Abstract Taking the chemical reaction principle of water purification by alum as an example,this paper focused on analyzing the seven teaching connections in "chemistry 1" for high school,and then briefly introduced the teaching connection in two elective modules "Chemistry and Life" and "Principle of Chemical Reaction". Using mind map,model diagram,concept map,flow chart and other graphic thinking teaching methods,we could carry out knowledge linking teaching,which was helpful to strengthen students' subject understanding ability and cultivate their chemical core literacy.
