Life science holds that biology is a living object, and the primary problem of life education is to teach young people how to know life scientifically and reasonably. After chemical evolution produced primitive life, biological evolution began, and human life was the result of this evolution.
Macroscopically speaking, life is the movement form of protein and nucleic acid substances, and it is a special, advanced and complicated material movement form. Growth and development is the basic process of life, while metabolism is the most basic process of life and the basis of all other life phenomena. General life forms have some "purposeful" behaviors, while human beings, as advanced forms of life, have conscious and purposeful behaviors.
Carrying out life education is a necessary condition to promote the healthy growth of young students' body and mind. With the increasingly rich material life and complex social environment in modern society, the physiological maturity of young students is obviously ahead of schedule, which easily leads to the imbalance of physical, psychological and moral development.
