The role of history lesson History lesson is to cultivate students' methods and abilities to look at problems from a historical perspective by telling students about historical events, historical figures, famous battles, prosperous times and governing the world, terms and agreements, the rise and fall of countries in history, etc. It is an important course to be learned from primary school to junior high school until high school.

Chemistry is a subject in middle school. Schools in some European countries began to set up in the 17th and 18th centuries. The official opening of China Middle School began in 192 with the Constitution of the King James Middle School, which stipulated that it should be opened in the third and fourth school year. In 194, the "Regulations of Playing Middle School" stipulated that it should be opened in the fifth school year of middle school. Since 1922, middle schools have been divided into junior high school and senior high school, and the content of this course has been included in junior high school natural science and senior high school science introduction, with 6 credits each. Since 1928, this course has been set up in junior and senior high schools. After the founding of the People's Republic of China, it was still set up in junior high school and senior high school respectively, with junior high school having one academic year and senior high school having three academic years. The teaching content of junior high school includes the basic concepts of chemistry, several most important elements, the most basic chemical theories and laws and chemical terms. The teaching content of senior high school includes more than a dozen most important chemical elements, important organic compounds and important basic theories. This is a subject based on experiments. Chemical experiments are divided into demonstration experiments, in-class experiments (or experiments while talking), students' experiments and experimental exercises. Junior high school and senior high school require to cultivate students' chemical experiment skills and calculation skills, attach importance to the education of scientific attitude and methods, pay attention to cultivate students' innovative spirit, stimulate students' interest in learning, and initially understand the development trend of chemistry.

Physics is a subject in middle school. Schools in some European countries have been set up since the 17th and 18th centuries. Tell the basic knowledge of physics according to the needs of society and students' understanding level. The formal opening of China Middle School began with the Constitution of the King James School promulgated in 192. It is stipulated that the middle school is a four-year system, and physics classes are set up in the first and second academic years. After the implementation of the new academic system in 1922, the number of years and hours set for each grade changed. After the founding of the People's Republic of China, physics in middle schools was changed to five years' continuous study from Grade Two to Grade Three, and the teaching hours were also increased. Its teaching objectives are different in different periods.
