From a scientific point of view, because children put on green glasses, they explored, saw the unexpected world and felt the changes brought by green glasses. After the children felt the poetic atmosphere, I asked them to put on red, blue and purple glasses and go outside to have a look and feel the color changes of the world around them. Therefore, we can deeply understand and appreciate the "green world" depicted in the works, and connect the experience of the works with personal experience. Guide children to imitate poetry, adapt the word "green" in poetry into "red" and "blue", and finally connect the poems of various colors compiled by children in series to form a long poem of "colorful world".
Children are naturally interested in all novel things, and the changes in the world around them attract their attention. In this activity, children gained knowledge through observation. Observation can not only improve children's scientific inquiry ability, but also develop children's thinking and language expression ability. Comenius, a famous Czech educator, said: "A person's wisdom should come from observing the real things in the sky and underground. At the same time, the more he observes, the stronger his knowledge will be." .
