In the first semester of the 111th school year, Yushan Junior High School led all seventh-grade students to go to communities in the school district for day study, where they learned about old houses and local culture, and discussed community transformation issues. However, through students' observations, they asked why there was so much garbage in the community. Based on the students' desire to change the community environment, and in response to the three aspects of independent action, social participation, and communication and interaction in the 108 curriculum, the "Sustainable Environment" was developed. "Aesthetic Action" cross-disciplinary curriculum plan connects reading, English, society, and art fields with environmental issues, allowing students to understand environmental sustainability, marine garbage issues, and plastic reduction awareness through cross-disciplinary courses, combined with outdoor reading, Street cleaning activities and creative sharing use practical exploration to introduce experience and empathy from affection, and then try to change their own living habits, and lead students to publicly promote the concept of environmental protection and plastic reduction inside and outside the school, so that students can do their best for the environment through practical actions.
