Art is an important activity in society and culture. It not only has its own development process, characteristics and values, but also plays an intermediary and catalyst role in different activities in various fields. In the ever-changing context of globalization, cross-field abilities have become an important concept in education reforms in various countries. The cross-disciplinary aesthetic education achievements of the 109th school year of the real primary school are integrated into the ocean education issues, with the ocean as the center, changing thinking, through the creation of anthropomorphic children's poems, the visual presentation of animated frames, students reciting poems, and the music teacher's life sound effects to create ideas , allowing students to immerse themselves in the course and pay attention to issues such as ocean pollution and overfishing. It is hoped that one day, the Dragon Palace under the sea will regain its vigorous vitality, and the heart of the ocean will no longer shed tears secretly, and will happily sing the beautiful songs of the ocean. We sincerely hope that Taiwan, surrounded by the sea, can stand firm and survive sustainably in the beautiful roaring ocean for generations to come.
