Begin the lesson by discussing the daily cycle of day and night. Ask students to share their observations about the Sun's position at different times of the day.

Rotation of the Earth
Learning Objectives
- Understand that the Earth's rotation on its axis causes the apparent movement of the Sun across the sky.
- Explain how the Earth's 23.5-degree axial tilt affects the cycle of day and night.
- Describe how the rotation of the Earth influences the length and direction of shadows during the day.
- Identify that it takes 24 hours for the Earth to complete one full rotation on its axis.
Introduction and Hook
Introduce the concept of Earth's rotation using a globe and a flashlight to simulate the Sun. Demonstrate how the Earth's rotation causes day and night.
Direct Instruction
Explain the Earth's 23.5-degree axial tilt and how it affects the cycle of day and night. Use diagrams to illustrate the Earth's axis and rotation.
Watch the video 'Day and Night – The Rotation of the Earth' to reinforce the concept of Earth's rotation and its impact on daily life.
Guided Exploration
Engage students in a discussion about how the Earth's rotation influences the length and direction of shadows during the day.
Watch 'Day and Night Explained in One Minute' to provide a concise explanation of how Earth's rotation affects shadow patterns.
Hands-On Activity
Conduct the 'Modeling the Earth’s Rotation' activity where students use modeling clay and a flashlight to simulate day and night.
Independent Practice
Assign students to observe and record the length and direction of shadows at different times of the day over a week.
Use the 'Daily Shadow Patterns' assessment to help students analyze their observations and understand how the Sun's position affects shadows.
Check for Understanding
Ask students to explain how the Earth's rotation causes the apparent movement of the Sun across the sky.
Use questioning techniques to assess students' understanding of the Earth's axial tilt and its effects on day and night.
Review and Reflection
Review key concepts by watching 'Earth's Rotation – Day and Night' to reinforce understanding of the 24-hour rotation cycle.
Encourage students to reflect on what they have learned about the Earth's rotation and how it affects their daily lives.
Assessment and Extension
Administer the 'Space' assessment to evaluate students' understanding of space-related concepts, including Earth's rotation.
Try the Quiz
For further exploration, students can engage in the 'Earth’s Orbit and Seasons – Comprehension' assessment to connect Earth's rotation with seasonal changes.
