(3) K-3 Illustrated by Katie Melrose. Using underwater microphones, we now know that “it’s NOISY down below!... / Fish GRUNT and GROAN, / fish SQUEAK and MOAN.” The text goes on to explain why and how sea animals use sound, from chirping angelfish to snapping shrimp. The rhyming and entertaining onomatopoeia-filled couplets impart an impressive amount of information; detailed and colorful spreads highlight the variety of underwater life. Back matter includes additional “Noisemaker Facts.”

(2) PS Illustrated by Elizabeth Goss. Rusch and Goss (All About Nothing, rev. 3/23) explore the playfulness of patterns. What is a pattern, they ask? Anything that repeats “over and over again.” Familiar objects such as LEGO bricks, pretzels, and striped candies populate the beginning pages, demonstrating that repetition. From the spiraling curls covering a child’s head to the ripples surrounding the legs of a dog standing in water, viewers’ eyes can spot at least one pattern on each spread. Patterns can be found all around, the book argues, but they can be made, too; our hands, feet, and bodies can create patterns as we clap and dance. Shifting from visual patterns to more abstract ones, the book proceeds to consider the patterns found in music, storytelling, and even the routines that make up children’s days. But what happens when a pattern is broken and our expectations fall to the wayside? A new baby may wreak havoc on an older child’s daily pattern, for example, but new patterns can always be built. This striking and inviting series installment will resonate both visually and emotionally with young readers as they consider the order of their world in a new way. Back matter expands upon patterns found in art. Worth repeating, indeed.

(2) K-3 Illustrated by Andrea Blinick. This imaginative and informative take on the water cycle begins with the fact that all living things are made mostly of water. “Why don’t you slosh when you run? Because all that water is held in your cells.” A child with long red hair and round turquoise glasses joyfully accompanies readers along water’s journey from the ocean up to the sky, down to the ground, and into our homes and our bodies…and back out into the atmosphere via our breath, sweat, tears, and urine. Blinick’s playful digital illustrations include such fanciful scenes as our young guide taking a refreshing drink of water, their flowing hair having morphed into ocean waves supporting a pink octopus, a mermaid, a surfer, and a sea monster, among other things. Alary’s breezy text encourages readers to consider not only how important this precious resource is but also the fact that “all the water that is is all that ever was.” Our drinking water, for example, “has been many things in many places at many times”—even snowflakes on the coat of a woolly mammoth. Alary doesn’t delve too deeply into these mind-expanding concepts, but the message about the importance of water to life on Earth is crystal clear. An appended author’s note provides more information and a gentle conservation message.

(2) K-3 Illustrated by Chris Hsu. In a cheerful picture book populated by Hsu’s inquisitive cartoon humans, Albee traces the history of the number zero. From the ancient Babylonians who invented place value four thousand years ago, to the Romans who developed a system of Vs, Is, and Xs; from the Mayans who had a concept of zero but no way to spread their idea to the rest of the world, to the Indian scribe who invented a symbol for zero and the Persian mathematician who popularized it, the invention of zero was a worldwide effort with triumphs and setbacks. Parts of Europe were perhaps the last to adopt the Hindu-Arabic number system, with Roman numerals persisting into the eighteenth century in some banking operations. (A timeline gives a “blurry” portrait of when various ­developments occurred.) The narrative treads lightly but doesn’t gloss over ways in which Western xenophobia and religious fanaticism delayed zero’s adoption. Meanwhile, the illustrations get into the spirit of archaeological inquiry with touches such as heritage breeds of dogs and sheep in the portrayal of historical communities and a nod to Halley’s comet. Philosophical considerations (“why create a symbol to represent nothing?”) and mention of the fields (e.g., physics, computing) that arose as a result of the Hindu-Arabic number system round out the presentation, while a few notes about definitions, a world map, and a bibliography complete the back matter. Place this book in the hands of a budding numerophile and watch them start to put two and two together.

