mathematics
Mathematics is a basic subject, which is the foundation of other science disciplines. High school mathematics mainly includes elementary mathematics, analytic geometry, mathematical analysis, number theory and so on. Elementary mathematics mainly includes algebra, geometry and trigonometric functions. Analytic geometry mainly introduces the equation, position relation and intersection relation of plane, space straight line, plane and space curve. Mathematical analysis mainly introduces functions, limits, derivatives, calculus and so on. Number theory mainly introduces integers, prime numbers, congruences, algebraic numbers, number fields and so on.
physics
Physics is a basic subject to explore natural laws and phenomena. Physics in senior high school mainly includes mechanics, heat, electricity, optics and atomic physics. Mechanics mainly introduces kinematics, dynamics and statics. Thermodynamics mainly introduces the basic concepts of thermodynamics, the first law of thermodynamics, the second law of thermodynamics and so on. Electricity mainly introduces electric field, potential, capacitance, current, electromagnetic induction and so on. Optics mainly introduces the wave-particle nature of light, the reflection, refraction, interference and diffraction of light. Atomic physics mainly introduces the properties of atoms and molecules, nuclear physics, quantum mechanics and so on.
chemistry
Chemistry is a basic subject to study the nature, structure, changes and laws of matter. Senior high school chemistry mainly includes inorganic chemistry, organic chemistry and physical chemistry. Inorganic chemistry mainly introduces the periodic law of elements, chemical bonds and chemical reactions. Organic chemistry mainly introduces the basic structure, properties and reactions of organic matter. Physical chemistry mainly introduces basic concepts such as physical chemistry, chemical equilibrium and chemical thermodynamics.
biology
Biology is a basic subject to study life phenomena and the structure, function, development and evolution of organisms. Biology in senior high school mainly includes cell biology, biomolecules, genetics, ecology and so on. Cell biology mainly introduces the structure and function of cells, cell division, biofilm, cell differentiation and distribution. Biomolecules mainly introduce the structure and function of biomacromolecules, and the synthesis and metabolism of protein. Genetics mainly introduces the structure and function of genes, genetic laws, genetic engineering and so on. Ecology mainly introduces the composition and function of ecosystem, ecological environment protection, biodiversity and so on.
In a word, high school science refers to the general science courses in high school, including mathematics, physics, chemistry and biology, which plays an important role in cultivating students' scientific literacy and improving their scientific thinking ability.
