Alternative and renewable fuels (biofuels, hydrogen, etc.) in school chemistry: an ecological context-based approach

Анотація

The growing global demand for sustainable energy solutions necessitates the integration of environmental education into science curricula. This study explores the methodological foundations for presenting alternative and renewable fuels—such as biofuels and hydrogen—within school chemistry through an ecological context-based approach. The paper emphasizes how chemical concepts related to combustion, energy changes, oxidation–reduction reactions, and environmental impact can be taught using real-world sustainability issues. A model for integrating renewable fuel topics into secondary chemistry lessons is proposed, linking theoretical knowledge with ecological awareness and responsible decision-making. The approach enhances students’ scientific literacy, systems thinking, and understanding of green chemistry principles. The findings suggest that contextualized instruction improves conceptual understanding while fostering environmental responsibility.