(2) K-3 Illustrated by Manu Montoya. Mixed-media illustrations showcase the vibrant colors of a tropical rainforest and draw readers into this examination of a resident three-fingered sloth. Although slow-moving, the sloth and her young male offspring embark on a weekly “special mission,” the nature of which readers learn as the story unfolds. Small print below the main text provides facts that complement the action in the pictures (e.g., while shown descending a tree: sloths move at one-and-a-half miles per hour, as compared to humans’ maximum of twenty-seven and cheetahs’ of seventy). When our sloth finally lands on the forest floor, she completes that foreshadowed “special mission”: she “takes a big poop,” which consists of about a third of her body weight. Before returning to the forest canopy, she covers her poop with leaves (a behavior, scientists think, meant to keep it intact and thus make it easier for male sloths to locate females); and then she and her baby successfully evade a cheetah. Back matter includes brief illustrated descriptions of the seven kinds of sloths (all of which live in Central or South America) and provides two internet resources for further inquiry. A brief index concludes this entertaining and informative book.

(1) K-3 Illustrated by Juana Martinez-Neal. “When a sunbeam slips through a window in a certain slant of light, you can see a scattered sparkle: dust!” Light, airy illustrations dotted with golden specks float across the pages, lending a near-magical atmosphere to a story that starts with a mother-to-be in a child’s nursery and then travels through space and time, providing clear and fascinating scientific explanations of Saharan dust along the way. Saharan dust appears in a region adjacent to the now-dried-up Lake Chad in northern Africa and comprises fossilized animals once living in the area. With straightforward depictions in both text and illustrations, the huge plume of dust is shown visible from space (as the text notes, it weighs about the same as “one hundred and twenty million female hippos”). Particles float westward, feeding the ocean with nutrients and plankton with nourishment that is passed on to the marine animals that feed on them. When traveling over the Amazon rain-forest, the dust brings phosphorus, replenishing what’s been washed away with yearly rains. As Brockenbrough concludes, “This dust…of what lived once sustains what lives today.” An author’s note enlarges on the text and includes resources for further inquiry.

(1) K-3 Hatteras Island off the coast of North Carolina is the scene for Chin’s latest: an examination of a hurricane (based on several real ones) brilliantly told in segments alternating between actions of island residents and those of scientists. After piquing readers’ interest with a dramatic cover depicting an angry sea and a line of evacuating cars, Chin defines a hurricane and describes early tracking measures by meteorologists who observe the storm. A dual countdown begins. On Monday, the storm forms off the coast of Africa and moves west across the Atlantic as residents warily continue with their daily activities. On Tuesday, scientists follow the storm’s path; residents begin discussing arrangements. And so on. The climax occurs when the storm makes landfall. Short narrative descriptions and spot art depict what is happening on shore: the rising surf, the destructive winds, the calm of the eye, and the hurricane’s return with its change in wind direction. And then it’s over. People return to their homes and help one another with the cleanup. Chin (The Universe in You, rev. 1/23) masterfully juxtaposes the experience of people affected by the hurricane with the larger scientific context; stunning illustrations in pen and ink, watercolor, and gouache bring life to massive weather phenomena and to smaller-scale scenes. Extensive back matter adds useful details about storm formation, meteorology, and forecasting; an author’s note addresses concerns about the importance of the meteorological community’s work and the effects of climate change. Suggested sources for further inquiry complete this outstanding book.

(2) K-3 The life of an oak tree is beautifully depicted in this engaging informational picture book. It begins with a simple yet profound concept: "A blue jay drops an acorn, and a tree's life begins." The narrative follows the acorn as it grows into a sapling, matures into a towering tree, and becomes a vital part of a forest ecosystem -- providing shelter, food, and resources to birds, insects, and mammals for more than two centuries. It produces acorns, but the text details reasons they don't necessarily grow into new oak trees. It also effectively depicts the effects of changes over time in the tree's environment, and of human development, as the forest gives way to a town. Cole's detailed, fine-lined pen-and-ink illustrations bring depth and life to the natural elements on each spread. With intricate layers, and endless details to pore over (find the camouflaged creatures!), the black-and-white art complements the minimal text, allowing readers to immerse themselves in the beauty of nature. The text strikes a balance between storytelling and information, educating readers about the oak tree's role in its ecosystem. The back matter provides helpful resources, such as steps to create an ecosystem and a diagram of forest habitat layers.

