A basic introduction to the properties and measurement of sound.
A short-haired, brown-skinned child and a dog with a bandanna around its neck serve as cheerful guides through informal informational text and textured, cartoon illustrations. Everyday scenes, like a busy city street, appear alongside more fanciful ones, like a dog-versus-child drag race. Descriptions of various sounds lead into explanations of sound’s forms and functions as well as related facts about animals (for example, bats use echolocation) and prompts for experiments that readers can do on their own (like feeling for vibrations in your neck when you hum). Concentric circles and repeated curves help readers spot sound waves in every situation. The content is broader than it is deep: While it doesn’t contain a complete physical description of a pressure wave, for instance, it does have a simple basic explanation of how sounds travel from the world into our brains. It doesn’t diagram human inner ear bones, either, but it does feature a nifty graph of the hearing ranges of 12 different animals. One notable misstep is the spread about decibels, which fails to communicate that this measure of sound’s power doesn’t increase in linear fashion; 20 dB is not 10 plus louder than 10 dB, but 10 times louder. That’s pretty important for readers trying to follow the recommendation “To keep your ears safe, stay away from really loud noise”! (This book was reviewed digitally.)

This book is buzzing with trivia.
Follow a swarm of bees as they leave a beekeeper’s apiary in search of a new home. As the scout bees traverse the fields, readers are provided with a potpourri of facts and statements about bees. The information is scattered—much like the scout bees—and as a result, both the nominal plot and informational content are tissue-thin. There are some interesting facts throughout the book, but many pieces of trivia are too, well trivial, to prove useful. For example, as the bees travel, readers learn that “onion flowers are round and fluffy” and “fennel is a plant that is used in cooking.” Other facts are oversimplified and as a result are not accurate. For example, monofloral honey is defined as “made by bees who visit just one kind of flower” with no acknowledgment of the fact that bees may range widely, and swarm activity is described as a springtime event, when it can also occur in summer and early fall. The information in the book, such as species identification and measurement units, is directed toward British readers. The flat, thin-lined artwork does little to enhance the story, but an “I spy” game challenging readers to find a specific bee throughout is amusing.
Friends of these pollinators will be best served elsewhere. (Informational picture book. 8-10)Pub Date: May 18, 2021

BOOK REVIEW
A charged-up roundup of astro-facts.
Having previously explored everything awesome about both dinosaurs (2019) and sharks (2020), Lowery now heads out along a well-traveled route, taking readers from the Big Bang through a planet-by-planet tour of the solar system and then through a selection of space-exploration highlights. The survey isn’t unique, but Lowery does pour on the gosh-wow by filling each hand-lettered, poster-style spread with emphatic colors and graphics. He also goes for the awesome in his selection of facts—so that readers get nothing about Newton’s laws of motion, for instance, but will come away knowing that just 65 years separate the Wright brothers’ flight and the first moon landing. They’ll also learn that space is silent but smells like burned steak (according to astronaut Chris Hadfield), that thanks to microgravity no one snores on the International Space Station, and that Buzz Aldrin was the first man on the moon…to use the bathroom. And, along with a set of forgettable space jokes (OK, one: “Why did the carnivore eat the shooting star?” “Because it was meteor”), the backmatter features drawing instructions for budding space artists and a short but choice reading list. Nods to Katherine Johnson and NASA’s other African American “computers” as well as astronomer Vera Rubin give women a solid presence in the otherwise male and largely White cast of humans. (This book was reviewed digitally.)
