For high school physics, how do we review the experiments

1.Each experiment is carefully understood from 7 aspects: experimental purpose, experimental principle, experimental equipment, experimental procedure, data processing, precautions, and error analysis, and some corresponding exercises are made.

2.Pay attention to the readings and use of some measuring instruments that are often tested, such as vernier calipers, spiral micrometers, etc.

4. Pay attention to the commonality and individuality problems of electrical experiments.

For example, the selection of instruments, the connection method of the ammeter (internal or external) when measuring the resistance by voltammetry, and the connection method of the sliding rheostat (voltage division or current limiting), etc.

You don't need to do it yourself, and I don't think many schools have this condition to let everyone try. To put it bluntly, it's better to deal with the exam. First of all, you should classify the experiment according to the knowledge points, and then master the relevant knowledge points first, and then do more relevant exercises, I believe you will be able to make a qualitative leap.

Secondly, it is to establish the confidence that you will do it, if you don't have confidence, it is useless to do more questions.

Do the experiments yourself. The experimental principle is tested through experiments.

The experiment is mainly to understand the principle of the experiment, and then there is to distinguish what kind of experiment is to do, because many problems are set on this basis, and there are usually multiple types of questions, and those who do not understand or have difficulties need to be paid attention to are recorded in the notebook, which can be reviewed, and the main thing is to understand each step and practice of the experiment.

There are two main parts of physics experiments: mechanics and electricity.

When you review, you pay attention to the block to review, the main force of mechanics is the synthesis and decomposition, the synthesis of motion, the flat throwing motion, the dot timer ** uniform speed linear motion, strobe photography, verify the conservation of mechanical energy, verify the conservation of momentum, etc.

Electricity is mainly a chapter on constant current. It's good to sort it out when you're revising.

Do the experiment again.

Reading. I don't know how to ask the teacher. The most effective way.

In high school, physics experiments are very important, how to learn physics experiments well? Today I will make a simple attempt at this problem, hoping to help friends in need.

1.It is necessary to clarify the purpose of doing physical experiments

The purpose of our physics experiments is to grasp some basic knowledge of physics more effectively through practice, and learn some experimental skills, and understand the structure of experimental instruments, their principles and how to use them in the process of doing physics experiments. Therefore, physics experiments have always been regarded as a good opportunity to cultivate and exercise students' hands-on ability and ability to work independently. In addition, it is also necessary to understand the purpose of each experiment, such as understanding the morphological phenomenon of a chemical substance.

2.Master the methods of experimentation

If you want to learn physics experiments well, you must understand the key steps of the experiment and the method of showing the experiment, understand the performance of the device to be used in the physical experiment, how to adjust and pay attention to the precautions for doing the experiment, and know the whole process.

3.Learn to think in the process of conducting physical experiments

The purpose of doing physics experiments is mainly to be able to grasp the basic knowledge of physics faster, which requires students to ask more whys in the process of doing experiments, and at the same time carefully observe various phenomena and data in the experiments, and think more about the causes of these phenomena.

4.Do a good job of analyzing and summarizing the physics experiment after the end

In the process of conducting physical experiments, it is not enough to simply record some basic experimental phenomena, and after the end of the experiment, it is necessary to summarize the measured data and summarize the physical laws, so as to be able to write a good physical experiment report, truly grasp the purpose and principle of the experiment, and lay the foundation for future experiments.

The first is to lay a good foundation for physics, and physics experiments are also models based on physical knowledge. The physical experiments of the high and high school slag belts should be simplified. Think about how you can get rid of unnecessary factors and get to the main point.

Usually, I deduce the commonly used formulas such as Xunlu a few more times, so that I will not be messed up.

Master the basic physics knowledge, the teacher takes the students to do physics experiments to ensure safety, and the things used have strict regulations, so that they can learn physics side base experiments well.

Carry out a variety of classes, so that professional teachers can take children to do experiments and master basic physics knowledge, so that they can learn physics experiments well.

During the lesson, you should listen carefully to the lectures, and you should also try to take good notes, and you should also pay attention to the precautions when doing experiments.

The main purpose of mechanical experiments is to grasp the experimental principle of each experiment, that is, the basis of the experiment, and to analyze the physical quantities that need to be measured and the methods to reduce the error from the principle.

The electrical experiment is mainly the analysis of the power supply circuit

1. There are two solutions to the sliding rheostat: current limiting method and partial crimping method (you have to be able to draw circuit diagrams) The voltage starts from zero to divide the voltage--- and the voltage is divided from zero.

The resistance value of the sliding rheostat is less than the measured resistance to divide the voltage--- to divide the voltage to become smaller, the range of the minimum current exceeding the standard must be divided--- the meter must be divided 2, and the voltammetry method will analyze the internal and external methods.

Flexible application: If the internal resistance of the meter is known, how to accurately measure the resistance of the resistor, how to accurately measure the resistance of the resistor, how to accurately measure the resistance of the resistor.

How two voltmeters accurately measure the resistance of a resistor.

3.The internal resistance of the gauge:

Voltammetry semi-biased method.

Equivalent substitution. Categorize electrical experiments.

