Anonymous users2024-02-06My junior high school chemistry is very good, so I think junior high school chemistry is not difficult at all, as long as you memorize the basic chemical formulas by heart, and there are some changes caused by reactions, such as precipitation, smelly gases. Wait a minute. Look carefully at the question stem when doing each question, and some will have hints.

Anonymous users2024-02-05Hello, I think chemistry is relatively simple to learn, textbooks are the most important, the following provides some learning methods, is some of my experience, I hope it will be helpful to you.
Chemistry Total Review:
First, always start from the textbook, start from the basics, no matter how many questions you do, the foundation is not good, and at the same time, you must refine the textbooks, eat the textbooks thoroughly, and do the after-class practice questions
Second, there is also the fact that you have to follow the teacher, the teacher is the most direct way for you to improve your grades Listen to the teacher, the teacher asks you to do the questions, you must do it, no matter how much, stay up late to do the meeting
Third, adjust one's own state to study, if you have no interest, you must cultivate interest and learn
Fourth, junior high school chemistry requires you to memorize some chemical equations, the required chemical equations, write them down several times, and then the properties of some elements, to remember, because each element has its own characteristics
Fifth, calculate the quality and other chemical calculation questions, practice more • Ask the teacher if you don't know how to experiment There are only a few types of experiments, review it, it's nothing, it's very simple

Anonymous users2024-02-04There are many ways to review, you can first review the unit, supplement the missing knowledge points, and then review them specially, such as basic concepts, basic principles, knowledge of elemental compounds, chemical experiments, and chemical calculations. Finally, carry out a comprehensive review, do some comprehensive questions, or mock papers, etc., as for how to review well, you have to according to your actual situation, if the foundation is good, you can directly enter the comprehensive exercise.

Anonymous users2024-02-03It's a good choice to build a set of mistakes, I chose college, but I think back to my junior high school learning methods, it's still okay, it's really good, because junior high school, including high school, is also simple and not so simple, and there are very few real things. When I was in junior high school, physics and chemistry were always the first in the whole school, because of the good method.

1. Write carefully.
Chinese is actually a subject that pays great attention to the neatness of the volume, especially in the scoring of composition, good writing can improve their own paper score, we must learn to develop a good Chinese writing habits, only serious writing will make our volume look neat and beautiful. >>>More
Strong shoulders today, my shoulders are also scum, just do it.
How to guide children to take the initiative to learn.
Biological knowledge is relatively trivial, and some teachers say that if they have memorized textbook knowledge, there is no problem with the basic college entrance examination. However, from the actual situation, there are still a lot of error-prone and easy-to-mix knowledge in biology, so it is still necessary to memorize textbook knowledge on the basis of understanding, and on this basis, master the skills of biology answering, and be able to quote the original words of the textbook in the process of answering questions. >>>More
Chemistry laboratory teaching blindness is an important means for students to obtain chemical knowledge and test chemical knowledge in chemistry teaching, which can provide perceptual understanding materials for students to form basic concepts and basic theories of chemistry, and can stimulate students' interest in learning. This year, with the great attention of the school leaders and the joint efforts of all chemistry teachers, some new progress has been made in chemistry laboratory teaching, which are summarized as follows: (1) Students' interest in learning chemistry has been stimulated, and students' initiative and enthusiasm in learning chemistry have been continuously improved.
