Begin the lesson by introducing the concept of Earth's orbit and its revolution around the Sun. Use a globe and a lamp to demonstrate how the Earth moves in its orbit and how this affects the seasons.
Go to the LessonLearning Objectives
- Understand the concept of Earth's orbit and its revolution around the Sun.
- Explain how Earth's axial tilt affects the change in seasons.
- Describe the speed of Earth's orbit and the time taken to complete one revolution.
- Identify the reasons for the occurrence of leap years and their significance.
Introduction and Hook
Engage students with a thought-provoking question: 'Why do we have leap years?' This will set the stage for understanding the Earth's revolution and its impact on our calendar.
Direct Instruction
Explain the concept of Earth's axial tilt and its role in the changing seasons. Use diagrams to show how the tilt affects sunlight distribution across the hemispheres.
Discuss the speed of Earth's orbit and the time taken to complete one revolution. Highlight the significance of the 365.24-day year and the need for leap years.
Guided Exploration
Watch the video 'Movements of the Earth – Quiz Edition' to reinforce understanding of Earth's rotation, revolution, and axial tilt. The video includes a quiz to test comprehension.
Facilitate a discussion on how Earth's movements affect our daily lives, such as day and night cycles and seasonal changes.
Hands-On Activity
Independent Practice
Check for Understanding
Conduct a class discussion to review key concepts, such as the causes of seasons and the significance of leap years. Ask students to explain these concepts in their own words.
Review and Reflection
Have students complete a reflection journal entry on what they learned about Earth's revolution and its effects. Encourage them to include any questions they still have.
Assessment and Extension
Use the 'Space' assessment to evaluate students' understanding of space-related concepts, including Earth's movements and the solar system.
