This document describes an interdisciplinary project for 5th grade students titled "Save the World!" involving natural sciences, social sciences, and music. The project aims to raise awareness about caring for the planet. It is divided into three sequences: 1) learning about ecosystems and the world, 2) the impact of human actions on the environment like pollution, and 3) what individual actions students can take to help the planet. The project uses activities like reading, discussion, and creating a song banner to teach students about these topics over the course of three classes.
