Swirl by Swirl: Spirals in NatureHardcover, 4 October 2011

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, Joyce Sidman's poetry paired with Beth Krommes's scratchboard illustrations 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.
