This study applies the flow learning of Joseph Cornell to design two topics, “Secrets of Trees” and “Life Environment”. Also, it integrates environmental education into the course of Science and Life Technology and applies action research to solve related problems encountering in teaching. It explores what level the students have achieved in segmental ability index of environmental education and researchers’ professional knowledge and self-growth improved after those related curricula. Results of this study are: 1. Designing courses with flow learning enrich contents of environmental education. 2. Students achieve following objectives in this research’s teaching activities: (1) Growth of environmental awareness and sensibility (2) Growth of knowledge of environmental concepts (3) Improvement of environmental ethics value (4) Growth of environmental action skills (5) Participation of environmental action. 3. Researchers are allowed to apply action research to overcome obstacles and to recognize blind spots in teaching. It’s beneficial for researcher to use action research again in the future.
