lessonfieldWhat they’re learning
Your child is learning about the Sun, planets, moons, and other objects in the solar system, including scale, motion, and the difference between rotation and revolution.
Explain it to my child
Earth rotates once about every day, causing day and night. Earth also revolves around the Sun over about one year.
Try it together
Use a lamp as the Sun and a ball as Earth. Rotate the ball to model day/night, then move it around the lamp to model revolution. Keep the model’s limits explicit: distances and sizes are not to scale.
Practice
- What causes day and night?
- What does revolution mean?
- What object is at the centre of our solar system?
- Does the Moon make its own visible light?
- Why are scale models of the solar system challenging?
Check understanding
- Can your child distinguish rotation from revolution?
- Can they explain one limitation of a physical solar-system model?
Parent answer guide
- Earth’s rotation
- Orbiting around another object
- The Sun
- No; it reflects sunlight
- Real sizes and distances differ enormously
