When to use it
Science teachers assign planet projects with it. In no-repeat mode the first eight students or groups each get a different world, and Start over brings them all back for the next set.
It makes a quick space quiz. After each spin, ask whether the planet is rocky or a giant, whether it has rings and roughly where it sits compared with Earth.
Kids who love space can use it at home to choose a bedtime fact to look up, a model to build or a planet to draw for the fridge.
Ideas
- Planet passport: spin, then write a pretend travel guide with the weather, the length of a day and what you would pack.
- Scale walk: spin a planet and pace out its distance from the Sun on a playground using a simple scale.
- Moon count: guess how many known moons the chosen planet has, then check NASA's page for the current number.
- Order challenge: spin three planets and line them up by size, then by distance from the Sun.
Variations
- Add Pluto, Ceres and the other dwarf planets for a longer wheel that covers more of the solar system.
- Keep only the four rocky inner planets or the four outer giants when a lesson focuses on one group.
- Pair the wheel with the team generator to split the class into eight planet teams before you spin.
Tips
- Look up current facts on NASA's site rather than an old textbook, since moon counts change as new ones are discovered.
- Use full screen on the classroom board so the planet name is easy to read from the back row.
- Share the link with families so children can keep exploring the same wheel after school.
