SIMPLE MACHINES

WHEELS, LEVERS, AND PULLEYS

Still, this is as solid a look at simple machines as any that exists outside of dry textbooks, and at least readers can...

Continuing to branch out into science concepts (Things That Float and Things That Don’t, 2013), the math and biography whiz tackles the elementary topic of simple machines.

Using sumi ink washes that have been digitally colored and arranged, Raff’s illustrations loosely follow three characters as they use simple machines: a Caucasian lumberjack dad (in faded red flannel), his blond son, and his playmate, an African-American boy with curly hair. Moving from wedge to inclined plane to lever to wheel and axle and finally to pulley, Adler presents the simple machines one by one, describing their parts and how they make work easier. He takes care to provide many examples that are sure to be familiar to readers: teeth (natural wedges!), playground equipment, a Ferris wheel, a screw, a flagpole. In addition to the machines, Adler explains friction. Terms in boldface stand out from the rest of the text, but there is no glossary or any backmatter at all to summarize or review the information presented; the absence is felt, especially since the book seems to just stop—there’s no closure.

Still, this is as solid a look at simple machines as any that exists outside of dry textbooks, and at least readers can imagine a narrative for the two young boys. (Informational picture book. 4-8)

THE PUMPKIN THIEF

From the Leaf Thief series

More fun antics to satisfy returning fans and snag new ones.

Not even the arrival of autumn can cool down this impetuous squirrel.

Although Squirrel is skeptical about Bird’s vegetable patch (“Nothing is HAPPENING!”), Bird does produce five (count them) lovely pumpkins. Squirrel picks out a favorite: “The enormous orange one.” Bird hints that Squirrel might want to help out; Squirrel sets out to fetch some work gloves and returns to find only four pumpkins. The frequently distracted Squirrel notices more gourds disappearing and leaps to the conclusion that a thief is near. And where’s Bird?! Has Squirrel’s pal also been taken? Diligently detecting, Squirrel finds clues—peck marks, footprints, and more—and produces a sketch of the suspect. As readers will guess, each clue turns out to point to one of Squirrel and Bird’s friends. Turns out Bird was delivering pumpkins to their pals while saving the big one to give to “my very best friend,” Squirrel. But why does Squirrel haul it up a tree? “So the Pumpkin Thief can’t find it, of course!” A page of pumpkin facts provides the learning component common to all titles in this series. Once more, readers will enjoy the pleasure of prediction and repetition, Squirrel’s silly persistence, Bird’s generosity, and the vibrant color illustrations, balancing orange with green.

More fun antics to satisfy returning fans and snag new ones. (Picture book. 4-8)

THE SUN THIEF

From the Leaf Thief series

A charming mix of science lesson and winsome storytelling.

The perky red squirrel introduced in The Leaf Thief (2020) is confused.

Bird and Squirrel both love summer, but when Bird calls out a cheery “Night night,” Squirrel, yawning himself, is incredulous: “BEDTIME? It can’t be! The sun’s still up, look!” Naturally there’s a lot more bewilderment ahead. Some weeks later, Squirrel is alarmed to see it’s dark at toothbrushing time. In skittish Squirrel’s view, a “sun thief”—who also made an odd “hoo” sound the other night—is responsible. Bird explains that as summer goes on, the sun sets earlier and earlier each night and reassures Squirrel that owls cry “hoo.” But the very next evening, at bathtime, Squirrel shines a bright light into the dark, sees something looming, and screams that the sun thief has “crashed into my tree!” Patient Bird, roused from slumber, points out that it’s just Bat. But “why was she flapping about in the dark?” Now Bird explains what nocturnal means. Once again, Squirrel is amusingly slow on the uptake, allowing readers to feel superior as Hemming gently folds in some science. Slater’s witty illustrations also lighten the lessons: Bird hangs a tiny T-shirt and shorts on a diminutive laundry line and sleeps tucked into a cozy repurposed sardine can, where a scared Squirrel attempts to squeeze in; Squirrel sports a pink bath towel and shower cap; a real thief quietly makes off with a couple of items (though Squirrel and Bird remain blissfully unaware).

A charming mix of science lesson and winsome storytelling. (info on light changes and diurnal/nocturnal) (Picture book. 4-8)
