Geography serves as a key vehicle for science education. Using "Space Exploration" as a case, this paper proposes strategies for integrating science education into junior high geography across instructional design, implementation, and evaluation: integrating knowledge transmission with competency cultivation, linking problem-driven learning with inquirybased practice, and connecting knowledge, skills, and emotional values. Accordingly, it constructs a dual-competency enhancement design, an inquiry-based implementation pathway, and a data-driven evaluation framework, off ering a reference for implementing science education in junior high geography.