(2) K-3 Worm acknowledges very early on that he can’t actually make a sandwich -- he is a small worm without hands, after all. What Worm can do, and with great enthusiasm, is eat garbage and poop it out to make a nutritious base for dirt in the garden that will grow vegetables for the promised sandwich. The lone human child in the story constructs a compost bin and fills it with plant-based food scraps, while Worm makes eye contact to ask for our patience and shares his favorite dirt recipe: “a little of this, a little of that, and compost.” We watch as the seeds for future-lunch are planted and slowly grow, while Worm’s refrain of “I’m sorry, but the [garbage / dirt / poop] is not for your sandwich” tamps down expectations of eating anytime soon. Under midsummer storm–darkened skies, Worm’s doubts set in: “GUUHHHHH!...Why did you ask a worm to make you a sandwich in the first place?” Then the sky clears, and the star of summer (and lunch) emerges on the vine: a ripe, round tomato. This ode to compost is neither preachy nor grody, and Worm is such a charming guide to the growing season that it’s easy to forget he didn’t actually prepare any sandwiches. Lush, cheerful watercolor and pencil illustrations are complex but not busy, and plants and critters are labeled with hand-drawn lettering. Back matter explains the nuts and bolts of composting.

(3) K-3 Illustrated by Stephanie Laberis. Part one of this book about animal play introduces play activities that have a purpose, such as hyenas having a tug-of-war to strengthen their jaws and otters “juggling” rocks to increase dexterity. Part two is about animal play that is just for fun, such as sledding ravens and body-surfing saltwater crocodiles. The text is informative and fascinating (who knew orangutans played dress-up?); the complementary digital illustrations, in mainly muted colors, show a variety of animals having a great time. A glossary and bibliography are appended.

(3) K-3 Tiny Habitats series. This informative picture book describes how a bison’s “steamy poo pile” becomes an important part of a prairie ecosystem. Over the course of a year, insects eat and lay eggs inside it; toads, turtles, and birds come to eat the bugs; flowers and grasses grow in the enriched soil. In the spring, a poo pile from a baby bison begins the cycle anew. Mixed-media illustrations depict the variety of life on the prairie; speech bubbles add personality (“Mmm, these roots are tangy!” muses a munching prairie dog). More background, a bibliography, and further reading are appended.

(2) K-3 Hodgson’s friendly science lesson introduces readers to the life cycle of an apple tree. Tree’s story begins when an apple falls to the ground, eventually allowing Seed to take root and begin to grow. As in When Moon Became a Moon (rev. 7/23), characters (e.g., Tree, Seed, Sun, Cloud, etc.) are depicted with expressive cartoon eyes and smiley mouths, and speech bubbles provide their humorous asides. Twelve short chapters highlight different phases of Tree’s growth. Bees, worms, and mushrooms (“I’m a fun guy!”) all make appearances. A handful of humans, with differing skin tones, abilities, and ages, are depicted interacting with trees in various settings. Tree’s role in the greater ecosystem is also highlighted, along with a connection between the protagonist and various trees that grow in other climates and locations. A consistent color palette and inviting aesthetic carry throughout the book. While the natural elements are anthropomorphized, the book solidly explains scientific concepts in an approachable manner, focusing on both the small and large aspects of a tree’s life.

(2) K-3 Illustrated by Lou Baker-Smith. Winter arrives in the Arctic. The days are shorter, the weather colder. A polar bear searches for a place to make a den, hibernate, and birth her twins. The trek across the ice is more difficult than in years before; ice floes are breaking up, and food has been scarce. Once on land, she finds a south-facing spot and settles down for the winter. The twins are born, she feeds them, and in the spring she and the cubs head toward the sea, where they can hunt for food. But conditions have changed: the ice is disappearing, creating fewer opportunities for them to hunt. Baker-Smith's soft mixed-media illustrations depict the bears' journey and are particularly effective in showing the degradation of the ice floes. Detailed back matter offers the main reason: climate change. In clear language, Jenkins describes the causes of Earth's warming and the effects not just for polar bears but for all life as climate change leads to an increase of extreme weather conditions. He concludes with suggestions individuals can follow to "make a difference when it comes to climate change." This brief glimpse into the experience of one polar bear ends, as it must, on a sober note of uncertainty about the future of the species.

