PLEASE DOWNLOAD AND SHARE: How do you explain the water cycle to a kid? You could draw diagrams. You could use big words like “evaporation” and “precipitation.” Or you could introduce them to Walter.
Walter is a cheerful little water molecule—round oxygen middle, two hydrogen ears—who dreams of seeing every corner of the planet. And in Walter the Water Molecule Takes a Journey, written and illustrated by Peter Wray, that’s exactly what he does.
The story follows Walter from the warm Gulf of Mexico, up into the clouds, over the mountains of West Virginia, down as a snowflake, into the Monongahela River, through a water treatment plant, out of a kitchen faucet, up through an oak tree, and back into the sky. Along the way, he reunites with his best friend Rio, makes new friends like Mote the aerosol, and learns that his journey—like all water—never really ends.
It’s science wrapped in storytelling. Kids get to experience the water cycle not as a textbook concept, but as an adventure with a character they can root for.
A Regional Connection
What makes this book especially fun for our audience? Walter’s journey brings him right through our backyard. He floats past the tall buildings of Pittsburgh. He splashes into the Monongahela. He tumbles down from the mountains of West Virginia.
For kids in the Upper Ohio River Basin, this isn’t just a story about water somewhere far away. It’s a story about their water.