For example, the volt-ampere characteristic curve of a small bulb is measured.

Resistivity of the side metal.

Measure the electromotive force and internal resistance of the power supply.

In fact, the principle is similar to voltammetry.

Master some basic analysis methods first, and then apply them flexibly.

There are too many contents to explain clearly, I think you should still find a teacher to make up for it, and you should think a lot about it to have a reward.

You should not be diverted by your own will, you should think of yourself as the person who did the experiment, consider from the standpoint of the person who wrote the question, according to and recall the derivation content of the teacher's lecture in class, learn to apply the type of question you have seen, and draw inferences from one another.

Understand the BAI circuit diagram, which is the Shenma node DU method, when you can understand the node method--- that is, understand the DAO circuit diagram, take over the version.

Just do more questions down.,Right, especially in the mock exam papers.,Back and forth electrical experiments on those few question types.,If you don't make a mistake in the calculation, you can pass it casually.。。。 I just finished the college entrance examination last year.,I didn't get your say.,Physics has become easier and simpler in recent years.。。。

The most important thing in the electrical experiment is to measure the resistance and electromotive force and internal resistance by voltammetry, and the key is to master the internal and external connection methods of the ammeter and the voltage division, current limiting connection method and conditions of the rheostat.

Take a good physics experiment review class in the third year of high school:

1. Understand the characteristics of the content of the college entrance examination experimental test in recent years.

2. Strengthen the teaching of the use of basic instruments.

3. Re-examine and combine experimental sectors from multiple perspectives.

4. Pay attention to the exercises and demonstration experiments in the textbook.

In teaching, it is necessary to attach importance to the study of physics experiments, strengthen the guidance of students, and enable them to truly understand the essence of physics experiments, so as to promote the learning of physics.

See more, practice more, think more, ask more.

Physics is a science based on experiments, and many important laws, concepts and theories in physics are summarized through experiments after analyzing, inducting, comparing and synthesizing a large number of physical phenomena. Physics experiments are an important aspect of physics learning. As a physics laboratory teacher, I have deeply realized the important position of physics laboratory teaching in physics learning over the years.

So what? The first step is to recognize the role of high school physics experiments. The first is to be able to deepen students' understanding of physical concepts and laws.

Although the teaching process is a special cognitive process with indirect knowledge as the object, it still needs to follow the cognitive law from perceptual to rational and from practice to theory. Physics experiments can provide students with a wealth of perceptual knowledge and practical opportunities to understand physics knowledge. Marx said that "physicists examine natural processes where they are most reliably and least disturbed, or, if possible, on conditions that ensure that they are carried out in their pure form".

Due to the "most reliable and least disturbed" characteristics of physical experiments, physicists can well discover and understand the laws; Similarly, physics experiments can create a suitable physical environment in the classroom, so that students can master physics knowledge in the most effective way. Secondly, physics experiments are helpful to the development of students' abilities, and the development of students' abilities is an important task of teaching reform. The development process of modern science shows that experiments are an important foundation for the development of science, and without the phenomena shown by experiments, it is difficult to break through the shackles of traditional concepts.

In teaching, allowing students to use both their hands and brains to explore and verify the laws by themselves is conducive to the development of students' thinking, intelligence and ability. For high school students, it mainly refers to the ability to formulate experimental plans, steps, design records, reasonably select instruments, correctly use instruments for measurement, analyze and sort out experimental results, and draw necessary conclusions according to the purpose and requirements of the experiment. In fact, students' experiments are the process of comprehensive training of thinking ability and experimental ability, and it is also the source of students' creative ability.

We should understand the role of students' experiments from the interrelationship between practice and thinking, hands-on and brain-moving. Secondly, student experiments are conducive to students learning the methods of scientific experiments. Physics experiments can imitate the research process of physics to a certain extent, allowing students to actively learn and explore physical laws, and learn scientific research methods, such as methods of exploring physical laws (exploratory experiments), methods of verifying physical laws (verification experiments), and methods of idealized experiments.

Student experiments can deepen students' love for physics and further stimulate their interest in physical science. Through student experiments, students can establish a scientific attitude of respecting objective reality, being serious and meticulous, and can form a good experimental habit of doing experiments in accordance with the use methods and procedures of basic instruments and experimental requirements.

So much is theory. Ha ha.

First of all, what do you want to think about in the lab class?

Generally, the experiments are laid around the teaching of theoretical courses, in order to strengthen perceptual understanding.

If you want to study in depth, you can refer to some content of ordinary physics experiments.

To put it simply, to take a good experimental class, it is to grasp a problem, understand it thoroughly, and understand it thoroughly.

First, starting from the basic formulas and definitions, we should find ways to deal with experimental problems in multiple ways and directions.

Second, the same experimental purpose, through the transformation of experimental equipment, guide students to change their thinking tentacles, communicate and synthesize multiple knowledge points with each other, and deal with problems flexibly.

3. Diverge the use of instruments that everyone is familiar with, and cultivate students' thinking of seeking differences.

Fourth, pay more attention to guiding students to use one thing for multiple purposes, give full play to students' imagination, and tap students' experimental potential.
