For visual learners, this is a particularly accessible demonstration of an intriguing concept.
Through examples of what fractals are and what they aren’t, this photo essay introduces a complex mathematical idea in a simple, inviting way.
Using a straightforward text and eye-catching photographs, the Campbells start with the familiar: spheres, cones, cylinders—shapes readers can find and readily name in their environments. But then they move on to the more elaborate forms: a head of broccoli, the flower of a Queen Anne’s lace, a tree. In 1975, Benoit Mandelbrot gave a name to natural shapes with smaller parts that look like the whole shape. He called them fractals. Photographs of whole and divided flower and broccoli heads, set on plain backgrounds, demonstrate how smaller parts repeat the shape of the whole. A double-page spread of forked lightning shows another example. Even mountain ranges are made of smaller mountains. Further, smaller images remind readers that the shapes can be called fractals only if the repeating parts diminish in size. In conclusion, the author of Growing Patterns (2010) provides instructions for drawing the interesting fractal pattern that surrounds each page number. An afterword by mathematician Michael Frame offers more information about Mandelbrot and introduces the possibility of a real-world application of this abstract idea: invisibility cloaks!

Adventure, humor, and smart, likable characters make for a winning chapter book.
Ada Twist’s incessant stream of questions leads to answers that help solve a neighborhood crisis.
Ada conducts experiments at home to answer questions such as, why does Mom’s coffee smell stronger than Dad’s coffee? Each answer leads to another question, another hypothesis, and another experiment, which is how she goes from collecting data on backyard birds for a citizen-science project to helping Rosie Revere figure out how to get her uncle Ned down from the sky, where his helium-filled “perilous pants” are keeping him afloat. The Questioneers—Rosie the engineer, Iggy Peck the architect, and Ada the scientist—work together, asking questions like scientists. Armed with knowledge (of molecules and air pressure, force and temperature) but more importantly, with curiosity, Ada works out a solution. Ada is a recognizable, three-dimensional girl in this delightfully silly chapter book: tirelessly curious and determined yet easily excited and still learning to express herself. If science concepts aren’t completely clear in this romp, relationships and emotions certainly are. In playful full- and half-page illustrations that break up the text, Ada is black with Afro-textured hair; Rosie and Iggy are white. A closing section on citizen science may inspire readers to get involved in science too; on the other hand, the “Ode to a Gas!” may just puzzle them. Other backmatter topics include the importance of bird study and the threat palm-oil use poses to rainforests.

An unusual offering for the young geology nerd.
This British import is an imaginatively constructed sequence of images that show a white boy examining a city pavement, clearly in London, and the sights he would see if he were able to travel down to the Earth’s core and then back again to the surface.
The geologic layers are depicted in 10 vertical spreads that require a 90-degree turn to be read and include endpapers, which open out, concertina fashion, to show the interior of the Earth to its core. Beneath the urban setting are drains, pipes, and artifacts of urban infrastructure. Below that, archaeological relics are revealed. An Underground train speeds by, and below it, a stalactite-encrusted cave yawns. Deep below the Earth’s crust, magma, the Earth’s mantle, and the inner core are shown. Turn the page to start going up again, back through the mantle to the crust, where precious minerals are revealed, then fossils, tree roots, and animal burrows, ending with the same boy in the English countryside. The painted, stenciled, and collaged illustrations are full-bleed, and the tones graduate pleasantly from light colors at the surface of the Earth to rich pinks, yellows, and oranges as readers near the Earth’s core. The text is informative, if lacking in poetry, including such nuggets as “earthworms are expert recyclers, eating dead plants in the soil.”
