There are many ways and tricks to learn chemistry in junior high school, and here are some specific suggestions:
1. Pay attention to basic knowledge: junior high school chemistry is the starting point of chemistry learning, and you must master the basic knowledge, such as element valency, chemical formula, chemical equation, etc. These fundamentals are the key to solving the problem. In particular, the concept of valency, which is the cornerstone of the chemical edifice, only by truly mastering the valency, can we correctly write chemical formulas, chemical equations, etc. It is compulsory for students to memorize the valency of common elements, master the valency of the same element in different compounds, and correct the chemical formula of common compounds according to the valency.
2. Do more exercises: If you want to learn chemistry well, a certain amount of exercises is essential. By doing questions, you can deepen your understanding of the knowledge points and improve your problem-solving ability.
3. Be good at summarizing and summarizing: In the learning process, we should be good at summarizing and connecting knowledge points to form a knowledge network. This allows you to be more efficient when reviewing and deepen your understanding of the knowledge. If you can connect the outermost electron number of atoms, the valency of the elements, and the chemical formula to form a knowledge system, you can deepen your understanding and memory of the chemical system.
4. Pay attention to experiments: Chemistry is an experiment-based discipline, through which you can deepen your understanding of knowledge points and cultivate your ability to operate experiments. In the experiment, we should pay attention to observation, record, think positively, and improve our observation ability and hands-on ability.
5. Cultivate interest in learning: Interest is the best teacher. If you have a strong interest in chemistry, you will be more self-motivated, and you will be willing to do it even if the salary is not high. Conversely, if you don't have an interest in chemistry, no amount of high salary will motivate you to complete it.
6. Communicate with classmates: Communicating learning experiences and experiences with classmates can help you find out your shortcomings in learning, and learn from the advantages and experiences of others to improve your learning effect.
7. Regular review: Human memory has a forgetting curve, in order to maintain the memory of knowledge, we must review it regularly. When reviewing, it is necessary to connect the relevant knowledge points to form a knowledge network, so that the knowledge can be extracted at any time when it is necessary to apply it.
In short, learning junior high school chemistry well requires a lot of hard work and practice. Hopefully, the above suggestions will help you improve your learning and achieve better results.
