Lesson Details
Key learning points
- The Sun is the centre of the solar system
- Earth, and other planets in the solar system, move around or orbit the Sun in an anticlockwise direction
- It takes different planets different amounts of time to orbit the Sun, depending on their distance from the Sun
- It takes 365 1/4 days, or one year, for Earth to complete one orbit of the Sun
Common misconception
Earth lies at the centre of the solar system, with the Sun and planets orbiting around it.
Provide opportunities for the children to explore both diagrams and 3D models of the solar system which clearly show the Sun and planets.
