The document outlines a lesson plan for a grade 3 music class where students will learn to create sounds using their bodies. They will form a "storm choir" by taking turns rubbing hands, snapping fingers, slapping thighs, and jumping. The teacher will explain that music can be made in many ways without traditional instruments. Students will watch a video of a "rain choir" and then practice the body movements together under the teacher's conducting. The goal is for students to understand they can be musical instruments and that collaboration is needed to make some sounds.
