The big idea
The Moon does not make visible light; it reflects sunlight.
At any moment, sunlight illuminates half of the Moon except during a lunar eclipse. The bright part we see depends on viewing geometry.

HOW SCIENTISTS KNOW
The Moon's lighting direction always matches the Sun's direction, and lunar rocks reflect measured sunlight.

!A COMMON WRONG MODEL
The Moon makes its own visible light.
✓REBUILD IT WITH EVIDENCE
Trace sunlight to the Moon and reflected light toward Earth.
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 moon reflects sunlight using reflection and sunlight.
