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.

A lighthearted first look at an increasingly useful skill.
Grown-ups may not be the only audience for this simple explanation of how algorithms work.
Taking a confused-looking hipster parent firmly in hand, a child first points to all the computers around the house (“Pro Tip: When dealing with grown-ups, don’t jump into the complicated stuff too fast. Start with something they already know”). Next, the child leads the adult outside to make and follow step-by-step directions for getting to the park, deciding which playground equipment to use, and finally walking home. Along the way, concepts like conditionals and variables come into play in street maps and diagrams, and a literal bug stands in for the sort that programmers will inevitably need to find and solve. The lesson culminates in an actual sample of very simple code with labels that unpack each instruction…plus a pop quiz to lay out a decision tree for crossing the street, because if “your grown-up can explain it, that shows they understand it!” That goes for kids, too—and though Spiro doesn’t take the logical next step and furnish leads to actual manuals, young (and not so young) fledgling coders will find plenty of good ones around, such as Get Coding! (2017), published by Candlewick, or Rachel Ziter’s Coding From Scratch (2018).

Young makers will find the Scrap Pack’s enthusiasm infectious, but even as broad overviews, these offer at best incomplete...
A mouse, a bird, and a junkyard frog assemble a car from the ground up—cluing in readers who may be a bit vague on what’s beneath all those hoods…or at least what used to be.
Enlisting his green buddy Hank to supply the parts and feathered Phoebe to draw up the plans, Eli, “king of crazy ideas,” sees his latest project grow from a frame and some miscellaneous loose parts to a nifty blue convertible with a classic 1950s look. At each stage, Sodomka supplies clearly drawn angled or cutaway views with dozens of major components labeled, from “steering knuckle bracket” to “tie rod” and “ball joint.” The gas tank is labeled but seems to be missing, though, and readers who want to know what a “differential” actually does or the purpose of the “indicator switch” are out of luck. Lacey’s claim that an engine “is like the brain of the car” doesn’t bear close examination, either. Moreover, the finished auto isn’t much like most modern cars, as it has no electronic elements, for instance, and is powered by a three-cylinder engine (misleadingly billed as “regular”) quaintly fed by a long-obsolescent carburetor. With an auto under their belts (and with similar oversimplification), Eli’s “Scrap Pack” goes on to an even more ambitious enterprise in How to Build a Plane. In both volumes, closer looks at selected systems or related topics follow the storyline’s happy conclusion, and each broad trial-and-error step in the construction is recapped at the end.
Young makers will find the Scrap Pack’s enthusiasm infectious, but even as broad overviews, these offer at best incomplete pictures. (Informational picture book. 7-9)Pub Date: Nov. 1, 2015
