Abstract “Formation of solution” is a typical content of the diversity of substances in junior high school chemistry. Through three links of “making milk tea\|exploring milk tea\|tasting milk tea”, this paper enables students to design experiments, observe, compare, classify and reason by means of hand\|held digital experiments, model sketches and other means, understand solutions from multiple angles, and construct the relationship between the macro characteristics and micro essence of solutions. In real life situations, this paper changes experimental strategies and learning methods, completes challenging tasks, and gradually deepens the understanding and transfer application of the core knowledge of solution, comprehends the concept, method and value of discipline in “learning by doing” and “learning by using”.
