How to improve your chemistry scores in junior high school, how can you learn chemistry well?

Do more wrong question books, carefully analyze none of the questions, ask questions if you don't understand, memorize the conditions of various reaction types, remember the inspection and identification of some special ions, of course, the premise of these is that you can write chemical formulas.

In various disciplines, chemistry is relatively easy, it is said that chemistry is a liberal arts in the sciences, which means that chemistry needs to memorize and understand more knowledge, so to learn chemistry well, we must first understand and firmly grasp the concepts, the properties of elements and various molecules or substances, the reaction laws between substances, the order and law of the periodic table and so on. Secondly, chemistry is more abstract, and it is necessary to understand the composition of molecules, atoms, etc., the rules of electron arrangement and motion, and the relationship between the gain and loss of electrons and chemical properties; Third, we must do a good job in the experiment, grasp the purpose of the experiment, the required experimental equipment, the experimental procedures, the matters to be paid attention to in the experiment, and the mistakes that are easy to make; Fourth, the method of identifying chemical substances is very important, and it is necessary to read more textbooks, practice makes perfect.

If you want to learn chemistry well, you must first memorize a lot of physical properties, chemical properties, and the phenomena and reaction conditions of the chemical reaction. This is the foundation, and then the relevant laws of change and nature evolution must be summarized.

Find a teacher to tutor, and ask the teacher to make a study plan for you, so that your chemistry subject will improve quickly.

An easy way to master exam skills is to find one or two models and previous years' high school exam questions from now on, and do a few sets carefully to find out the pattern of the exam every year. If there are questions in the test, the teacher must make sure to ask the questions in time. After doing almost all the exam questions over the years, I found that there was no chemistry question!

Also, believe in yourself and have plenty of time. Be diligent and look forward to being been.

First of all, the knowledge of elemental compounds about some equations needs to be memorized and memorized. Elemental inference questions, pay attention to grasp the routines, such as carbon, oxygen, carbon monoxide and other conversion problems. If you want to calculate the problem, you can write down the relative molecular mass of several molecules if possible, and when you do this problem, you will have more time.

You need to brush the questions, you can consolidate your foundation, and mathematics is a truth, and then to understand and learn, memorize the basic knowledge points when you read in the morning, work harder than usual, work harder than others, and slowly get better.

It is not very difficult to learn chemistry well, first of all, memorize some basic knowledge. For example, element name symbols. Chemical Formula. and writing relevant chemical reaction formulas, etc., and memorizing them first, relatively speaking, it will be easier.

1.Class notes. Class notes are a form of attentive listening. Class notes are suitable for recording key points, key points, and difficult points, and the reasoning process of related content, as well as Yuan Xi's humorous language to deepen a certain knowledge.

2.After-class notes. By after-class notes, I mean that taking notes in class cannot be complete and complete, so they should be left in class notes.

I think you still need to listen carefully to the teacher's lectures in this chemistry subject. And not only do you have to listen carefully to the teacher's lectures, but you also have to actively participate in the experiment and make experimental records. In this case, chemistry should still not be so difficult.

Chemistry in junior high school only requires a good grasp of the equations in the book, and then it is enough to be able to calculate simple problems.

Junior high school chemistry is generally based on memorization, the physical properties of various substances, gas color, odor, liquid color. Chemical equations are the most important thing, just memorize and memorize.

If you want to improve your chemistry scores, the easiest way is to lay the basics well, and then resolutely don't go, say some wrong questions, and get the marks you should get.

Listen carefully in class, and then brush up on the questions more, if you don't understand, make a note, and review it every day.

The basics must be solid, because the current exam questions are very flexible and will not be something to memorize. It is an examination of the flexible use of knowledge.

Coming to the third year of junior high school, for the course of chemistry, it is a process of accumulation over time, whether it is his equations or some experiments, it is necessary to accumulate for a long time to learn, if you want to improve, you must lay a good foundation.

How can I improve my current grades in chemistry in the third year of junior high school? Immediately in the third year of junior high chemistry, the grades should read more books, memorize, theorems, definitions, and remember chemical reactions.

Chemistry is very simple, you need to listen carefully in class when you first start class, memorize more chemical formulas, chemical equations, etc., junior high school chemistry is mainly based on memorization, and there is not much skill at all.

