According to its vertical structure, the goals of preschool children's science education can generally be divided into four levels, namely, the overall goals, unit goals and activity goals of preschool children's science education.

While instructing children to observe things, teachers should teach children some basic observation methods purposefully and in a planned way according to the characteristics of the observed objects. In the pre-school education stage, there are mainly several observation methods, such as learning order observation and typical characteristic observation.

The development trend of American children's science education is to cultivate children's scientific learning methods, not to force them to lose them. Cultivate children's correct view of science and establish moral norms for using science.

The education system in the United States is very flexible, and the government only gives general guidance on policy orientation, without asking too much about the methods used by schools to teach students.

Main advantages:

Emphasize the role of preschool children's own interests, and let preschool children observe, understand and know the surrounding environment according to their own interests. Therefore, the individual scientific inquiry activity of preschool children is one of the important methods.

In this process, teachers only give a small amount of guidance to cultivate and stimulate the interest of preschool children, accompanied by a small number of planned group and collective exploration activities. Pay attention to the creation of environment and the preparation of various experimental materials, and provide preschool children with sufficient opportunities to observe and contact with nature.
