This article describes an interdisciplinary, activity-based lesson plan implemented in a third/fourth-grade classroom. During these activities, students use musical concepts to think about, illustrate, and discuss animal behavior, and they use scientific concepts to motivate musical composition and performance. The lesson ends with small group performances that allow the students to apply their knowledge to a new situation. These activities require no specific background knowledge about birds or music on the part of the students. A classroom teacher familiar with basic musical concepts can teach this unit alone or collaborate with a music teacher and/or science specialist. In addition to science standards, these activities also include the arts education standards of music composition and performance and understanding relationships between music and disciplines outside the arts (CNAEA 1994).
