Big and small, a snowflake story. Two snowflakes have a conversation. One is big and has six branches (Big). The other (Small) is a tiny hexagonal column. Big: "Hi. I'm a snowflake." Small: "Me too." Big: "Really? We look so different." Small: "Totally. Why is that?" Big: "The air I fell from had lots of water vapor." Small: "The air I came from had less water vapor. And the air was VERY, very cold!" Big: "Wow. The air I came from was not much colder than freezing." (Two thermometers are pictured, one with the temperature near freezing, the other's temperature is much lower.) Big: "I like you just the way you are, little flake." Small: "Awww, that's sweet. You're going to make me melt."

Snowflakes come in all shapes and sizes, depending on the temperature and the amount of water vapor in the air. Collect snowflakes as they fall on a sheet of dark paper and take a look at their shapes. Peruse the Snow Crystals online gallery to find beautiful magnified photographs of snowflakes.
