实验原理英文Experiments are conducted to investigate, validate, or demonstrate a specific scientific or theoretical principle. The underlying principles behind an experiment can vary greatly depending on the field of study and the specific research question being addressed. Below are some general principles commonly followed in scientific experiments:1. Hypothesis: Experiments often start with a hypothesis, which isa tentative explanation for a phenomenon or a prediction about the relationship between variables. The hypothesis guides the experiment design and the collection of data.2. Independent and dependent variables: Experiments typically involve manipulating one or more independent variables, which are factors that can be changed or controlled by the researcher. The effect of these variables on the dependent variable, which is the outcome or response being measured, is observed and analyzed.3. Control group and treatment group: To assess the effect of the independent variable, experiments often have a control group that receives no treatment or a placebo. The treatment group receives the manipulated independent variable. By comparing the results of the treatment group with the control group, researchers can determine the causal relationship between the independent variable and the dependent variable.4. Randomization: Random assignment of subjects or samples to treatment and control groups helps minimize bias and account for individual differences. This ensures that any observed effects aremore likely due to the independent variable and not other external factors.5. Replication: Conducting experiments multiple times with different subjects or samples allows researchers to verify the consistency and generalizability of their findings.6. Data collection and analysis: Experiments involve collecting data through various methods, such as surveys, observations, or measurements. Statistical analysis is then performed to determine if the results support or reject the hypothesis.7. Control of variables: Experiments strive to control or account for all variables other than the independent variable that could influence the dependent variable. This control helps ensure that any observed effects are indeed caused by the manipulated independent variable.By following these principles, experiments provide a systematic way to test hypotheses, uncover new knowledge, and contribute to the advancement of scientific understanding in various fields.。

Unit 10 Scientific Attitudes Text A Science had its beginning when man started asking questions about his env ironment. He wondered where the sun went at night and why the sky was blue. He questioned why the wind blew and the leaves fell. He sought answers to these and other questions. Not all his answers were correct, but at least he did want to know.Curiosity and ImaginationScience began to develop rapidly when man laid aside his wrong beliefs and began to seek true explanations. Y oung children are curious about how things work. The child wants to take apart a watch to see what makes it work.Benjamin Franklin wondered about lightning. He combined his curiosity with imagination and carried out his well-known experiment to show that lightning and an electric spark are the sam e thing. Curiosity and imagination are important qualities which help stimulate the discovery of new facts and advance science.Belief in Cause and EffectScientifically minded people believe in a “cause-and-effect’’relationship. They feel there is a perfectly explanation for everything. For example, there is a good reason why some leaves turn red and others yellow in the fall. Changes such as these, which are easily observed, are called phenomena. Some common phenomena, however, are not completely understood. Still others cannot be explained at all at this time. In cases where the explanation is unknown the scientific point of view is that there is a reason if it can only be discovered.Being Open-MindedOpen-mindedness is also ex tremely important to a scientific attitude. This means the ability to face the facts as they are regardless of what one has previously thought. It includes an ability to accept new and sometimes even disagreeable ideas. The worker in science must face facts whether they are pleasant or unpleasant. He must expect many failures and be willing to try again. Thomas Edison failed thousands of times before he succeeded in producing the first electric lamp.The solutions to real problems cannot be seen in advance. Scientists must be able to change their thinking and to adapt their theories to new facts as they are discovered. The mind cannot be made up once and for all. New knowledge may make a change in thinking necessary. This is another way of saying that man’s understanding is always less than perfect. What is accepted as true often is relatively, and not absolutely, true. A scientific truth offers an explanation that is acceptable only in the light of what is known at a particular time.Respect for the view s of othersAnother part of a scientific attitude is respect for the views of others. This is easy when these views are like one’s own. The difficulty comes up when their ideas are different. V iews which are entirely new or foreign may also be hard to accept.New ideas are frequently very slow to be accepted. Scientists such as Galileo, Louis Pasteur, and Edward jenner were laughed at because they held theories that were not accepted. Respect for new ideas is important for continued progress in all fields of knowledge.Opinions Based on EvidenceSometimes evidence is not complete. It may take time for new facts to become available. When they are available, a person may have to change his mind. New findings may also require a “wait-and-see’’ attitude. For example, there is an experiment on the sprouting of seeds which has been running for more than 50 years. The purpose is to determine how long a time seeds can be buriedin the ground and still grow when proper conditions for growth exist. (596 words) (12) (30) Text BSolving problems ScientificallyThere are scientific ways in which man solves problems. Once his curiosity has been aroused, he uses certain methods and procedures to obtain new knowledge and greater understanding. Although the methods are not always the same, there are usually certain elements in the procedures that are similar.Recognizing the problem Problems must first of all be recognized. The right answers can be obtained only if the right questions are asked. A thoroughly understood problem is well started toward solution. Problems arise in a variety of ways. Sometimes they grow out of a chance observation. They may result from reading, from laboratory experiments, or simply from thinking. They also may result from new developments or from new or different human needs. T oday, for example, problems are arising from new discoveries in the fields of nuclear physics, biological engineering and microelectronics. The development of industry has also brought about large numbers. Of problems which have to be solved.Collecting Information Next, the scientist tries to learn as much as possible about it. Often this means going to the library and studying books whi ch contain accounts of man’s experience and knowledge of the problem. This is called searching the literatureThe scientist may find that others have already solved all or a part of the problem. Occasionally he finds answers to closely related questions, which give clues for solving the new one. In his search the scientist accumulates much background information. With these new ideas and facts he builds a firm foundation for solving the problem.. Organizing the Information After the scientist has finished this part of his work he will probably take the many facts which he has collected and organize them into some kind of system. This may be a logical classification or it may be a mathematical analysis. Usually the analysis will show unanswered questions. Sometimes it will suggest areas that are in need of further study. Perhaps one of the most important results of such an analysis is that it indicates certain truths, which generally are called inferences.Making a Hypothesis In making an inference the scientist has built up a hypothesis. A hypothesis is only a “best’’guess. It must next be tested.If it is correct, then certain things should follow. This means if a particular ex periment is carried out, certain observations ought to be possible or it should out, certain observations ought to be possible or it should be possible to make certain predictions.Should the observations or predictions turn out to be as expected, the scientist has added confidence in the probable truth of his hypothesis. If, however, observations cannot be made or the predictions are unreliable, then the hypothesis will probably be given up or at least modified.The Experiment The hypothesis must check with the facts. Scientific facts are usually established by work in the laboratory. Ex periments have to be made under carefully controlled conditions. Thorough and accurate records must be kept.In making certain kinds of experiments in science v ariables are used. A variable is something which has different values under different conditions. In one type of laboratory test all the variables but one are controlled. This method of testing is called controlled experimentation. (535 words) (7) (27)。
