UNDER YOUR FEET

Peeks under lots of rocks and logs but barely scratches the surface.

A view of the “important jobs” that soil and all the things that live in it have.

Considering the uncountable plants, animals, fungi, and microbes that live there, soil is a busy place—as the page design goes overboard in reflecting, with floating labels, teeming dollops of fact in diverse typefaces, snippets of photographs, and larger images done in a printlike style shoveled together in high-density arrays of angled or undulating lines on every spread. After opening with an overview of soil’s roles, particularly in regulating climate, the discourse plows through its organic and inorganic elements, how it varies in different environments, the living things that populate it, and, in broader context, how the dusty surfaces of the moon and Mars compare. Earthworms are such major players that they get two spreads of their own, six mentions of their “poop,” and instructions for setting up a catch-and-release “worm hotel.” Because the visuals are more about flash than furthering understanding, and the authors too seem bent on cramming in the dazzle (“Astronauts tried tasting moon dust!”), readers with a yen to dig deep may just scuff through this before going on to more fertile surveys like Marc ter Horst’s Hey There, Earth Dweller, illustrated by Wendy Panders and translated by Laura Watkinson (2019), or Tom Jackson’s Earth Sciences (2019).

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.

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).
