A Caldecott medalist and a Newbery Honor-winning poet celebrate the beauty and value of spirals.What makes the tiny snail shell so beautiful? Why does that shape occur in nature over and over again—in rushing rivers, in a flower bud, even inside your ear?
With simplicity and grace, Krommes and Sidman not only reveal the many spirals in nature — from fiddleheads to elephant tusks, from crashing waves to spiraling galaxies — but also celebrate the beauty and usefulness of this fascinating shape.
