LINES, BARS AND CIRCLES

HOW WILLIAM PLAYFAIR INVENTED GRAPHS

An unusual and useful curricular choice for today’s students, who frequently learn through infographics.

The origins of the now-ubiquitous line graph, bar graph, and pie chart are rarely considered. This title introduces the Scotsman who first plotted and promoted these tools for easily communicating complex information.

When the father of William Playfair (1759-1823) died, his brother John took over the young dreamer’s education. John’s scientific training had a lasting influence, according to extensive backmatter, which quotes Playfair: “He taught me to know, that, whatever can be expressed in numbers, may be represented by lines.” (There are no citations, nor a bibliography, although Playfair’s books are mentioned in context.) Becker chronicles a career of dabbling that included apprenticeships with inventors, among them James Watt. She writes clearly with a child audience in mind, highlighting the drama surrounding this economist, entrepreneur, thief, and scoundrel and explaining why graphs did not gain traction in his lifetime: reputation and ideas were inextricably linked, and the prevailing notion was that science was best expressed in numbers and formulas, not frivolous illustrations. Insets summarize the scientific method and the Industrial and French revolutions. Rendered digitally in a predominantly turquoise, blue, and green palette, Tremblay’s caricatures (all white before the book reaches the present day) provide comic relief, as when a dotted line severs Louis XVI’s head. Two graphs and a pie chart are depicted and deconstructed; original versions occur in the author’s note.

An unusual and useful curricular choice for today’s students, who frequently learn through infographics. (Picture book/biography. 6-9)

ADA TWIST AND THE PERILOUS PANTS

From the Questioneers series , Vol. 2

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.

Adventure, humor, and smart, likable characters make for a winning chapter book. (Fiction. 6-9)

TIDE POOL TROUBLES

From the Shelby & Watts series , Vol. 1

Models attention to detail and deductive reasoning in a fun beach setting, complete with interesting facts.

Beachcombers and shell seekers, gather ’round and meet Shelby and Watts, Planetary Investigators.

When Fred the hermit crab can’t find a new, larger shell to move into, he seeks out the “brilliant brains” of Shelby and Watts. Shelby, a fox, is the detective in the duo, and Watts, a badger, loves facts, adding simple fun ones—about hermit crabs, tides, tide-pool dwellers, how shells are used, etc.—throughout the story. Watts also loves to catalog clues in his notebook. In fact, the first mystery that Shelby solves is that of Watts’ lost notebook. Young readers can watch Shelby investigate, solve, and explain her deductive process, all while learning to carefully examine all the details in each graphic panel. Once the missing shells are found, it’s “time for the hermit crab shuffle,” in which the members of a colony of hermit crabs all line up and trade up to larger homes. Final pages include “Earth-Saving Tips from Shelby & Watts,” such as taking pictures of shells instead of collecting them, eating seafood from sustainable sources, and cleaning up the beach. The seven chapters are of varying length, but with several one-panel pages and many pages with low word count, the book is shorter than it appears, which should be a confidence boost for young readers. (This book was reviewed digitally.)
