It outlines the core subject description, performance standards, essential topics to be taught, and how student learning will be assessed. The plan details the content and standards to be covered in each unit, including the origin and structure of Earth, Earth materials and processes, Earth processes, and the history of Earth. For each unit, it identifies the key learnings, assessments to evaluate understanding and higher-order thinking skills, and enabling strategies to develop those skills. The culminating performance standard requires students to devise plans for resource conservation and environmental protection.
