In this paper, we report a case study of project-based learning (PBL). PBL aims to allow students to experience collaboration across disciplines. The class comprised several teams, each of which consisted of students belonging to different departments. First, the students learned biomimetics prior to PBL and attempted to develop new commercial goods with the knowledge gained. The teams could make full use of the university’s facilities, such as 3D printers, to produce objects precisely. The students’ final results included the development of a propeller for hydropower or a drone. The students evaluated themselves using a rubric that we specifically developed for the class. The evaluation confirmed that the students became aware of the need and importance of teamwork.
