Ages 6-9

Once Wanda found the stars, they’re all she ever wanted. Despite childhood diabetes and antipathy toward school, curious and strong-willed Wanda set her sights on college to study astronomy. But when diabetes took her sight, she needed coping mechanisms and creative thinking to continue pursuing her goals. With the aid of recorded radio waves—sonification—Wanda was able to “hear a path to the sky” and continue to explore the stars in new and exciting ways.

In this picture book biography, Amy Hansen follows the story of her friend, colleague, and co-author Wanda Daíz Merced from a childhood in Puerto Rico to a career researching and teaching around the world. The thoughtful text focuses on Daíz Merced’s determination and her doubts, allowing readers to see her vulnerability and witness her triumph in overcoming obstacles like wayfinding in a new place or proving her methods to the scientific community. Spanish quotations, vocabulary, and translations are cleverly woven through the text, especially during scenes set in Puerto Rico, bringing her heritage to vivid life. The lush digital illustrations, in a saturated, blue-dominated color scheme, feature a fluid combination of diverse people and sound-images with cosmic flourishes to complement the astral theme and role of sound in her life. A combination of small vignettes and double-page spreads lets the reader into both intimate moments and large-scale events in her life. Robust backmatter includes a glossary and Spanish translations, author and scientific notes, and extensive lists of sources and resources. As an advocate for STEM education and disability inclusion, Wanda Daíz Merced serves as a champion for diversity in the sciences, while her adaptability and perseverance make her a powerful role model for everyone.

How It Works: A Review of Bounce!: A Scientific History of Rubber

Used for everything from bike tires to raincoats, rubber plays a major role in things springy, stretchy and bouncy in ours daily lives. Follow its history from the discovery by indigenous Central American tribes (who farmed natural rubber latex from local plants), adoption by Europeans (imagine the difference when their soccer balls could bounce!), and the evolution in its usefulness into the multipurpose substance we can’t live without today. Part narrative nonfiction and part traditional nonfiction, Bounce combines a fascinating story of invention with “The Science!” interjections that explain the how or why of a narrative detail (what is it that makes rubber sink or float?).

Award-winning nonfiction author and former basketball-player (who appreciates a bouncy ball more?), Sarah Albee explores the history and science behind a very common part of everyday life. With a panel of expert readers—chemists, materials scientists, and engineers—Albee dives deep into both the story and the scholarship with accessible language and delightful facts. The extensive and respectful backmatter includes sections on tribal naming preferences, acknowledgement of the troubling issues of slavery and the environmental impact of rubber production, a timeline that dives deeper into some details from the narrative, and a thorough bibliography and source notes. Intricate yet fluid pen, ink, and watercolor illustrations connect closely to the text descriptions with detailed images of the action, movement in the line work, and expressive faces. Eileen Ryan Ewan uses color to help show the passage of time, moving from muted and historically accurate colors to more vibrant shades in the modern spreads. This engaging and fact-filled picture book would be a perfect accompaniment to introductory science lessons on the properties of matter or chemistry in upper elementary school or for the budding scientists in any library.
