the external influence, highlight the main factors, and use some special instruments and equipment to artificially change, control or simulate the research object, so as to make something (or process) happen or reappear, so as to understand natural phenomena, natural attributes and natural laws.
Experiments are different from experiments. Experiment is a clear, concrete, operable, data-based, algorithmic and responsible technical operation for solving cultural, political, economic, social and natural problems and testing a new hypothesis, hypothesis, principle and theory or verifying an existing hypothesis, hypothesis, principle and theory in corresponding scientific research.
Scientific experiment refers to the social practice form of observing and studying natural phenomena and their regularity under the condition of manual control by using certain instruments, equipment and other material means according to certain purposes. It is an important way to obtain empirical facts and test the authenticity of scientific hypotheses and theories.
It includes not only instruments, equipment and experimental objects, but also related social factors such as background knowledge, theoretical assumptions, data analysis, scientific explanation, negotiation, exchange and fund acquisition among experimenters. Its nature is not only material, but also cultural and social.
Experimental steps:
1, observation is a detailed record of facts and events.
2. There are clear procedures to define this problem.
3. Proposing a hypothesis is a temporary explanation of a matter or a relationship.
4. Collect evidence and test hypotheses. On the one hand, we should be able to provide objective conditions for hypotheses; on the other hand, we should find ways to measure relevant parameters.
5. Publish research results: Scientific information must be open and transparent, and the real scientific concern is to solve problems.
6. Architectural theory. Isolated problems cannot be theorized, and scientific theories can be falsified.
