Earth’s Rotation – Day and Night

Learning Objectives

  • Understand that Earth rotates around an axis, causing day and night.
  • Identify that one rotation of Earth takes 24 hours, resulting in a regular cycle of day and night.
  • Describe how the side of Earth facing the sun experiences daytime, while the side facing away experiences nighttime.
  • Explain the concept of Earth's axis as an invisible line through the planet that it spins around.

Introduction and Hook

Begin with a captivating question: 'Have you ever wondered why we have day and night?' This question will engage students and set the stage for exploring Earth's rotation.
