An eye-glazing overview.
A quick summary of sleep’s purposes, stages, and disorders, with advice about how to get more of it.
Bjazevich starts off in an informational rush with mentions of “circadian rhythms,” “homeostatic sleep drive,” and the brain’s “suprachiasmatic nucleus” on the very first page—but then goes on to dish out a mishmash of qualified claims and broad generalities: “Reduced health risks” are one of sleep’s “potential benefits” and that it’s “not uncommon” for people who are deaf to sign in their sleep. Late naps, caffeinated drinks, or electronic devices used too close to bedtime “might make sleeping more difficult.” Outdoor exercise “may improve and promote sleep.” Alarmingly, childhood growth “could be slowed or stunted” by a consistent lack of down time. Diabetes and obesity have also been linked to too little sleep…but also too much (“more research is needed.” No kidding). Along with splashes of bright color, Eigner poses a large cast of figures, mostly children, all of whom range in skin tone, bedding down or posing as simplified anatomical models. The author does broaden her scope with closing pages of sleeping animals and of different types of beds throughout history and all over the world, from futons to hammocks. Still, young readers (or their parents) in search of practical and effective ways to achieve healthy sleep habits will come away with a clear impression that science has little to offer beyond equivocations.

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).
