This article presents a project, Shapes of Water, funded by the Finnish Cultural Foundation, which gave music education students the opportunity to compose children's songs about climate change with the help of artists from two fields (contemporary circus and music) and a scientist (chemistry). The article outlines the ways in which the composing project challenged students' attitudes toward composing as a method for educating children about climate change, and brings together the experiences of the artists and scientist during the project. Finally, three focus areas are presented with recommendations for a sustainable eco-socially oriented approach to music education.
