Unexpectedly, the third day passed quickly. In retrospect, I still miss it. There are many papers and books sorted out at home. And the senior high school entrance examination is not as terrible as everyone thinks. It's just a simple exam, and then the third day is over. In the third year, how many reference books and papers did we turn over? Just for this exam, now I'm going to tell my classmates about how to learn junior high school chemistry well.
Experimental device
All right, let's not talk about these useless words. In fact, my chemistry level is not very high, but I hope that students who are about to enter the third grade can also have some of their own learning methods when learning chemistry, hoping to help you.
First of all, we should make the exam clear.
This sentence seems nonsense, but many people know this, but they can't do it. In fact, this is the basis for doing the problem. You should make clear the conditions given in the question before you answer. In the senior high school entrance examination, you often feel sad because you didn't get the basic score.
The second is to memorize the law of conservation.
The laws in chemistry are always the same, which seems useless, but it just tells you that this is a concept. You must remember that it can be used when calculating problems. And we must be conservative when writing chemical equations, otherwise this question will be wrong. So please remember the law of conservation and recite it to death.
The third is to find the reason.
In the exam, you will be given a new chemical formula in the general topic, which you haven't learned before, and this question is to let you understand this equation. Secondly, you can gain a new kind of knowledge, which is also very helpful for your future study. If you have this accumulation, your grades will gradually improve.
The fourth is to read more extracurricular chemistry books.
Generally speaking, I have been reviewing in the third grade, and I may not have time to read extracurricular chemistry books, so I can check the computer Baidu when I review at home and write it down by the way to enrich my knowledge.
The fifth is to lay a good foundation, which is the foundation of all knowledge.
Foundation is the foundation of all knowledge, which is very important for how to learn junior middle school chemistry well. Without foundation, you can't improve your later grades, so foundation is very important. There is nothing to say, just remember the basics.
Students do experiments.
Sixth, adhere to the experimental questions.
In the experiment, the first point is to consider the problem of excess, and the second point is to consider the gas when inhaling, and a small amount of liquid, such as water, will be brought out after passing through the liquid. The third point is to grasp the reaction phenomenon and so on. The fourth point is environmental protection and high efficiency, and the fifth point is to clean up impurities and not introduce new impurities.
The above are some methods about how to learn junior high school chemistry well. Please remember six o'clock. These are all prepared by our predecessors. I hope you can be admitted to your ideal high school!
