Abstract With “silver corrosion and silver restoration” as the project learning theme and real life situation as the carrier, the whole project learning content includes: chemical corrosion and electrochemical corrosion, factors affecting the size of the electromotive force of the primary battery, cathodic protection method of sacrificial anode, cathodic protection method of impressed current. Through a variety of experimental activities such as family small experiment, student group inquiry experiment, teacher demonstration experiment, etc., the teaching design idea and teaching practice process of “project-based learning to develop metal corrosion and protection” are presented.
