What are the extracurricular review materials for physics, chemistry and biology in the third year o

To put it simply, it is a review material for science, you can buy it directly, such as Little Bear Books, which specializes in various teaching aids for high school, and also has review materials for the college entrance examination, I have bought it, and it is quite easy to use.

Biology: The learning of biology should not be based on the learning method of mathematics, physics and chemistry, and the learning method should be similar to that of geography. There are not many knowledge points explained in a class of mathematics, physics and chemistry, and a key knowledge will be repeatedly trained in class.

There are a lot of knowledge points in a biology class, and it is not an exaggeration to say that every word the teacher says may be a test point. And the class time is tight, and I can't consolidate the practice in class. Therefore, the exercises after class must be done carefully, and if you don't understand, you should ask immediately.

The topic of biology is relatively comprehensive from the beginning, and a topic will involve many knowledge points. This kind of connection of knowledge points is what the teacher emphasizes or supplements in the classroom, and many students do not listen to the lecture and read the book by themselves, but they can't do the questions after reading the book. There are also students who only listen to what is in the textbook in class, and they don't listen to what is not in the textbook because they think it is not important.

These should all be avoided. Requirements and methods for learning biology lessons: 1

To learn biological knowledge, it is important to understand and think diligently. 2.It is necessary to attach importance to understanding the process and methods of scientific research, and conscientiously conduct observations and experiments.

3.It is necessary to attach importance to integrating theory with practice. Chemistry:

The main thing is to memorize some properties, to write equations and so on. Textual things, you can take a look at it and memorize it. The key to theoretical things is to understand, and if you understand it, you will be able to draw inferences from one another.

For example, in a chemical equation, in order to write a correct chemical equation, you must first write the chemical formula of each reactant and product, and in order to write the correct chemical formula, you must understand the valency. If you just rely on rote memorization, it is still easy to forget when it comes to the exam, and understanding is the most important thing. So you have to memorize more practice questions, such as multiple-choice questions, the teacher gives you some special properties to choose, so more practice can invisibly help you remember.

The effect of light memory is not good. The more you practice the nature of those special substances, the more you will remember. The big topic is reasoning, writing equations, and with a good foundation, you will not be afraid.

Physics: Mainly the understanding of concepts and formulas. For concepts, you must grasp them well, and doing more multiple-choice questions will help you grasp the understanding of concepts.

But you must take each question seriously and understand each option when you do it. Calculation questions are accurate formulas. So be especially aware of the meaning of the formula.

Practice more, the questions are actually many similar. In short, it is a process of accumulation, the more you know, the better you learn, so memorize more and choose your own method. Good luck with your studies!

High school science students have to study a total of 7 books in physics, namely:

1. In the first semester of high school, students will study Physics Compulsory 1 and Physics Compulsory 2 in the second semester.

2. In the second year of high school, students will study "Physics Elective 3-1" and "Physics Elective 3-2" in the first semester, and "Physics Elective 3-3", "Physics Elective 3-4" and "Physics Elective 3-5" in the second semester.

3. The third year of high school enters the college entrance examination for general review.

Summary. Send the original question to the teacher.

Direct import method.

Calcium chloride treatment.

Ampicillin.

Primer amplification validation.

Founded in 2003, Xueersi International Education Group is committed to providing high-quality extracurricular tutoring for children aged 3-18, and has become a brand of extracurricular tutoring for primary and secondary schools trusted by parents and students in Beijing and even across the country. Xueersi is in Beijing, Shanghai, Tianjin, Guangzhou, Shenzhen, Shenyang. and other cities have established branch campuses, and the branch schools and teaching points are wholly-owned direct sales models, and teachers are uniformly trained.

2. Simple learning network.

Simple Learning Network was founded in early 2007 by Beijing Simple Technology. Relying on the "CAT technology" developed by Peking University, Simple Learning Network is the first interactive online school in China. With first-class teachers and relying on national patent interactive classrooms, it has developed rapidly and risen rapidly, and has developed into the most professional online school in China and the leading personalized online school in China.

3. Beijing No. 4 Middle School Online School.

Beijing No. 4 Middle School Online School is a distance education institution of Beijing No. 4 Middle School. Beijing Sipiwang Middle School Online School provides distance learning tutoring for primary and secondary school students across the country, using advanced network information technology.

Provide an open learning platform and educational resources of Beijing No. 4 Middle School. Beijing No. 4 Middle School Online School carries out teaching that transcends time and space, highlights individuality, and independent learning, emphasizes the individualization and interactivity of learning, and builds the largest online learning community for basic education in China.

Parent evaluation of high school physics online course platform.

2. The simple learning network is particularly convenient to use, and the teachers are also very strong. It is a good choice for children who cannot receive face-to-face instruction.

3. I still have some understanding of Xueersi Online School, after all, I have tried out the class in the online school app, and I really feel that the teachers of Xueersi Online School are still quite good, after all, it is still almost the same as the school in reality, because there is an online class teacher, the effect is also very good, and the current reputation is also good.

High school science students have to learn 7 books on physics, which are:
