Calculate weight on different planets using gravity data with exciting comparisons that let pupils discover how heavy (or wonderfully light!) they’d be on Mars, Jupiter or the Moon.

Explain how the Sun’s gravity creates stable orbits using clear modelling that shows planets constantly “falling around” the Sun rather than into it.

Describe centripetal force and why orbits are ellipses through simple demonstrations that make complex space physics feel accessible, visual and memorable.

Link orbital speed to a planet’s distance from the Sun so pupils understand why Mercury races around the Sun while Neptune drifts through the darkness at a slow, majestic pace.

Designed to be visually rich, easy to teach, and packed with wow‑factor space moments, this lesson turns orbital mechanics into an exciting, curiosity‑fuelled adventure your pupils will love.
