(2) 4-6 Illustrated by William Goldsmith. This creatively rendered biography-in-comics, with Muir's imagined voice as narrator, is filled with the naturalist's adventures, from his childhood in Scotland to his pioneering conservation work and formation of America's National Parks. Illustrator Goldsmith's Muir is a feisty character, portrayed in loose pencil sketches with one or two accent colors. Vibrant spreads in the chapter transitions and interludes capture the stunning landscapes in which Muir found his purpose. Timeline. Glos.

(2) K-3 Illustrated by Steven Salerno. Fascinated by the natural world's many colors, Edwin Binney developed eight different colors of nontoxic crayons at his company in June 1903; they were an instant hit and are still made today. Whenever the text mentions a color, the word is set in bold for easy recognition by children. Salerno's dynamic spreads aptly burst with a variety of colors. Occasional helpful sidebars provide further explanations, particularly about the Crayola invention process. Bib.

(3) 4-6 Illustrated by Valpuri Kerttula. Where did your breakfast banana come from? How are your jeans made? How does your house have electricity? Each two-page spread illuminates these and other "journeys" with numbered steps for each process. Technologies such as cellphones, the internet, and--yes--indoor plumbing are covered. A fascinating behind-the-scenes look at items and systems readers may take for granted. Back matter would have increased the educational value.

(2) YA Ada Byron Lovelace followed nineteenth-century conventions by marrying and bearing children yet still pursued scientific interests. Her friend Charles Babbage produced a mechanical tabulation machine, which Lovelace defined as a computer prototype; her resulting algorithm is often considered the first computer program. McCully clearly and systematically outlines mathematical concepts while painting Lovelace's life as one characterized both by spurts of brilliance and many challenges. Archival illustrations and photographs appear throughout. Bib., glos., ind.

(4) K-3 Illustrated by Brett Helquist. This look at young Les Paul, the father of the solid-body electric guitar, capably explains the mechanics behind the boy's inventions--a little too capably, as short shrift is given to interiority, although the retro-flavored oil paintings tease out the human element. This book is best suited for readers (including adults) who are already besotted with the rock guitar sound. Bib.

(2) K-3 Illustrated by Katy Wu. WWII-era film star Hedy Lamarr (1914–2000) was also an inventor whose "brain overflowed with idea after idea." Though Lamarr's technology is widely used in today's electronics, it took decades for her work to be acknowledged. Well-chosen quotes reveal Lamarr's frustration with people's assumptions about her intelligence based on her "pretty face." Approachable digital illustrations ably portray Lamarr in glitz-and-glam-Hollywood mode and at her inventing table. Reading list, timeline. Bib.

(4) K-3 Illustrated by Jennifer Oxley. Fair-skinned Melia loves inventing; brown-skinned neighbor Jo is always singing, dancing, and making art. However, this unlikely pair (perhaps inspired by Amelia Earhart and Josephine Baker?) learn that they can "create more super-cool stuff together than either could create alone." Bright, cartoony illustrations featuring orange, lime, and purple complement the motivational (if message-y) text. Back matter includes craft instructions and a STEAM-encouraging note.

(3) K-3 Illustrated by Yasmeen Ismail. Because of giraffe Noodle's loud snoring, Sophia's new pet (her birthday gift in One Word from Sophia) may be exiled from her quirky family. Approaching the problem scientifically, inquisitive Sophia consults an acoustical engineer, then experiments, fails, and finally builds a wacky "snore transformer" that turns Noodles's snoring into "a sweet giraffian lullaby." Loose, Raschka-esque watercolor and colored-pencil illustrations complement the story's playful language. Glos.

(3) 1-3 Questioneers series. Inspired by Beaty and Roberts's picture-book collaborations (Rosie Revere, Engineer and others), this series-opening chapter book ticks many boxes: STEAM engagement, growth mindset, strong girls, diversity, and intergenerational learning. Zany as ever in the stylized illustrations, Rosie and friends must invent a painting aid for one of elderly Aunt Rose's spitfire friends. Sturdily made and stylishly designed, the book is a solid addition to collections.

With bright colors, dynamic panels, a wacky sci-fi plot, and lovable animal characters, this graphic novel should engage young readers.
