Modeling the Difference Between Rotation and Revolution
Materials: ★☆☆ Easy to get from supermarket or hardware store
Difficulty: ★☆☆ Can be easily done by most teenagers
Safety: ★☆☆ Minimal safety procedures required
Categories: Astronomy and Space
Alternative titles: Teaching Rotation and Revolution
Summary
This activity helps students distinguish between rotation and revolution using models, body movement activities
Procedure
- Provide students with objects to model rotation (e.g., fidget spinner, coin) and ask guiding questions about movement and center points.
- Use body modeling: assign roles of Earth and Sun, and have “Earth” rotate on its axis and revolve around “Sun.” Add “Moon” for more complex modeling.
- Expand to a large group body model: multiple students form circles for Sun, Earth, and Moon, performing rotations and revolutions simultaneously.

Variations
- Add Moon phases by having a “Moon” rotate and revolve around “Earth.”
- Conduct activities outdoors for more space, or in a gym if weather prevents outdoor learning.
- Challenge students to model sunrise, sunset, noon, and midnight with rotations.
Safety Precautions
- Remind students to move slowly during body modeling to prevent falls or collisions.
- Set clear behavior expectations before starting physical modeling activities.
- Use sturdy, safe classroom materials (e.g., dull pencils for foam balls, not sharp objects).
Questions to Consider
- What is the difference between rotation and revolution?
- How does Earth’s rotation cause day and night?
- How does Earth’s revolution cause seasons?
- Why is it important to know the difference between “axis” and “orbit”?
- How is the Moon’s movement similar to and different from Earth’s?
