A broad-(key)strokes rather than nuts-and-bolts computer-science introduction.
An introduction to programming concepts, framed around the notion of telling computers what to do.
Through questions and answers, this book walks young readers from the ideas of computer languages and input and output to data variables, Boolean logic, and loops. The questions come in pairs, the first straightforward and the second ludicrously silly, providing humor and a chance for an audience response of “No!” For example, the text asks if computers and programs use phones to call or text with users to determine when to run a program, if computers keep track of programs via a “secret diary,” and if computers flip coins to determine whether or not to do something—that question comes with charming art of a computer unplugging itself in response to a coin flip. The lively art—cartoon drawings with a thin line, frequently on graph-paper backgrounds—implies notebook doodles and features ethnic diversity among the depicted children. A superfluous final section, illustrated with photos of diverse children, gives examples of programmed technologies such as televisions, vending machines, cellphones, laptops, and gaming consoles. The text features overly wordy passages and suffers from sentence-to-sentence redundancies. That said, the explanations are all solid, and the computer-logic portions—Boolean, if-else statements, and loops—are demonstrated well through speech-bubble exchanges among characters. A glossary concisely defines terms.

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.

More thoughtful, sometimes exhilarating encounters with nature.
In a new entry in the Over and Under series, a paddleboarder glimpses humpback whales leaping, floats over a populous kelp forest, and explores life on a beach and in a tide pool.
In this tale inspired by Messner’s experiences in Monterey Bay in California, a young tan-skinned narrator, along with their light-skinned mom and tan-skinned dad, observes in quiet, lyrical language sights and sounds above and below the sea’s serene surface. Switching perspectives and angles of view and often leaving the family’s red paddleboards just tiny dots bobbing on distant swells, Neal’s broad seascapes depict in precise detail bat stars and anchovies, kelp bass, and sea otters going about their business amid rocky formations and the swaying fronds of kelp…and, further out, graceful moon jellies and—thrillingly—massive whales in open waters beneath gliding pelicans and other shorebirds. After returning to the beach at day’s end to search for shells and to spot anemones and decorator crabs, the child ends with nighttime dreams of stars in the sky meeting stars in the sea. Appended nature notes on kelp and 21 other types of sealife fill in details about patterns and relationships in this rich ecosystem. (This book was reviewed digitally.)
