What are the difficulties in junior high school physics and chemistry? Thank you for your advice

Physics: Electricity and Mechanics. The focus is on students' experimental ability and calculation ability. Understand how to use the experimental tools in the book, the experiments mentioned in the book, and learn to use formulas to solve problems.

Chemistry: 1. Memorize chemical terms. Includes: Element Symbols, Chemical Formulas, Ion Symbols, Valency, Chemical Equations. The difficulty with it is that the majority can understand it, but the minority can't, and can only forcibly memorize it.

2. Methods and skills of problem solving. This difficulty can only be solved by doing more questions.

You just need to make sure that you concentrate on listening carefully during class, strike while the iron is hot after class, and do more related exercises, it's OK, it's not difficult at all, the important thing is whether you stick to it, I hope you can quickly apply it to learning, physics, chemistry is not difficult, see if you can learn the method, I wish you to quickly improve your physics and chemistry grades.

Chemistry attention is not a pure science, and it takes a lot of memory to understand, and the teacher will give the valence of the periodic table or something. Even if you don't understand it, you will do it if you have memorized it, and memory is really important. Actually, it's not that difficult.

Do more questions in physics, and the electricity part is more difficult, practice more, according to the question type. And then there's the innovation question, which has to do with interest or something. The force part is more difficult to understand, but the questions are not difficult.

The men are not afraid of physics and chemistry, and junior high school is relatively simple, as long as the main teacher can understand it.

Physics and chemistry in junior high schools in Zhejiang Province are grouped into one subject - science.

The Zhejiang version is only science, science includes physics, chemistry, biology, geography, which is equivalent to the merger of the four disciplines, the content is basically the same as other versions, and the knowledge points of the four disciplines are staggered.

The Zhejiang version of the textbook has a discipline in one chapter and one knowledge point in one chapter. For example, the second unit is the understanding of microscopes and cells in biology, and the third chapter is the knowledge of geography.

Version used in science textbooks in Zhejiang Province:

There are Zhejiang Education Edition (Zhejiang Education Press) and China Normal University Edition (East China Normal University Press). The science textbooks in Ningbo City use the ECNU edition, and the science textbooks in other parts of Zhejiang Province use the Zhejiang Education Edition.

In junior high schools where there are physics, chemistry, and biology classes, biology classes begin in the first year (seventh grade), physics classes begin in the second (eighth grade), and chemistry classes begin in the third (ninth grade). Some of the learning content in the Chemistry and Biology courses overlap with each other. The nutrients in food are not only the learning content of biology, but also the learning content of chemistry.

In the Zhejiang version of junior high school science, there is physics in the first year of junior high school, and chemistry in the second semester of junior high school, such as chemical elements, valence, and chemical formulas. Students can't tell which content in junior high school science is chemistry and what is physics.

Except for Zhejiang Province, I don't know if there are some places where junior high schools do not have physics, chemistry, and biology classes, but there are science classes.

Physics and chemistry are classified as one subject in the junior high school of Jiang Province - science.

The Zhejiang version is only science, which contains physics, chemistry, biology, and geography, which is equivalent to merging the four disciplines, and the content is basically the same as other versions, and the knowledge points of the four disciplines are staggered.
