This activity is the result of a school-university collaboration among four educators (two intermediate classroom teachers, a vice-principal/teacher, and a university-based teacher educator/researcher) who worked together to improve the quality of learning in the classroom. The educators combined their teaching expertise to plan and co-teach an integrated science and music unit in a grade 4 and a grade 4/5 class. In this six-part unit students rotate through sound exploratory centers and conduct investigations to learn how different factors such as the size, material, and contents of containers affect the behavior of sound. Students also design and make their own instruments.
