Branching, spiraling, spinning―you can find patterns almost anywhere in
nature, if you look for them. This book is a starting point that
introduces kids to some major patterns in the natural world. Just as the
branches of a tree spread upwards into the sky, roots branch deep into
the ground. Branches also spread through our bodies, inside our lungs
and veins. Storms and snail shells spiral; electrons and galaxies spin.
