I am about to enter the third year of junior high school, how do I study chemistry? How do I study o

Chemistry in junior high school is very easy to learn. Just listen carefully in class.,You can do whatever the teacher tells you to do.,When the time comes, the teacher will write some formulas of valence or something.,You just memorize it.,You have to memorize the equations you have learned.,Chemistry in junior high school comes and goes just a few times and it's easy to memorize the equations.,There are also some substances that have to be memorized in terms of color and shape.。。。 If you want to semester in advance, it is recommended that you go to the chemical periodic table, memorize the first 20 elements in order [the back of a cycle and a cycle (you can understand it as a line of back)] and then go to the Internet to find some other valence formula tables, by the way, the solubility table is also memorized (all a few lines, just dozens of words, the formula is super simple to memorize), if you can find the metallic order table, also memorize it...

The above let you be you don't carry it now.,When the time comes, you'll be asked to carry it when you go to school.,I only memorized it when I went to school.。。。 In the second half of the second semester of the third year of junior high school, it should have entered the total review (two books in the third year of junior high school, and the second volume seems to have started to learn last semester), and you do more questions when you review the total time, familiarize yourself with the topics, and gradually become proficient. This also allows you to get into the feeling early ...

That's pretty much it, what else to ask again!!

Pure handmade, tired to death...

First of all, you should be interested, and secondly, you should remember more. Only these two points can be learned.

Take notes carefully in class, I can take more than 90 notes every time I read the exam, chemistry is very simple, you have to follow the teacher's steps.

It's best to find a teacher to give you a preview in advance, the most important thing is interest, if you don't preview in advance, it's good to read the book and clarify the scope of chemistry to learn, after all, it is a new subject. If you have laid a good foundation at the beginning, chemistry will be easier to learn in the future. Remember to be understanding.

There are only a few knowledge points in each unit of chemistry, and those who change their memory must remember that some knowledge points are dead and must be tested every year. Hit to this extent so that you can use it flexibly. The most taboo is sloppy, so that you can't get a high score in the high school entrance examination.

Set yourself some time limits.

It is easy to get bored by studying for a long time, so you can divide the homework into several parts, and set a time limit for each part, such as completing the exercise within an hour, completing the test before 8 o'clock, etc., which will not only help improve efficiency, but also do not cause fatigue.

If possible, gradually reduce the time it takes, and soon you will find that what used to be an hour away can now be done in forty minutes.

Don't review the same subject all night.

I used to watch math or physics at night, and it proved that it was not only exhausting, but also ineffective. Later, I arranged to review two or three homework every night, and the situation was much better.

Except for the very important content, you don't have to take detailed notes in class. If you are busy taking notes in class, you will not be able to listen to the lecture efficiently, and you cannot guarantee that you will read your notes after class. The main work done in class should be to digest and absorb the teacher's lectures, and make some brief notes appropriately.

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.

Pay attention to experimentation and connect with reality.

Chemistry is an experiment-based science, and it will eventually be implemented in real life. Not only are many rules summarized from experiments, but the difficulties in the high school entrance examination are often set in the experimental questions. Observing seemingly ordinary experimental phenomena and thinking about the chemical principles behind them is the only way to solve experimental problems.

Chemistry in junior high school is actually quite simple.

At home, you can memorize element symbols, valences, and so on to learn to write chemical formulas and understand the chemical names of common substances in life.

That's probably what the first unit will talk about.

The main purpose of the preview is to figure out the concept, if you really feel that it is difficult, you can not prepare.

Not only will this not discourage self-confidence, but it will also prevent confusion from cognitive errors that can add to the confusion of formal learning later on.

Attending classes is much more effective than pre-studying. Be sure to listen carefully in class.

As a senior, I can tell you the difficulty of the chemistry exam in the future:

The more important laws: the law of conservation of mass, the atom molecule and some concepts of the order of metal activity, as well as the reaction conditions.

Metathesis reaction conditions (very engaging) Shanghai area must also remember that some alkali, salt solubility topics are mainly experimental questions, must be familiar with all the steps of several experiments required by the textbook and related purposes and precautions.

Looking at the graph analysis is also a difficult category, mainly focusing on the law of conservation of mass (pay attention to whether there is a precipitate or gas in the reaction process), solubility (very good. That is, the concept must be clear)

1. Reading books; 2. Do supporting exercises; 3. Ask someone for advice in time if you don't understand.

This preview is also not very useful, because I have not been exposed to it.

If you really want to, hide on the Internet and look at chemistry experiments.

And then there's the trim of equations and the conservation of elements, which in junior high school are a lot of tests.

Junior high school is the foundation, the knowledge is simple and easy to understand, it is best to go with this teacher, at this time, you should do the exercises in the book 5 to 6 times, one copy of the material is enough, and then a total review before the high school entrance examination.

It's very useful, I just got 60 points

Let's borrow notes from the previous session!
