Swirl by Swirl: Spirals in Nature

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.
