利用生活资源开展绿色化学实践教学研究——以初中化学《水的净化》一课为例

Research on Practical Teaching of Green Chemistry Using Life Resources—Taking the Lesson “Water Purification” in Junior High School Chemistry as an Example

摘要: 初中阶段是塑造个人价值观和世界观的黄金时期，在此阶段渗透绿色化学理念，对培养学生的可持续发展观至关重要。为了提升学生对绿色化学的认知，以人教版九年级化学《水的净化》为例，探索如何利用商洛市丹江水等本土生活资源开展绿色化学实践教学。通过创设真实情境、以生活物品替代实验器材、引导学生制作简易净水装置等策略，将“预防污染”及“循环利用”等绿色化学原则具象化。实践表明，该模式不仅能提升学生的实验技能与学习兴趣，更有助于培养其环保意识与社会责任感，为在初中化学教学中践行绿色化学理念提供可借鉴的路径。

Abstract: The junior high school period is a critical stage for shaping personal values and worldview. Integrating green chemistry concepts during this phase is essential for cultivating students’ awareness of sustainable development. To enhance students’ understanding of green chemistry, this study explores practical teaching strategies using local life resources, such as water from the Danjiang River in Shangluo City, within the lesson “Water Purification” from the ninth-grade chemistry curriculum of the People’s Education Press. By creating authentic contexts, replacing conventional experimental equipment with everyday items, and guiding students to construct simple water purification devices, principles of green chemistry such as “pollution prevention” and “recycling” are concretized. Practice demonstrates that this approach not only improves students’ experimental skills and learning motivation but also fosters their environmental awareness and social responsibility, providing a referential pathway for implementing green chemistry concepts in junior high school chemistry education.
