How to choose a chemistry reference book for junior high school?

The two-color pen at Longmen Bookstore is very good. Its body of knowledge is very detailed and can.

Chemistry is mainly about mastering chemical equations. This is very important.

Equations are like words in English.

Many chemistry topics, for example, calculation, inference, these two major problems, are based on equations, equations remember a lot, especially inference problems, can be made quickly, if you are not familiar with it, you have to think enough!!

Also, by memorizing equations, you will be better able to grasp the relationships between many equations. This doesn't show when you're learning. But when you're done with chemistry, you'll feel it.

Because you learn more, then the key equation you have to look for is smaller, so you must memorize the equation to learn chemistry well.

Preview is necessary.

The two-color pen at Longmen Bookstore is not good.

I think if you don't have a solid foundation in chemistry, it is recommended to buy more questions to do. If you are good at chemistry, you can learn the knowledge of high school, and junior high school is very simple.

In fact, it's the third year of junior high school, the knowledge that should be learned has already been learned What you need now is a thorough summary and induction process Now it's too late to do the exercises It's useless I suggest you buy a junior high school chemistry basics manual 60% of the high school entrance examination are basic questions Mastering the foundation is to master the lifeblood of the high school entrance examination.

If you want to practice the basics and master the knowledge points, it is recommended to win the championship gold version lightly, which has a detailed summary of the knowledge points; If you mainly practice the basics, you will win the silver version lightly, and you will practice more.

Chemistry is a kind of natural science, mainly at the molecular and atomic levels, studying the composition, properties, structure and change laws of matter, and creating new substances (the essence is molecules that do not exist in nature).

The world is made up of matter, and there are two main forms of change: chemical and physical changes (and nuclear reactions).

Therefore, their natural laws are also most closely related to the physical and chemical properties of substances and materials in the macrocosm of human existence. As an important bridge between the microscopic and macroscopic material worlds, chemistry is one of the main methods and means for human beings to understand and transform the material world.

Different from particle physics and nuclear physics, which study smaller scales, the basic properties of elements, molecules, ions (clusters) and chemical bonds studied in chemistry are the microscopic natural laws that are most closely related to the matter and materials in the macrocosm of human existence.

The universe is composed of matter, and as an important bridge between the microcosm and macrocosm of the material world, chemistry is one of the main methods and means for human beings to understand and transform the material world.

It is a discipline with a long history and full of vitality, which is very closely related to human progress and social development, and its achievements are an important symbol of social civilization.

I think it's a good thing to have a foundation and a high level.

Lightweight to win the championship, we all used this at the time, and it worked very well.

Chemistry "Five-year High School Entrance Examination Three-year Simulation".

Chemistry in the third year of junior high school is very simple, basically it is OK to listen carefully in class.

There is a teaching supplement "All Easy to Pass" is very good!

The Longmen topic is also good, and the knowledge points in it are very complete.

It's good to do the questions, sometimes you can see the answer at a glance when you see more questions, I have always been the first in chemistry from the third year of junior high school to the college entrance examination, but I haven't done many questions, you can study it more deeply, sometimes it feels fun, and it feels like everything is OK when you don't study.

The workbook of Qidong Middle School is very good, many questions will be examined, and there are many key points, I am also in the third year of junior high school, and I used it very well.

1. Chemistry Teaching Assistants for Middle School:"Complete Explanation of Secondary School Textbooks".

The content is relatively basic, and it is recommended to use it for preview. Preview and cooperate with the teacher in class to work best. Chemistry basically relies on it to learn by itself, driving and crushing classmates in class, and it has been learned once and the teacher repeats it again in class is more impressive, in addition, you can also use this book to help memorize chemistry knowledge points, it is advantageous to memorize more than others, and it is best to preview it during the summer vacation or the like.

2. Three points and one test

"Three Points and One Test" is a 2009 Science Press.

Longmen Shushi buried the book of Soukuan Ant Edition, the author is Xiyang. Each example question has a corresponding supporting exercise, and the classification of question types is very clear.

3. Complete interpretation of the textbook

Complete Interpretation of the Textbook".

It is planned by Little Bear Books and Queen Hung.

The editor-in-chief and published by Shaanxi Normal University Press is a teaching book that is completely synchronized with the textbook, which is the core product of the Little Bear book brand system.

Chemical Rush Method.

Instrumental knowledge points need to memorize element symbols, chemical formulas, and chemical equations.

Valency, atomic number.

The knowledge of regularity that needs to be memorized is: atomic structure.

The relationship with the properties of elements, the characteristics and charge laws of molecules, atoms and ions, the physical and chemical properties of various substances, the uses and preparation methods of substances, and the reaction laws between acids, alkalis, salts and oxides.

Skilled knowledge needs to be memorized: the key points of the basic operation of the experiment, the simple experimental design, the principles of material inspection, separation and purification, and the basic methods of the experiment.

With the rapid development of science and technology, chemistry is also developing with each passing day. Nowadays, more and more people are paying attention to chemistry and want to improve their knowledge by studying chemistry. So, how to choose the right junior high school chemistry textbook for you?

1. Choose teaching materials according to your actual situation.

There are many kinds of chemistry textbooks for junior high school, and different people will choose different textbooks according to their actual situation. For example, for those who want to quickly master chemistry knowledge, you can choose some more concise and easy-to-understand textbooks; For those who want to understand the principles of chemistry in depth, there are some textbooks that focus on theoretical explanations. In short, you should choose the teaching materials according to your actual situation.

Second, pay attention to practicality.

When choosing junior high school chemistry textbooks, we should pay attention to the practicability of the textbooks. This means that the textbook should be able to help us apply what we have learned in our daily lives. For example, we encounter some questions in our daily lives about the composition of the slag in food, water, and air.

If we can use what we have learned to analyze and solve these problems, we will be able to get practicality. Therefore, when choosing junior high school chemistry textbooks, we must pay attention to the practicability of the textbooks.

3. Pay attention to professionalism.

When choosing junior high school chemistry textbooks, we should pay attention to the professionalism of the textbooks. This means that textbooks should be published by professionals. For example, we can go to a library or bookstore to see if the publisher is a professional publisher.

In addition, we can also see if the publisher has the accreditation of relevant industry associations or institutions. In short, we should pay attention to the professionalism of its teaching materials.

If you have any questions about the self-test test, do not know the content of the self-test test center, and do not know the local self-test test policy, click on the bottom to consult the official website teacher and receive free review materials:
