This project focuses on children, combining mountain cleanup activities with environmental education. Through visual communication design, it establishes a clear visual language and guidance system to transform abstract issues into understandable information and strengthen the connection between behavior and environmental impact. The team collaborates on research and analysis, visual design, and teaching aid development, making visuals not only convey messages but also a key medium for guiding participation and cultivating sustainability awareness. This work is specially designed for the Hutoushan Trail in Taoyuan, constructing a complete exploration equipment and process design. Through the interactive mechanism of "role-playing tasks" and "exploration maps," it guides children to internalize their on-site environmental discoveries into spontaneous thinking and creative expression.
