How to study physics and chemistry in high school?

I think it should be relied on feelings, the study of science, you need to have a lot of associative ability, why boys have an advantage in science, I feel that it is because boys are more naughty, because boys are naughty, because boys' curiosity will prompt boys to think, which will make boys' divergent thinking better. But the most basic thing in learning is interest, and being interested in a subject will make you learn twice the result with half the effort.

If you're a boy, I encourage you to be naughty, but not the mischievous kind, and of course it's very important to study seriously.

As a person who has come over, I would like to give you some advice, physics is to do more questions and be more familiar with various question types, because physics question types are relatively fixed, and the spatial imagination ability is quite demanding, and you need to imagine more ......In chemistry, the question type is fixed, but there are more small knowledge points, pay more attention to small knowledge points, as small as the physical properties of matter: color, density, ......Chemical reaction phenomena: color, precipitation, bubbles, exothermic and endothermic during the reaction, etc., ......Another thing to pay attention to in chemistry is to filter the information, grasp the useful information, and remove the information that interferes with the problem solving ......

Listen well in class and do more questions......It is best to prepare a set of questions for each subject......It's going to be easier to ......

Girls will be more careful, and if they are serious, they will learn very well......

Usually take notes carefully, physics is comprehensible, you don't need to memorize just a few knowledge points, chemistry should memorize more equations, and the formulas taught by the teacher and the like. There is nothing more important, the important thing is to listen carefully in class and complete the homework in time.

Physics and chemistry are not separated, and they are looking for relationships with each other.

Chemistry: Mainly to memorize some properties, write equations, etc. Textual things, you can take a look at it and memorize it.

The key to theoretical things is to understand, and if you understand it, you will be able to draw inferences from one another. For example, in a chemical equation, in order to write a correct chemical equation, you must first write the chemical formula of each reactant and product, and in order to write the correct chemical formula, you must understand the valency. If you just rely on rote memorization, it is still easy to forget when it comes to the exam, and understanding is the most important thing.

So you have to memorize more practice questions, such as multiple-choice questions, the teacher gives you some special properties to choose, so more practice can invisibly help you remember. The effect of light memory is not good. The more you practice the nature of those special substances, the more you will remember.

The big topic is reasoning, writing equations, and with a good foundation, you will not be afraid.

In short, it is a process of accumulation, the more you know, the better you learn, so memorize more and choose your own method.

Good luck with your studies!

High school chemistry is divided into inorganic chemistry and organic chemistry, to learn inorganic chemistry well, you must first master redox reaction and ionic reaction, although there are many reaction equations, but there are many things in common, you can list them together, compare and remember, you have to look at it repeatedly, organic chemistry has nothing to say, I believe you can read it well.

In the college entrance examination, the chemistry paper is actually very regular, and the selection of each knowledge point is basically simple, only one is difficult, and there are 4 major questions, which are organic chemistry, inorganic chemistry, chemical principles, and experiments.

Here's how:

1.Proficiency in the periodic law of the elements is the one in the second compulsory course, which is the law not the table, so that you can solve 85% of the chemical equations.

2.Inorganic chemistry: memorize the elemental elements of metal elements, non-metallic elements, the physical properties and chemical properties of common compounds, if you master the above 1, you will basically be OK with their chemical equations.

For example, reddish-brown powder, you need to know that it is Fe2O3

4.Principles of Chemistry: Elective 4, some people think it is easy, some people think it is difficult, and they don't know how to ask more classmates and teachers.

5.Experiment: In this regard, you have to accumulate more questions, not memorize, but do more, and I am deducting points for this question.

Textbooks are very important, and you should practice more questions on the basis of familiar with the textbooks.

First of all, I think it is important to develop an interest in chemistry as a subject. If your family conditions allow, I recommend that you buy a set of mainstream American high school science textbooks on Excellence.com, which is chemistry. Of course, other subjects are also very good, but they have nothing to do with chemistry.

Then read more popular science books on chemistry, so that on the one hand, you can expand your knowledge of chemistry, and on the other hand, you can deeply feel that chemistry is not only interesting, but also more useful.

Secondly, buy a chemistry reference book with detailed explanations, prominent difficulties, and clear ideas. Another point is that the book you buy must be something you like, otherwise you won't have a strong interest in it and read it often, remember, it must be what you like and want from the bottom of your heart.

Thirdly, you should go from easy to difficult when doing the questions, so that you will have a great sense of accomplishment, and the more accomplished you are, the more you want to continue learning, which forms a virtuous circle.

Then, if you want to master the knowledge points, I suggest you read the Chemistry Basics Handbook; If you want to do classic college entrance examination questions, I suggest you watch the five-year college entrance examination three-year simulation.

Finally, I sincerely wish you a good study of chemistry as soon as possible, thank you.

The way to improve your score in a short period of time is that if your score is less than the passing line, you will grasp the concept and grasp the basic question type, if your score is in the passing line to the excellent line, do 20 big questions a day, it is necessary to meet the test standards, don't bother yourself with the competition, it is best to only do it yourself, you will not do it will be annoying, if you understand the basic question type, it means that the concept is familiar, do some questions that you can do to enhance your confidence, but not too simple.

If you want to learn physics easily, it will take at least half a year, of course, if you have a strong comprehension ability, but you don't know how to face the problem, then the time can be less.

The first is to summarize the main points of your knowledge, physical mechanics and electromagnetism, accounting for 80% of the points, generally except for electricity, it will not be too difficult, mechanics includes the important thing is the conservation of momentum, the conservation of mechanical energy (I personally prefer the conservation of energy, but the range is large, unconditional, but relatively few people can accept), electromagnetism, must be proficient in judging the right-hand rule, the most prone to error.

In addition, a formula is a thing that is easy to harm people, remember, it is very simple to be proficient in a formula, when you do a problem, you substitute each value of the formula into its unit, just like a fixed number, the left and right sides must be the same unit. After doing this for a long time, think about the formula S=VT(M=M S*S), v=at(M S=M s 2*S), or G=MG(N=KG*M s 2), of course, you need to know some basic unit conversions. n=kg*m/s^2)

In fact, high school physics is only very basic, it is not like Chinese English to memorize a lot of things, nor is it like mathematics that exhausts the method, but many people are very reluctant to accept an unfamiliar subject, don't be afraid, physics is still physics, it is just a subject derived from mathematics, much simpler than mathematics.

You don't need to listen to the teacher talk about the concept in class, but you must spend a little time to listen to the teacher's lectures, and some people have said that you can listen to the teacher, but you can't do it yourself, you must not copy notes, then you will not be able to keep up with the speed, follow the teacher's train of thought, and then bury your head in the notes, and eventually you will become lost. Generally, it is good to spend ten to twenty minutes listening attentively in a class, remember the concept after class, don't do too many questions, and do one question, which is better than a hundred questions, don't bother yourself with the questions. Do a little, but if you can't do it, you must remember that it is to remember where you stopped, not to remember the topic.

Ask your teacher to send you the information.

Or you can look for exercises to watch.

Electromagnetism is indeed more difficult, more difficult than the analysis of force, but master the analysis method, the formula must be memorized, the textbook example questions and after-class questions should be analyzed thoroughly, and the usual exam summary Oh, it is absolutely no problem!

Take good notes in class, keep up with the exercises after class, memorize formulas, buy a good tutorial book, be good at thinking, and have more connections with life.

That's all right.
