Explore the science and sparkling wonder of snow in this informative, lyrical read-aloud picture book from award-winning author Laura Purdie Salas.
Crystals grow. Branches break.
Melding crystals make a flake.

Soft and silent, oh so slow . . .
Snowflakes drift
and float
and blow.

To create snow, two factors are essential. First, it has to be cold—not just on the ground, but also miles above the earth, where snowflakes form. Second, there must be moisture—water vapor—in the air. Cold air without moisture is just cold air. But cold air plus moisture? That’s the recipe for a snowstorm.

Laura Purdie Salas's dynamic, poetic text and Chiara Fedele's vibrant art offer the perfect introduction to the science of weather and the forces that work together to create a wintry snowstorm.

An author’s note delves deeper into the science of snow.
