Chemistry is a natural science based on experiments, Mendeleev.
The periodic table of chemical elements proposed.
It has greatly promoted the development of chemical mess pure grinding. Nowadays, many people call chemistry the "central science" because chemistry is at the heart of some scientific disciplines, such as materials science and nanotechnology.
Biochemistry, etc.

The five dimensions of chemistry core literacy are: "macro identification and micro analysis", "change concept and balanced thinking", "evidence reasoning and model cognition", "science and innovation consciousness", and "scientific spirit and social responsibility".
Literacy 1: Macro identification and micro analysis.
Able to recognize the diversity of substances from different levels and classify them.
Literacy 2: Changing Perceptions and Balancing Thoughts.
Be able to recognize that matter is moving and changing, and know that chemical changes require certain conditions and follow certain laws.
Literacy 3: Evidence Reasoning and Model Cognition.
Be evidence-aware and be able to make possible hypotheses about the composition, structure and changes of matter based on evidence.
Literacy 4: Science** and innovative awareness.
Knowing Science** is the practice of scientific interpretation and discovery, creation and application of science.
Literacy 5: Scientific spirit and social responsibility.
Have a rigorous and realistic scientific attitude, and have the consciousness of exploring the unknown and advocating truth.
Chemistry is a kind of natural science, mainly at the molecular and atomic levels, studying the composition, properties, structure and change laws of matter, and creating new substances (the essence is molecules that do not exist in nature).
The world is made up of matter, and there are two main forms of change: chemical change and physical change.
Different from particle physics and nuclear physics, which study smaller scales, chemistry studies the material structure of atoms, molecules, ions (clusters) and the interaction between chemical bonds and intermolecular forces, and the scale in which it is located is the closest to the macroscopic in the microscopic world.
Therefore, their natural laws are also most closely related to the physical and chemical properties of substances and materials in the macrocosm of human existence.
As an important bridge between the microscopic and macroscopic material worlds, chemistry is one of the main methods and means for human beings to understand and transform the material world.

Regardless of junior and senior high schools, the four core literacies are political identity, scientific spirit, awareness of the rule of law, and public participation.
Political identity: a sense of belonging that people have emotionally and consciously in their social and political life.
It is closely related to people's mental activities. When people live in a certain society, they always have to determine their identity in a certain social connection.
Scientific spirit: refers to the important form of science to realize its social and cultural functions. One of the main elements of scientific culture. It includes the fine traditions, cognitive methods, behavioral norms and value orientations formed by the development of natural sciences.
Awareness of the rule of law: It is people's heartfelt recognition, advocacy, observance and obedience to the law.
Public participation: It is the citizens in the representative system.
Participation in voting and election activities in politics, that is, the process of public participation in the election of representative institutions and personnel, is an important indicator of modern democratic politics and an important responsibility of citizens in modern society.
The political science community has not always agreed on the object of political science research, and many different opinions have been put forward, which can be divided into two categories:
One group advocates that the object of study of political science is political phenomena or political relations. It is believed that political science is the science of studying various political relations in society, the science of studying the laws of social politics and its development, or the science of studying the laws of the development of various political forces in society. The other group argues that the object of study of political science is the state, or various political phenomena and political relations centered on the state.
The above information refers to the encyclopedia - political science.
