Moon Shapes in the Night Sky
Age 7 · Astronomy
Sunlight shines on the Moon and lights up one side of it. We see only the lit part, so the Moon can look like a thin crescent, a half circle, or a big bright circle.

Every lesson is open to everyone for 7 days after it is published. This one came out on October 29, 2026: its text stays readable here, and its picture opens with a subscription.
The app is free. A subscription opens every lesson, in every school year.
Examples
- Looking up on different nights and seeing the Moon go from a thin sliver to a round circle
- Shining a torch on one side of a ball in a dark room so only that side glows
Key takeaways
- The Moon makes no light of its own; the Sun lights it up.
- The Moon looks like a different shape when we see more or less of its lit side.
