THINGS THAT FLOAT AND THINGS THAT DON'T

A boy, a girl and a dog demonstrate that things float in water when they are less dense than the water around them.

Adler, who has demystified math for young readers for years in titles ranging from Roman Numerals (1977) to Millions, Billions, and Trillions (2013) turns his attention to physics with this simple but effective explanation of principles of flotation and density. His clear, logical text invites readers to experiment with different objects, to shape boats, and to make both ice and salt water mixtures. Raff’s illustrations take this invitation further, showing a pair of children using toy boats, plastic bottles, pennies, aluminum foil, clay and ice to discover what things float and why. These digitally combined ink washes and drawings add interest and some humor, supporting and enriching the text, except on one page. There, a line showing the water level of a bottle to which salt has been added seems to show that the water level has risen though the author makes clear that the level should not change. Curiously, the series of experiments stops at that point rather than continuing with the denser salt water, as good teachers would encourage children to do.

This appealing introduction can serve as a springboard for further investigations. (Informational picture book. 5-8)

ADA TWIST, SCIENTIST

Her intellectual curiosity is surpassed only by her passion for science. But what to do about her messy experiments?

Ada is speechless until she turns 3. But once she learns how to break out of her crib, there’s no stopping the kinky-haired, brown-skinned girl. “She tore through the house on a fact-finding spree.” When she does start speaking, her favorite words are “why,” “how,” and “when.” Her parents, a fashion-forward black couple who sport a variety of trendy outfits, are dumbfounded, and her older brother can only point at her in astonishment. She amazes her friends with her experiments. Ada examines all the clocks in the house, studies the solar system, and analyzes all the smells she encounters. Fortunately, her parents stop her from putting the cat in the dryer, sending her instead to the Thinking Chair. But while there, she covers the wall with formulae. What can her parents do? Instead of punishing her passion, they decide to try to understand it. “It’s all in the heart of a young scientist.” Though her plot is negligible—Ada’s parents arguably change more than she does—Beaty delightfully advocates for girls in science in her now-trademark crisply rhyming text. Roberts’ illustrations, in watercolor, pen, and ink, manage to be both smart and silly; the page compositions artfully evoke the tumult of Ada’s curiosity, filling white backgrounds with questions and clutter.

Cool and stylish. (Picture book. 5-8)

ROSIE REVERE, ENGINEER

Rhymed couplets convey the story of a girl who likes to build things but is shy about it. Neither the poetry nor Rosie’s projects always work well.

Rosie picks up trash and oddments where she finds them, stashing them in her attic room to work on at night. Once, she made a hat for her favorite zookeeper uncle to keep pythons away, and he laughed so hard that she never made anything publicly again. But when her great-great-aunt Rose comes to visit and reminds Rosie of her own past building airplanes, she expresses her regret that she still has not had the chance to fly. Great-great-aunt Rose is visibly modeled on Rosie the Riveter, the iconic, red-bandanna–wearing poster woman from World War II. Rosie decides to build a flying machine and does so (it’s a heli-o-cheese-copter), but it fails. She’s just about to swear off making stuff forever when Aunt Rose congratulates her on her failure; now she can go on to try again. Rosie wears her hair swooped over one eye (just like great-great-aunt Rose), and other figures have exaggerated hairdos, tiny feet and elongated or greatly rounded bodies. The detritus of Rosie’s collections is fascinating, from broken dolls and stuffed animals to nails, tools, pencils, old lamps and possibly an erector set. And cheddar-cheese spray.

Earnest and silly by turns, it doesn’t quite capture the attention or the imagination, although surely its heart is in the right place. (historical note) (Picture book. 5-7)
