Cool! Snow really has the power to wow—and teaches math, too.
Snow descends mathematically.
We intuitively understand that when snow falls, huge numbers of snowflakes combine to form a white cover. This book demonstrates that there’s also a mathematical way to regard snowfall: Consider snowflakes falling in pairs, then multiply them exponentially. The book starts with two snowflakes, which increase in number over the course of the story. At the bottom of each page, a caption shows the base number 2 with an exponent—for instance, on the page labeled “Eight flakes twirl,” the caption reads “2³ = 2 to the third power / 2 x 2 x 2 = 8.” It all culminates with 2 to the 14th power, or 16,384 snowflakes. The correct number of snowflakes is depicted on each page, and when the numbers are manageable, readers may actually count them in the artwork. The text is delivered in simple, lively verse. Younger kids likely won’t get the math, not having learned multiplication yet, but they’ll appreciate fun vocabulary like swoosh and sashay. Older kids who’ve studied multiplication will understand more and appreciate learning how to multiply the same number repeatedly. The lush, textured illustrations, created from cut pieces of painted-paper collage, then assembled digitally, capture nature at its wintry best. Two children—one light-skinned, one brown-skinned—are depicted playing in the snow. (This book was reviewed digitally.)

An in-depth and visually pleasing look at one of the most fundamental forces in the universe.
An introduction to gravity.
The book opens with the most iconic demonstration of gravity, an apple falling. Throughout, Herz tackles both huge concepts—how gravity compresses atoms to form stars and how black holes pull all kinds of matter toward them—and more concrete ones: how gravity allows you to jump up and then come back down to the ground. Gravity narrates in spare yet lyrical verse, explaining how it creates planets and compresses atoms and comparing itself to a hug. “My embrace is tight enough that you don’t float like a balloon, but loose enough that you can run and leap and play.” Gravity personifies itself at times: “I am stubborn—the bigger things are, the harder I pull.” Beautiful illustrations depict swirling planets and black holes alongside racially diverse children playing, running, and jumping, all thanks to gravity. Thorough backmatter discusses how Sir Isaac Newton discovered gravity and explains Albert Einstein’s theory of relativity. While at times Herz’s explanations may be a bit too technical for some readers, burgeoning scientists will be drawn in.

Enticing and eco-friendly.
Why and how to make a rain garden.
Having watched through their classroom window as a “rooftop-rushing, gutter-gushing” downpour sloppily flooded their streets and playground, several racially diverse young children follow their tan-skinned teacher outside to lay out a shallow drainage ditch beneath their school’s downspout, which leads to a patch of ground, where they plant flowers (“native ones with tough, thick roots,” Schaub specifies) to absorb the “mucky runoff” and, in time, draw butterflies and other wildlife. The author follows up her lilting rhyme with more detailed explanations of a rain garden’s function and construction, including a chart to help determine how deep to make the rain garden and a properly cautionary note about locating a site’s buried utility lines before starting to dig; she concludes with a set of leads to online information sources. Gómez goes more for visual appeal than realism. In her scenes, a group of smiling, round-headed, very small children in rain gear industriously lay large stones along a winding border with little apparent effort; nevertheless, her images of the little ones planting generic flowers that are tall and lush just a page turn later do make the outdoorsy project look like fun.
Enticing and eco-friendly. (Picture book. 5-7)Pub Date: March 12, 2024
