Earth's Rotation and Orbit Concepts

This lesson explores the relationship between Earth and the sun, focusing on the concepts of Earth's atmosphere, rotation, and orbit. It explains how these factors contribute to the day and night cycle and the importance of the sun for life on Earth. The lesson also covers the role of gravity in maintaining Earth's orbit around the sun and encourages students to reflect on the differences between rotation and orbit.
