The scientific principle means that in the process of designing and organizing preschool children's scientific education activities, the scientific education content selected for children must be objective, realistic and in line with the direction of scientific development, and the designed teaching methods must conform to the scientific laws and children's cognitive characteristics.

(2) Development principles

The principle of development means that in the process of designing and organizing preschool children's science education activities, on the one hand, it is required that the goals, contents, methods and means of science education should be continuously developed and improved with the development of science and people, on the other hand, it is also required that science education should promote children's all-round development.

(C) the principle of fun

The so-called fun principle means that the pre-school science education activities designed and organized should be lively and interesting, loved by children and entertaining.

(d) the principle of integration

The principle of integration means that when designing and organizing preschool science education activities, teachers should not only consider the science education activities themselves, but also infiltrate with other educational activities, and coordinate the use of various educational factors that are beneficial to children's science for systematic education.

(5) Principles of activities

The activity principle means that when designing and organizing preschool science education activities, we should respect children's dominant position and provide them with rich activity materials. Ensure enough time and space for activities, and let them actively explore in rich practical activities, so as to acquire scientific knowledge, develop scientific ability and cultivate scientific spirit.
