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)

ADA LACE, ON THE CASE

From the Ada Lace series , Vol. 1

The story feels a bit contrived, but Ada will be a welcome addition to the small circle of science-loving girls in the...

Using science and technology, third-grader Ada Lace kicks off her new series by solving a mystery even with her leg in a cast.

Temporarily housebound after a badly executed bungee jump, Ada uses binoculars to document the ecosystem of her new neighborhood in San Francisco. She records her observations in a field journal, a project that intrigues new friend Nina, who lives nearby. When they see that Ms. Reed’s dog, Marguerite, is missing, they leap to the conclusion that it has been stolen. Nina does the legwork and Ada provides the technology for their search for the dognapper. Story-crafting takes a back seat to scene-setting in this series kickoff that introduces the major players. As part of the series formula, science topics and gadgetry are integrated into the stories and further explained in a “Behind the Science” afterword. This installment incorporates drones, a wireless camera, gecko gloves, and the Turing test as well as the concept of an ecosystem. There are no ethnic indicators in the text, but the illustrations reveal that Ada, her family, and bratty neighbor Milton are white; Nina appears to be Southeast Asian; and Mr. Peebles, an inventor who lives nearby, is black.

The story feels a bit contrived, but Ada will be a welcome addition to the small circle of science-loving girls in the chapter-book world. (Fiction. 7-9)
