THE DIGESTIVE SYSTEM

A TOUR THROUGH YOUR GUTS

From the Science Comics series

An illustrated adventure through the human digestive system.

The subtitle says it all—no organ or, seemingly, molecule goes unexplored, from the oral cavity all the way to the rectum. The protagonist is a bacterium in the oral cavity named E who accidentally leaves the comfort of its natural habitat (where some 50 billion to 100 billion other bacteria reside) when it’s swallowed along with a bolus (or blob of chewed food—one of many vocabulary words defined in context and in a closing glossary). E meets new bacteria, enzymes, and sentient organs along the way who explain their roles in the digestive tract. “My dominion,” explains H. pylori, “is the thick gastric mucosa, or mucous membrane.” As E moves through the digestive system, a diagram that appears periodically continues to grow. Viola’s text clarifies the concepts with the help of Ristaino’s illustrations, which also provide humor, and much of what is introduced is reiterated at other points in the graphic novel, aiding retention. While Viola works hard to break down information, he still packs a lot in: “Saliva contains an enzyme called amylase. Amylase breaks down starch, a complex carbohydrate, into simple sugars….And some saliva carries an enzyme called lipase that starts breaking down triglycerides.” Magic School Bus graduates ready for a busy, heavy informational load will find this just the ticket. The backmatter also includes brief introductions to the digestive systems of cats, dogs, whales, cows, birds, and cockroaches.

A fun and challenging introduction. (Graphic nonfiction. 9-14)

Contentwise, an arbitrary assortment…but sure to draw fans of comics, of science, or of both.

FLASH FACTS

Flash, Batman, and other characters from the DC Comics universe tackle supervillains and STEM-related topics and sometimes, both.

Credited to 20 writers and illustrators in various combinations, the 10 episodes invite readers to tag along as Mera and Aquaman visit oceanic zones from epipelagic to hadalpelagic; Supergirl helps a young scholar pick a science-project topic by taking her on a tour of the solar system; and Swamp Thing lends Poison Ivy a hand to describe how DNA works (later joining Swamp Kid to scuttle a climate-altering scheme by Arcane). In other episodes, various costumed creations explain the ins and outs of diverse large- and small-scale phenomena, including electricity, atomic structure, forensic techniques, 3-D printing, and the lactate threshold. Presumably on the supposition that the characters will be more familiar to readers than the science, the minilectures tend to start from simple basics, but the figures are mostly both redrawn to look more childlike than in the comics and identified only in passing. Drawing styles and page designs differ from chapter to chapter but not enough to interrupt overall visual unity and flow—and the cast is sufficiently diverse to include roles for superheroes (and villains) of color like Cyborg, Kid Flash, and the Latina Green Lantern, Jessica Cruz. Appended lists of websites and science-based YouTube channels, plus instructions for homespun activities related to each episode, point inspired STEM-winders toward further discoveries.

A splendid volume for young adventurers.

SURVIVOR KID

A PRACTICAL GUIDE TO WILDERNESS SURVIVAL

Based on her work with middle-school students, Long offers lessons on how to stay healthy and out of trouble while awaiting rescue, the same lessons taught to adults in her survival classes.

Her matter-of-fact, no-nonsense tone will play well with young readers, and the clear writing style is appropriate to the content. The engaging guide covers everything from building shelters to avoiding pigs and javelinas. With subjects like kissing bugs, scorpions, snow blindness and “How going to the bathroom can attract bears and mountain lions,” the volume invites browsing as much as studying. The information offered is sometimes obvious: “If you find yourself facing an alligator, get away from it”; sometime humorous: Raccoons will “fight with your dog, steal all your food, then climb up a tree and call you bad names in raccoon language”; and sometimes not comforting: “When alligators attack on land, they usually make one grab at you; if they miss, you are usually safe.” But when survival is at stake, the more information the better, especially when leavened with some wit. An excellent bibliography will lead young readers to a host of fascinating websites, and 150 clipart-style line drawings complement the text.

A splendid volume for young adventurers. (index not seen) (Nonfiction. 9-14)