(2) K-3 Summer in the northern polar regions finds a pair of Arctic terns caring for their two newly hatched chicks. In lushly illustrated landscapes of sea, ice, rock, and sky, they catch fish and fend off ravens, foxes, and polar bears. By fall, the young birds are strong enough to “follow the sun” thousands of miles south, all the way to the Antarctic, on the longest known migration journey of any animal on Earth. Moore’s poetic lines, just a few on most pages, include essential scientific details about the terns (“With bodies home / to hollow bones, / and wings like sails, / they soar on the wind”) and other animals they meet on their travels. Some of these encounters, as with a fish-stealing skua, are perilous, while others, as with the minke whale, are peaceful. Moore’s delicate watercolors are a marvel of animals in motion: soaring, diving, bobbing, reaching, schooling. Some are solo close-ups; others convey the awesome sight of multiple birds in flight. Back matter provides more information about the terns’ amazing twice-a-year journey.

(2) K-3 Illustrated by Anne Hunter. “He was the best dancer with the most powerful moves. He hissed loudly and bravely. He had a long, sleek neck and a fine bill. When he called her, she swam nearer.” And thus, two Canada geese mate for life. Every year these constant companions raise a clutch of goslings, migrate south in the winter, and return to the same spot each spring to birth and raise yet more young geese. But then the male dies. For days the female remains by his body and eventually stays behind and alone when the rest of the flock migrates south. Soft mixed-media illustrations, paired with gentle text, underscore not only the tranquility of the geese’s early life but also the isolation of the female’s existence after the death of her mate. Her seclusion ends a year later when she spots an unattached male and the two begin a life together. Back matter offers facts about Canada geese, validating a mourning period when a mate dies as well as opening up areas for further inquiry, such as habitat encroachment and the threat of lead poisoning; also appended with a brief bibliography of internet sources.

(2) K-3 Illustrated by Elke Boschinger. Pendreigh outlines the critical role that a tree plays in its ecosystem, both when it’s alive and upright and after it dies and has fallen. Spare, poetic text emulates the thrum of the forest: “Years pass. / Sapsuckers drill, / hidey-holes fill, / bear cubs rub / and claw.” Standing for years, the tree offers shade and resting places for birds and some mammals. Then, after roots weaken and soil lets loose (“crassshhhh!”), the tree takes on a new use as a nurse log, nurturing the forest in other ways. A collection of earth-bound creatures finds “a place to grow, / to rest, / to shelter.” Even as her bark de-cays, the nurse log continues to provide nutrients to bolster new trees growing atop her; she sustains a cycle of life until the next tree can do the same. Boschinger’s detailed digital illustrations amplify the lushness of a diverse forest biome. Back matter follows a question-and-answer format, offering readers more to learn about the roles of nurse logs in their respective environments.

(2) K-3 Illustrated by Gillian Eilidh O'Mara. This nonfiction picture book tells the intriguing story of Walnut, a white-naped crane who imprinted on a human when she first hatched in 1981. Over the next two decades, she is subsequently sent to, and removed from, multiple zoos due to aggressive behavior. At the age of twenty-four, she enters a specialized breeding program for endangered cranes under the care of the Smithsonian's National Zoo and Conservation Biology Institute (NZCBI), where she forms a close relationship with crane keeper Chris Crowe. Pincus skillfully weaves information about animal behavior and themes of trust and companionship into a story that highlights how patience and understanding can lead to extraordinary connections. The text is informative and accessible, detailing Walnut's journey while emphasizing the importance of conservation and explaining the critical role of breeding programs in preserving wildlife. O'Mara's digital illustrations, using soft colors that beautifully capture the realistic expressions of the crane, effectively convey the bond between bird and human. Back matter includes a glossary, a bibliography and resources, an interview with Crowe, and further information about NZCBI.
