Abstract To explore the rational use of iron fertilizer as the theme, carry out the teaching of “iron and its compounds” in high school chemistry. By completing the three sub-tasks of “determining the main components of iron fertilizer”, “checking whether iron fertilizer is metamorphic” and “rational use of iron fertilizer”, students learn the transformation and inspection methods of different valence iron element compounds, forming the thinking of exploring the substance properties from the two perspectives of elemental valence state and substance category. It has preliminarily cultivated experimental inquiry ability, improved innovation consciousness, and developed model cognitive literacy based on the “valence-classification two-dimensional model of iron and its compound”. Students have gained real and novel, hands-on practice, group cooperation, exchange and display of achievement experience, the production of iron fertilizer reasonable use manual reflects the essential characteristics of project-based teaching, to achieve visibility, sharing, communication of learning results.
