The big idea
Earth, the Moon and the Sun form a moving system connected by gravity and light.
Earth orbits the Sun while the Moon orbits Earth, and all three rotate. Their changing geometry creates phases and occasional eclipses.
◉
HOW SCIENTISTS KNOW
Regular orbital predictions, tides, shadows and spacecraft measurements reveal the system.

!A COMMON WRONG MODEL
The Earth-Moon-Sun System is only a name or picture to memorize.
✓REBUILD IT WITH EVIDENCE
Connect the earth-moon-sun system 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
Use a ball as the Moon, a larger ball as Earth and a stationary lamp as the Sun. Move one body at a time and label every simplified distance. Connect what you notice to the earth-moon-sun system using Earth and Moon.

Which statement best explains the earth-moon-sun system?
Choose the explanation that matches the evidence—not just the most familiar words.
Three things to remember
✓Earth, the Moon and the Sun form a moving system connected by gravity and light.
✓Earth orbits the Sun while the Moon orbits Earth, and all three rotate.
✓Evidence matters: regular orbital predictions, tides, shadows and spacecraft measurements reveal the system.
