Four Seasons

Description
In this video, we demonstrate a Four Seasons table-top model to explain how Earth’s tilted axis and revolution around the Sun cause seasonal changes. This simple visual model helps students clearly understand why different seasons occur at different times of the year.
Learning Objectives

  • Understand what causes the four seasons.

  • Learn about Earth’s axial tilt (23.5°).

  • Understand Earth’s revolution around the Sun.

  • Observe how sunlight varies during different seasons.

  • Develop basic astronomy visualization skills.

    • Key Takeaways

    1. Seasons are caused by Earth’s tilt, not distance from the Sun.

    2. Earth completes one revolution in about 365 days.

    3. Different hemispheres receive different sunlight during the year.

    4. The table-top model makes seasonal changes easy to visualize.

    5. This model explains summer, winter, spring, and autumn clearly.
