How can I learn chemistry well?

I'm going to take the entrance exam too

This stuff is based on personal experience, and it can be used flexibly, and you can test some experiments yourself, and there is more

Anyway, it's hard to pull!

Everything will be fine!!

I'm also in the third year of junior high school, and I'm a multiple-fold chemical reaction equation and reaction phenomenon, as well as solubility and the like, and my grades are the first in the class, I think this is more effective, if you are interested, do more questions in the middle school exam.

Hello classmates, if you are in chemistry, just listen carefully to the teacher in class, and then finish the materials and homework sent by the teacher. If you want to get a high score, I suggest that you buy a few chemistry reference books and exercise books by yourself, study them yourself, and ask your teacher if you don't know the answers. Chemistry depends on the tactics of the sea of questions, see more questions, do more questions, in order to memorize and solve the problems quickly and accurately.

Hope you are satisfied.

Is the landlord a junior high school student? If yes, memorize more chemical equations, listen carefully in class, or play chemistry poker. I don't know about it in high school.

Read more books, memorize more basic knowledge, summarize more questions, ask teachers more, and think more for yourself.

Read more books and do more topics, try to make yourself interested, then it is not far from learning, I wish you a good study as soon as possible!

1. Listen carefully and take good notes.

Good notes are the condensation, supplementation and deepening of textbook knowledge, and the presentation and refinement of the thinking process.

Since the knowledge points of chemistry are numerous, fragmented and scattered, in addition to listening carefully and thinking positively, in addition to listening carefully and thinking positively, we should also write down the key and difficult knowledge of the teacher in our own words on the basis of understanding, so as to facilitate future review.

2. Review in a timely manner.

Revision is not just a simple review of knowledge, but considering the interconnection of old and new knowledge in one's own brain, and reorganizing it to form a new body of knowledge. Therefore, after class, it is necessary to review the content of the lecture in a timely manner, and do a good job of sorting out and summarizing the knowledge, so as to make the knowledge integrate and avoid the phenomenon of more and more chaos in learning. For example, if you learn about the bleaching properties of SO2 and chlorine water, you can compare them to find out the differences.

3. Learn to memorize.

Since there are many chemical knowledge points to memorize, it is difficult to memorize them if you rely on rote memorization, so you should learn to memorize them skillfully. The commonly used memorization methods in chemistry are: comparative method (often used for knowledge that is easily confused and interferes with each other.

The four similar concepts of isotope, allotrope, homologue, and isomer can be deepened and remembered through comparison. ), induction, song recipe memory, comprehension memory, and experimental memory.

Fourth, practice diligently. Practice is an important way to understand, digest, and consolidate classroom knowledge. However, the practice should be targeted, not a sea of tactics, and should be aimed at mastering the basic methods and the rules of problem solving. In the process of problem solving, it is necessary to pay attention to multiple solutions and inductive summarization of one problem, so as to achieve the effect of doing one problem and one category.

For example, the techniques commonly used in chemical calculation include: conservation method, relational method, extreme value method, average value method, estimation method, difference method, etc.

5. Prepare a "mistake book".

The purpose of the questions is to develop abilities and find effective ways to find your weaknesses and deficiencies. Therefore, mistakes should be corrected and recorded. When recording, you should analyze the reasons for the error and the correct solution idea in detail, and do not simply write an answer.

At the same time, it is important to go through the review frequently so that you can avoid similar mistakes in the future.

6. Pay attention to chemical experiments.

Chemistry experiments can not only cultivate students' observation, thinking, hands-on and other abilities, but also deepen their knowledge and understanding of related knowledge, so we must pay attention to chemical experiments. When doing experiments, we should ask a few more whys, think about how to do it, why we do it, and what else can be done, so as to achieve the purpose of "knowing what it is and why it is true".

In addition, in order to study chemistry well, we should pay more attention to social hot issues and life problems related to chemistry, and be good at combining book knowledge with practice.

In short, as long as the learning method is correct, I believe that students will easily learn chemistry well.

Tell me about your own feelings, which may not be right for you, but it's worth a look. For the study of chemistry, many people ignore one point, that is, we cannot give up the basics, that is, the properties and characteristics of various elements and substances, and the principles and characteristics of various reactions. Just like many people memorize chemical equations, which is painful and confusing, if you have a good understanding of the principles of various reactions, remember the properties of all the elements in the syllabus.

Then you don't need to memorize any chemical equation, because you can reason it out on your own according to the properties, and you can't be wrong except for a few exceptions. I'll give you an example, in general, chemistry focuses on the basics, collecting more about the various properties of each element and memorizing them, understanding the principles of each reaction, you might as well spend 30 minutes and a lot of equations looking at these basics. I hope my answer will help you.

It's not difficult, it's not difficult at all, lay a good foundation first, and you will feel uncomfortable at first, because this is a new discipline and I don't know it. But it's very interesting, as soon as you memorize the knowledge and repeat it more, you will feel that the more you learn, the easier it will be, and you will do more classic questions. Ask the teacher more, and if you don't understand, you must ask to understand, and you will feel very simple.
