The science, gently
- The moon makes no light of its own; we see whichever half the sun is lighting.
- A full cycle of phases, new moon to new moon, takes about twenty-nine and a half days.
- The same face of the moon always looks at Earth; the far side is not dark, only private.
Wonder together
- What phase is the moon in tonight? Can you name it?
- Why do you think people used moons to count months?
- If the moon kept a diary, what would this week's entry say?
Tonight's calm-down
Whatever slice of moon is out tonight, it is the same whole moon, patient behind its shadow. You are whole in the dark too. Wax and wane your breath: fuller, thinner, fuller, thinner, gone.

There's so much more to explore.
The episode is a whole story on its own. But if the wondering keeps going after the audio ends, the Family Guide opens this one all the way up: the same calm voice, turned into something you can do together at the table the next morning.
