I want to ask how to study chemistry in the second year of high school, and I don t know anything

Chemistry is a fascinating subject. However, due to the characteristics of high school chemistry as "complicated, difficult, and chaotic", many students find it difficult to learn high school chemistry. So how can you learn chemistry in high school?

1. Listen carefully and take good notes.

Good notes are the condensation, supplementation and deepening of textbook knowledge, and the presentation and refinement of the thinking process.

Since the knowledge points of chemistry are numerous, fragmented and scattered, in addition to listening carefully and thinking positively, in addition to listening carefully and thinking positively, we should also write down the key and difficult knowledge of the teacher in our own words on the basis of understanding, so as to facilitate future review.

2. Review in a timely manner.

Revision is not just a simple review of knowledge, but considering the interconnection of old and new knowledge in one's own brain, and reorganizing it to form a new body of knowledge. Therefore, after class, it is necessary to review the content of the lecture in a timely manner, and do a good job of sorting out and summarizing the knowledge, so as to make the knowledge integrate and avoid the phenomenon of more and more chaos in learning. For example, if you learn about the bleaching properties of SO2 and chlorine water, you can compare them to find out the differences.

3. Learn to memorize.

Since there are many chemical knowledge points to memorize, it is difficult to memorize them if you rely on rote memorization, so you should learn to memorize them skillfully. The commonly used memorization methods in chemistry are: comparative method (often used for knowledge that is easily confused and interferes with each other.

The four similar concepts of isotope, allotrope, homologue, and isomer can be deepened and remembered through comparison. ), induction, song recipe memory, comprehension memory, and experimental memory.

Fourth, diligent practice.

Practice is an important way to understand, digest, and consolidate classroom knowledge. However, the practice should be targeted, not a sea of tactics, and should be aimed at mastering the basic methods and the rules of problem solving. In the process of problem solving, it is necessary to pay attention to multiple solutions and inductive summarization of one problem, so as to achieve the effect of doing one problem and one category.

For example, the techniques commonly used in chemical calculation include: conservation method, relational method, extreme value method, average value method, estimation method, difference method, etc.

5. Prepare a "mistake book".

The purpose of the questions is to develop abilities and find effective ways to find your weaknesses and deficiencies. Therefore, mistakes should be corrected and recorded. When recording, you should analyze the reasons for the error and the correct solution idea in detail, and do not simply write an answer.

At the same time, it is important to go through the review frequently so that you can avoid similar mistakes in the future.

6. Pay attention to chemical experiments.

Chemistry experiments can not only cultivate students' observation, thinking, hands-on and other abilities, but also deepen their knowledge and understanding of related knowledge, so we must pay attention to chemical experiments. When doing experiments, we should ask a few more whys, think about how to do it, why we do it, and what else can be done, so as to achieve the purpose of "knowing what it is and why it is true".

In addition, in order to study chemistry well, we should pay more attention to social hot issues and life problems related to chemistry, and be good at combining book knowledge with practice.

In short, as long as the learning method is correct, I believe that students will easily learn chemistry well.

In fact, the liberal arts you choose will not be too difficult to take in chemistry, it is very easy, the key is to listen carefully in class, follow the pace of the teacher, do your homework well, you have a lot of questions to say, you should ask the teacher and classmates in time, in that case, you will find that your chemistry is getting better day by day.

1. Physicochemical biology is a compulsory content, and all of them must be learned.

2. There is an academic proficiency test in the second year of high school, where liberal arts students take science, and science students take liberal arts, biology, physics, chemistry, politics, history, and geography.

3. The content is not very difficult, it is the foundation of the compulsory course, and basically you can pass it.

In the second year of high school, physical chemistry should not be; In the case of biology, if you pass the exam, you won't study it, and if you don't take the exam, you will have to study it in the first half of the semester.

Sophomore liberal arts students also have to study physics and chemistry, and they also take the monthly exam and the mid-term and final exams. However, for liberal arts students, it is not very important. The focus should still be on your liberal arts class, but it is recommended that you listen well in class as much as possible, and don't even know a little science knowledge in the future, which is not good.

You still have to learn in the second year of high school, and you have to learn liberal arts after completing the compulsory courses.

I still have to study in the second year of high school.

Because it is a compulsory course, all the content must be completed, and science students must also study liberal arts, and there will be an academic proficiency test in the second half of the second semester of high school, and only biology, physics, chemistry, politics, history, and geography will be examined.

The content is not very difficult, so the foundation in the compulsory course, some of which will be a little elective, as a liberal arts student, you can understand all the questions in the science content textbook, and there are also academic level test questions over the years, which are very important.

Good luck with your studies

ps: I don't know about Zhejiang, but there should be some compulsory electives in your textbooks, and the first half of the first semester of high school and the second semester of high school are almost all compulsory content, liberal arts students basically don't learn science electives, physics seems to be able to learn, we are like this, but elective physics is very simple, rest assured

Summary. For liberal arts students, studying chemistry can be challenging, but it's not impossible. Here are some suggestions to help you learn chemistry better:

1.Establish the basics: First, make sure you have some understanding of the basic concepts and principles of chemistry.

Make a reasonable study plan and follow the plan. Allocate time to different topics and chapters in order to learn all aspects of chemistry holistically. 3.

Do more practice: Chemistry is a very practical science, so it's important to do more practice. By doing exercises and analyzing past questions, you can consolidate your knowledge and improve your problem-solving skills.

4.Ask for help: If you have difficulties or difficult to understand concepts, you can seek help from your teacher or classmates.

They can provide you with answers and guidance to help you better understand chemistry.

Ask for help: If you have difficulties or difficult to understand concepts, you can seek help from your teacher or classmates. They can provide you with answers and guidance to help you better understand chemistry.

Attend tutorials or training sessions: If you don't feel like self-study is enough, consider attending a professional tutorial or training course. These courses often provide more detailed explanations and more opportunities for practice to deepen the understanding of chemistry concepts.

Use technology tools: Leverage technology tools such as chemistry simulation software, resources, and mobile apps to aid learning. These tools can provide you with a learning experience and hands-on opportunities.

Hope the above advice is helpful to you! Good luck in next year's baccalaureate!

Not yet, I'm taking online classes. Does the teacher have a question paper?

No, oh dear.
