The big idea
Planets are worlds orbiting stars; the planets we see at night reflect sunlight rather than producing their own visible light.
Against the background stars, planets slowly change position, which inspired the ancient idea of wandering lights.
◉
HOW SCIENTISTS KNOW
Repeated position measurements and telescope observations reveal planetary orbits, phases and disks.

!A COMMON WRONG MODEL
Planets in the Night Sky is only a name or picture to memorize.
✓REBUILD IT WITH EVIDENCE
Connect planets in the night sky to the observable relationship, evidence and system described in the lesson.
A scientifically true sentence can still create a false picture. This repair makes the relationship visible.
Take learning into real life
Try it together
With an adult, observe one safe patch of sky for five minutes. Record time, direction, color and motion before offering an explanation. Never look at the Sun. Connect what you notice to planets in the night sky using planet and orbit.

Choose the explanation that matches the evidence—not just the most familiar words.
Three things to remember
✓Planets are worlds orbiting stars; the planets we see at night reflect sunlight rather than producing their own visible light.
✓Against the background stars, planets slowly change position, which inspired the ancient idea of wandering lights.
✓Evidence matters: repeated position measurements and telescope observations reveal planetary orbits, phases and disks.
