以海洋永續為核心的推廣教育企劃，將海洋環境教育轉化為可視、可觸、可實踐的學習體驗，喚起大眾對海洋生態的重視，使環保行動成為守護海洋持續推動的力量。

「溯」意指追溯與探索，以「行動中的永續教育」為概念設計一套永續海洋推廣套組並實際與青草國小合作。整體包含三本手冊及海廢實驗試片，用以探討海廢問題之根源，完整呈現海洋廢棄物的認知、再製應用與教學實踐紀錄。設計上以層層海浪的視覺意象貫穿，呈現海洋的流動性與海廢漂流軌跡，外盒採用回收海廢與再生材料製作，凸顯資源循環使用的實踐性。

「海廢圖鑑」透過抽拉式裝幀設計，模擬海廢隨波漂流的視覺效果，引導使用者以「翻閱」連結「撿起」海廢的意象，加深對海洋污染及可行動性的直觀感受。「實驗手冊」以回收魚繩線圈裝釘，透過各種海廢實驗試片呈現廢棄物轉化為可再利用材料的過程紀錄，激發學習者的創新思維。「教學紀錄」則收錄海洋教育的推廣歷程，藉由波浪形狀頁尾露出各頁內容，讓翻閱者感受環境行動的層層深化，並以回收魚繩縫製裝幀象徵海廢回收與再生的連結。

透過這套教具，讓教師更方便在教學中執行海洋永續實踐及資源循環使用教學，並將影響力延伸至家庭與社區，提升民眾對海洋環境的關注與行動。

Ocean Sustainability

“Trace” means to trace and explore, and ‘Sustainable Education in Action’ is used to design a sustainable marine promotion kit. It contains three manuals and an experimental film on sea waste. The design uses the visual imagery of waves to present the flow of the ocean and the trajectory of sea waste.
The pull-out design of the “Sea Waste Picture Book” simulates the visual image of sea waste drifting along with the waves, and the imagery of “flipping through” and “picking up” sea waste deepens the feeling of marine pollution. The “Experiment Manual” is a record of the process of converting waste into reusable materials by using recycled fishing rope and coil binding to stimulate learners' innovative thinking. The “Teaching Record” records the promotion of marine education, revealing the contents of each page through the wavy endpapers, allowing readers to feel the deepening of environmental action, and using recycled fish rope to symbolize the link between recycling and reclamation of sea waste. The outer box is made of recycled sea waste and reclaimed materials, emphasizing the practicality of resource recycling.
