The big idea
Planetary rings are vast systems of countless orbiting particles, not solid platforms.
Particles range from dust to boulders and follow separate orbits; moons can shape gaps and edges.
◉
HOW SCIENTISTS KNOW
Spacecraft images, stellar occultations and particle measurements reveal ring structure.

!A COMMON WRONG MODEL
Planetary rings are solid disks.
✓REBUILD IT WITH EVIDENCE
Zoom in until the ring separates into many independently orbiting particles.
A scientifically true sentence can still create a false picture. This repair makes the relationship visible.
Take learning into real life
Try it together
Lay out a Sun card and eight planet cards in order. Add one label for rock, gas or ice and one warning that the distances are compressed. Connect what you notice to planetary rings using ring and particle.
