The activity of children's personal experience is to let children experience, comprehend, think and create by themselves through the materials provided by teachers, to materialize the scientific knowledge contained into various things that can be seen, touched and moved, to provide independent, operable and creative activity space for children, and to create a dynamic, comprehensive and open environment for children's scientific inquiry activities. This activity can not only exercise children's bodies, but also develop their intelligence. In the process of playing "stepping on the shadow", children can further understand the relationship between light and shadow. And through innovative gameplay, cultivate children's innovative consciousness and divergent thinking. Through games, let children practice running in a certain range, enhance their running ability, and initially cultivate their dodge ability during running.