Study hard, but there is a way to learn, don't be reckless in learning, often analyze yourself ** have not learned, focus on overcoming. Do a real understanding of why this is the way it is and why it is the way it is.

I think that since I am about to enter the third year of junior high school, if I want to improve my chemistry subject, I should make up for it, and maybe there will be a chance.

How to improve the chemistry scores of junior high school students quickly The following is based on the subject characteristics of junior high school chemistry, combined with my years of teaching and learning experience

It is recommended to take a good look at the online tutoring, because you may really not understand what the teacher says in chemistry, and ask more questions to your classmates and teachers.

Read more and study more, buy more books for this kind of purpose, or go online to buy them.

Nowadays, many students want to know how to learn junior high school chemistry well, and they don't know where to start when they learn this course, this problem is very difficult for them, now let's find out how to learn junior high school chemistry well!

Chemistry is a basic discipline that studies the composition, combination, and change of some special substances, and it has a very great role in agriculture, society, science, etc.

How to learn chemistry well in junior high school?

1. Understanding. When learning these courses, you need to understand the concepts and theories, which are necessary knowledge points for learning all courses, and you also need to have a very good foundation, generally these concepts are expressed in very simple sentences, so you need to grasp the key, and then memorize.

For example, catalysts, a concept that generally requires comprehensible memorization such as sum, equality, and so on. These concepts not only need to be correctly understood, but also need to be used correctly, and generally speaking, chemical professional terms refer to some sentences expressed in the experiment, such as element symbols, etc., which are all content to be fully mastered and used correctly.

2. Structure. In this course, it is necessary to know the structure of the object under study, which is directly related to the nature of the object under study, and the nature will affect the state of existence and use of these substances, so it is necessary to grasp the structure of these substances to make judgments.

For example, oxygen, you need to think about what it is made of and what space it can exist in, what kind of substances will cause abnormal reactions, and under what circumstances it will cause harm to the body, etc.

3. Test. In the study, the test accounts for a large proportion, the students need to carry out their own work, need to know how to separate, purify, identify, etc., in the analysis of the need to draw certain conclusions through some specific means, in the use of the instrument needs to be careful, in the process of doing as correct as possible, the results should be more obvious, in the teacher demonstration needs to be patient observation, a comprehensive understanding of its principle, so that they can carry out the test without error.

4. Learn the law. When studying, you need to find your own learning style, there are many contents in these courses, so if you don't study properly, your score may drop, and it is very important to find your own learning style.

The above is about how to learn chemistry in junior high school, I hope the above content can help you when students learn chemistry.

First of all, you need to read a book, understand the concept, memorize the chemical equation and master the method of trimming. Secondly, brush the questions. There is not a lot of chemistry content in junior high school, and you should be able to review it in a month. Come on

Don't worry, because I came here to make people I used to have about 60+ in biochemistry, and now I have 80+ in the exam, the reason is very simple, zhi is to read books, return to dao textbooks, books can not only allow you to improve your interest in biology, the important test points and the content of the test are in it, but also to do the questions appropriately, I hope it will help you. If this is not good, it is recommended to find a chemistry tutorial class, there are quite a lot on the market now, one-on-one tutoring is relatively effective, like 100 education, ** are according to the student's personal situation for the corresponding teaching, so the effect is still good, it is recommended that you try. Finally, I wish you all the best in improving your chemistry scores.

If you want to learn chemistry well in less than a year, you must not only pay attention to it, but also master scientific learning methods. Below I have summarized for you how to learn chemistry in junior high school and the tips to improve your grades, just for your reference.

Good at listening to lectures and taking notes.

If you want to learn chemistry well, you must first understand this course. For this reason, you can use the summer vacation to read through the chemistry textbook first, maybe the interesting and lush chemistry textbook will deeply attract you. In addition to reading the content of the new lesson carefully, you should also mark the areas you do not understand, and try to do the exercises in the textbook.

In this way, with questions and difficulties, the efficiency of listening to the class will be greatly improved.

There is a lot of chemistry content in junior high school, and teachers focus on key content when they give lectures. Therefore, it is necessary to listen carefully to the class and take notes carefully, which is not only conducive to reviewing after class and mastering the key points, but also can effectively prevent "distraction" during class. However, when taking notes, it is necessary to pay attention to the method, and on the basis of listening to what the teacher says, you must remember the key points, difficult points, doubts, and things that are not in the textbook.

