Chemical calculations are very difficult, new learning in the third year of junior high school, not

If you can learn physics well, then chemistry must be no problem.

Actually, it's easy to learn chemistry well.

First of all, master the knowledge points in the book, and secondly, do more questions to deepen your understanding.

In fact, these two steps complement each other, and you can deepen your understanding of the knowledge points by doing questions; If you want to know if you really understand, you can test it by doing questions.

This is the most effective and efficient method, but don't do the questions blindly, do some typical questions, do some exam questions.

It's impossible to learn chemistry well without doing questions, just like physics.

Be calm, don't be impatient, take your time, and you'll learn well. I think mindset is the most important thing.

Take a look at the classic examples

Memorize chemical equations, pay attention to reaction phenomena, and summarize some reaction rules by yourself, such as solubility and redox.

It is often said that chemistry is a liberal arts subject in science, and I usually strengthen my memory of concepts, do more exercises, and slowly pull it.

It's good to memorize the chemical equations.

Chemistry belongs to the liberal arts in science, and to learn chemistry well, you must first memorize each knowledge point, and at the same time be able to connect each knowledge point to form a knowledge network, which is very important for the understanding of knowledge. secondly, do more typical questions to deepen your understanding, but don't do them blindly; Finally, do the test questions, prescribe the right medicine, and get twice the result with half the effort!

First of all, you should give yourself confidence, there is nothing difficult in the world, as long as you are willing to climb.

Secondly, analyze the reasons why I can't read, in my opinion, there are two reasons, one is that the foundation of this knowledge point is not solid, and we should start from the foundation and work step by step. The second is to have a correct mentality, whether it is to do the problem or not, You Kai can do everything with a good attitude in order to do better, and emotional stability can play extraordinary.

The basic things are not memorized, and it is not very good for analytical reasoning. Fourth, pay attention to experiments and operations. Communicate more with teachers and classmates, talk more than watch more, and only by communicating can you understand the essence of the problem.

Whenever we want to learn something, we have to find a breakthrough, why should we learn? What's so interesting about it?

<> say 1,000 to 10,000, it depends on the child himself, mastering the method and working hard is a road to learn all disciplines well, there is no shortcut, the premise of learning chemistry well is that you have to treat it like a friend to understand it, know it, so as to "coexist peacefully". If you memorize the periodic table of chemical elements, take every chemistry class, do every chemistry experiment, and memorize the evolution of equations, you will definitely get good grades. After class, if you can basically master the basic knowledge and skills you have learned in class, you will not have difficulty reviewing and doing homework after class.

Junior high school students have a strong memory, have a firm grasp of basic knowledge, and are easy to learn when they rise to theory. 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. After-class exercises are important.

I remember that when my sister was studying chemistry, she carefully did all the after-class exercises before the exam, and she scored more than 90 points. It's like memorizing English words. Of course, some of them should be memorized on the basis of understanding, so that the effect will be better and will be remembered for a long time.

After all, chemistry is a natural science. Because the format of the exam is changeable, you need to be well-informed in order to be able to adapt to all changes in the same way. Put on a set of Wenchang pens that can prosper Wenchang, and you can make progress in learning, improve your learning luck and exam luck, and "open up" as soon as possible.

Many students may have difficulty in experiments, so they need to practice more or observe more practice. Interesting chemical events in life can cultivate interest in chemistry learning, such as the story of ghost fire - the combustion of white phosphorus. Therefore, many children are not adaptable, although chemistry is said to be a liberal arts subject in science, but it still needs to be understood, and it should be reviewed in time after listening to the class.

Keep up with the teacher's pace in class and don't ignore every detail and what the teacher emphasized.

You can memorize the chemical equations first, and then combine the books to learn the basics of chemistry, you can listen carefully, and then recite what the teacher said, and then do the questions after learning the basics, and the efficiency will be twice the result with half the effort.

Personally, I think that chemistry in junior high school is not too difficult, and the skills are: first, you don't need to have psychological pressure, because it is some basic knowledge, and second, you need to rely on memory and understanding of experimental equipment, so that you can master the correct learning method.

I don't think you should be too anxious about the study of this subject, you must grasp the foundation is the most important thing, and memorize the ingredients and formulas of various elements.

The first thing you should understand in junior high school chemistry is to master each equation, and to know the meaning of each symbol, and to memorize some of the things that the teacher has said and the knowledge she has taught, so that you can quickly master it.
