NATURE AT NIGHT

Both casual browsers and budding zoologists will light up.

A gallery of luminous natural beauties (not necessarily nocturnal), from puffins to polar lights.

Leading off with a lenticular 3-D cover image of a hawksbill sea turtle glimmering red and green, this (stock) photo gallery spans land, sea, and sky to present 23 lambent wonders—all animals except for the foxfire mushroom and the northern and southern auroras—enhanced by glow-in-the-dark highlights. Even without that gimmick the figures seem luminous against the deep, black backgrounds. Nor is the glow always external; chameleons shine from their very bones; fimbriated moray eels gleam in part from internal organs; and the mushrooms, an orange octopus, and several others in the lineup at least look brightly lit from within. Aside from occasional bobbles, such as a claim that glowworms luminesce as larvae opposite a photo of flashing adults and contradictory observations that polka-dot tree frogs shine either by natural or only in ultraviolet light, Regan’s lucid, specific remarks about how each organism makes and uses its lights are spot-on. Anita Sitarski’s Cold Light (2007) offers less-dazzling photography but makes a natural follow-up since it illuminates a wider range of examples (including light-producing rocks and minerals) in greater detail.

Both casual browsers and budding zoologists will light up. (glossary) (Informational picture book. 7-9)

I AM GRAVITY

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.

An in-depth and visually pleasing look at one of the most fundamental forces in the universe. (Informational picture book. 7-9)

HOW TO EXPLAIN CODING TO A GROWN-UP

From the How To Explain Science series

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).
