Snowflakes: Winter's Quiet Blanket
Every snowflake is a six-sided diary of the cloud it fell through. This episode follows one flake's build, from speck to star to blanket.
The science, gently
- Snowflakes grow six arms because of the shape water molecules take when they freeze.
- Each flake's pattern records the temperature and moisture of its exact path down.
- Fresh snow is mostly trapped air, which is why it hushes the whole street.
Wonder together
- Why six, do you think, and never five or seven?
- What would your falling-path diary say about today?
- What is the quietest the world has ever sounded to you?
Tonight's calm-down
Snow quiets the world by holding air gently, and your blanket does the same. Fall once, slowly, land softly, and let the whole street of you go hushed.
