EVIDENCE!

HOW DR. JOHN SNOW SOLVED THE MYSTERY OF CHOLERA

A page-turning medical mystery that makes a compelling case for following the facts.

Dr. John Snow, “the father of modern epidemiology,” discovers the cause of cholera.

Behind every great scientist is evidence. When cholera broke out in London in 1854, most people blamed the “bad, smelly air” for the rapid spread of the disease. The English physician Dr. John Snow had a “bold hypothesis.” He had noticed that cholera’s symptoms included vomiting and diarrhea, so the cause was likely what the victims had ingested rather than something airborne. All he needed was evidence! With expert pacing, Hopkinson sets up Snow’s story as a medical mystery and a race against time. The doctor follows clues, gathers information about where the deceased people lived, plots his data on maps, notices clusters of disease, interviews local residents, and discovers the one thing the dead had in common: They had drunk from the same water pump. Henderson’s moody, expressionistic art captures Londoners’ confusion and concern, while Dr. Snow’s urgent pace is marked with literal dashes across city maps. Hopkinson nimbly acknowledges when she’s using conjecture—“We can guess the hard questions he must ask”—and makes clear when she’s presenting evidence: “This fact is helpful.” At the story’s climax, Dr. Snow presents his findings at a neighborhood meeting, and in a final, incandescent spread, the water pump’s handle is removed—“a milestone in science, a shining moment in the long fight against epidemics.”

A page-turning medical mystery that makes a compelling case for following the facts. (the case against the Broad Street pump, more information on Dr. Snow, list of major infectious diseases and their causes, internet resources, books on Dr. Snow and on epidemics) (Informational picture book. 4-8)

I AM THE RAIN

A lyrical and educational look at the water cycle.

Through many types of weather and the different seasons, water tells readers about its many forms.

“Sometimes I’m the rain cloud / and sometimes I’m the rain.” Water can make rainbows and can appear to be different colors. Water is a waterfall, a wave, an ocean swell, a frozen pond, the snow on your nose, a cloud, frost, a comet, a part of you. Throughout, Paterson’s rhyming verses evoke images of their own: “Soon the summer sun is back / and warms me with its rays. / I rise in rumbling thunderheads / like castles in the haze,” though at times word order seems to have been chosen for rhyme rather than meaning (“In fall I sink into a fog / and blanket chilly fields, / with pumpkins touched by morning frost / the harvest season yields”). Backmatter includes a diagram of the water cycle that introduces and describes each step with solid vocabulary, including “Collection” as a step in the process; “The Science Behind the Poetry,” which unpacks some of the poetic language and phrases; some water activities and explorations; conservation tips; and a list of other books from the publisher about water. Paterson’s full- and double-page–spread illustrations are just as magical as his verse, showing water in its many forms from afar and close up. Few people appear on his pages, but the vast majority of those are people of color.

A lyrical and educational look at the water cycle. (Informational picture book. 4-8)

HELLO WINTER!

A solid addition to Rotner’s seasonal series. Bring on summer.

Rotner follows up her celebrations of spring and autumn with this look at all things winter.

Beginning with the signs that winter is coming—bare trees, shorter days, colder temperatures—Rotner eases readers into the season. People light fires and sing songs on the solstice, trees and plants stop growing, and shadows grow long. Ice starts to form on bodies of water and windows. When the snow flies, the fun begins—bundle up and then build forts, make snowballs and snowmen (with eyebrows!), sled, ski (nordic is pictured), skate, snowshoe, snowboard, drink hot chocolate. Animals adapt to the cold as well. “Birds grow more feathers” (there’s nothing about fluffing and air insulation) and mammals, more hair. They have to search for food, and Rotner discusses how many make or find shelter, slow down, hibernate, or go underground or underwater to stay warm. One page talks about celebrating holidays with lights and decorations. The photos show a lit menorah, an outdoor deciduous tree covered in huge Christmas bulbs, a girl next to a Chinese dragon head, a boy with lit luminarias, and some fireworks. The final spread shows signs of the season’s shift to spring. Rotner’s photos, as always, are a big draw. The children are a marvelous mix of cultures and races, and all show their clear delight with winter.

A solid addition to Rotner’s seasonal series. Bring on summer. (Informational picture book. 4-7)
