Book Review/Giveaway: Swirl by Swirl: Spirals in Nature. Ends July 19th

 

 

Swirl by Swirl: Spirals in Nature by Joyce Sidman and illustrated by Beth Krommes

About the book: 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? Spiral – bold, beautiful, and mysterious – are all around us. Can you find one?

My Review: This is a beautiful illustrated book that tells what makes things like snail shells, bull snake, eastern chipmunk, millipede, hibiscus, sunflower, funnel tornado, and many more spirals.  Mathematic explains that a spiral is a curve in the plane or in the space, which runs around a centre in a special way.

This spirals in nature shows how the bull snakes, woodchuck, harvest mouse and more like to coil tight in small places to keep warm and safe. In some animals and plants spiral shape start small and gets bigger and swirl, like the swimming nautilus, lady fern.  Some use their spiral to defend themselves like the Merino sheep while the spider monkeys use theirs to hold on tight.

Highly recommend this beautiful book for classroom teaching.
