1, science. The content of preschool children's science education needs to be based on scientific theory and practical experience. Scientificity is the standard to judge whether things conform to things, phenomena and processes existing in time and space, and it is based on science rather than imagination.

2. Enlightenment. The teaching method of preschool children's science education should pay attention to heuristic teaching, encourage children to explore and practice independently, and cultivate their curiosity and exploration spirit. The enlightenment principle in preschool education means that preschool education should provide children with the most basic and introductory education and lay a preliminary foundation for their future study and development.