Thoroughly understand textbook knowledge.

Taking the textbook as the main line and carefully reading the textbook is the foundation of learning chemistry well. To this end, it is necessary to be good at reading textbooks, so as to read before class, read carefully after class, and often select reading, etc., and pay attention to the main content, but also do not ignore the small print part and some charts and optional content, because these contents help to deepen the understanding of the main content and broaden the scope of knowledge. When reading carefully after class, you should read and remember while thinking, and strive to solve all the unsolved problems in the preview and listening to the class.

Regular reading refers to selective reading of important or difficult to fully comprehend content. At the same time, through various forms of reading, it also helps to improve self-learning ability.

The content of junior high school chemistry is closely related to life and production. This requires that while learning chemistry, we should try to connect with the reality of production and life, discover chemistry from the life around us, and experience chemistry, so that the more you learn, the more you want to learn, and the more you learn, the more you love learning.

Junior high school students should pay attention to experiments.

Chemistry is an experiment-based discipline, which can not only stimulate our interest in learning, but also is very important for us to form chemical concepts, understand and consolidate knowledge, train experimental skills, cultivate observation and hands-on ability, improve thinking and solve practical problems.

This requires careful and meticulous observation of the teacher's demonstration experiments, and the instruments, drugs, devices, experimental principles, steps, phenomena and precautions used in the experiments must be clear and memorized. At the same time, students should do a good job in student experiments, interesting experiments and family experiments, and actively participate in extracurricular activities in chemistry, such as visits, lectures, chemistry games, etc., to actively cultivate their interest in learning chemistry.

Chemistry is a discipline that begins with"Experiments"It is a basic discipline and a large amount of knowledge requires the characteristics of memorization. Below I have summarized for you how to learn chemistry well in junior high school and improve your grades, just for your reference.

It is necessary to pay attention to the basic knowledge of chemistry.

If you want to learn chemistry well, you must be proficient in the basic knowledge, and mastering them can lay a good foundation for learning about elemental compounds and acids and alkalis in the future. The foundation of chemistry is very important, especially junior high school chemistry, many of which are new to students, to learn the basic knowledge of chemistry accurately, learn fine, don't feel that the foundation is simple and boring, this is a wrong understanding, simple foundation is the first step to learn advanced chemistry in the future.

Good at listening to lectures and taking notes.

If you want to learn chemistry well, you must first understand this course. Be sure to preview before class, in addition to reading the content of the new lesson carefully, you should also mark the areas you don't understand, and try to do the exercises in the textbook. In this way, with questions and difficulties, the efficiency of listening to the class will be greatly improved.

There is a lot of chemistry content in junior high school, and the knowledge is relatively scattered, so teachers focus on the key content when lecturing. Therefore, everyone should listen carefully to the lecture and take notes carefully, which is not only conducive to reviewing after class and mastering the key points, but also can effectively prevent "distraction" during class. However, when taking notes, on the basis of listening to what the teacher says, you should remember the key points, difficult points, doubts, and things that are not in the textbook.

Learning Methods for Chemistry Experiments.

1) Experiments are a means of learning chemistry. Experiment is a scientific method for studying chemistry, and it is also an important means to learn chemistry.

2) Observation and experimentation should be combined with thinking. The observation of chemical experiments is generally carried out in the order of "before the reaction, during the reaction, and after the reaction", and at the same time, it is necessary to actively think and analyze the essential problems through the phenomenon.

3) Remember the necessary steps in the operation of chemical experiments, and do not be sloppy.

4) Experimental questions are compulsory in the chemistry exam, so in the usual learning and review process, the experimental knowledge learned should first be summarized and summarized to form a network. The high school entrance examination generally examines the basic concepts, to understand and classify, and to grasp the properties and important relationships of several important substances, such as oxygen, hydrogen, carbon and its compounds, acids, alkalis, and salts. Secondly, it is necessary to classify and summarize some of the chemical experiments learned, such as the classification, use and basic operation of chemical instruments, and also master the calculation of basic chemical formulas and chemical equations.
