Abstract The project focuses on “recycling and utilization of scrap iron”, through four project tasks: clarifying project tasks, designing the conversion path of scrap iron, optimizing scrap iron recycling plans, and displaying recycling results, completes a special review of “common acids, alkalis, and salts”, and constructes a knowledge network of acids, alkalis, and salts, and a general model of material recycling and utilization, so as to penetrate disciplinary concepts such as element view, particle view, and transformation view, and develop key abilities like designing and evaluating experimental plans, exploring and innovating experiments, reasoning evidence and cognizing models.
