Abstract With the project theme of “exploring the composition of metal materials in drink cans”, this paper carries out a study project on “metal materials” among high school students. They are required to complete five explosive tasks based on the project, including “the corrosion resistance of the body and lid of Coke cans”, “the aluminum content in the can body, pure aluminum or aluminum alloy”, “whether Coke cans made of aluminum alloy body contains iron”, “differences in properties and compositions of iron alloys with different uses” and “the understanding of new alloys”. By doing so, students are expected to transform the study of aluminum alloy, ferroalloy and new alloys into continuous exploration and practice, form the core concept of “composition and structure determine performance, performance determines use”, develop the habit of communication and cooperation, and develop skills in critical thinking and problem-solving. Authentic and challenging task-driven teaching, independent and open-ended learning, as well as the process and diversified evaluation are the keys to its success.
