In the high school chemistry teaching, if we can give full play to the teaching effectiveness of chemistry experiment (that is, “the motivation of motivation”, “cognition”, “method”, “innovation” Moral Education, Aesthetic Education, “etc.) will help improve teaching effectiveness. First, to play ”interest motivation “ efficiency, to develop students interest in learning chemistry ”experimental interest " is divided into temporary interest and stable interest, it is from low to high, and students the level of thinking and cognitive development of the simultaneous development of fun .
