Abstract By means of questionnaire, this paper analyzes the problems existing in the teaching of “water purification”: the students' cognitive level is shallow, it is difficult to understand the practice and connotation of water purification; the teachers' cognitive level is not enough to realize the value and significance of water purification. It is suggested that the history of the change of “water civilization” should be integrated into the teaching process, and the students should be helped to fully understand the purification process of water and truly appreciate the value of the chemistry subject through the activities of “seeing, moving, doing and tasting”, understanding the meaning of “green water and green mountains are mountains of gold and silver”.
