THE SECRET CODE INSIDE YOU

As they begin their exploration of the concept of DNA, the youngest listeners will be drawn in with questions featuring fun animals and text with internal and end rhymes, alliteration, and puns. “Why aren’t you finny like a fish, / or grinny like a shark? / Why can’t you catch flies with your tongue, / or / see / things / in / the / dark?” Describing DNA as “twisted ladders, or tiny, twirling noodles” creates accessible concrete images for children. The science ramps up for slightly older readers and discusses how personal traits like height or the size of a child’s nose, ears, or hands are determined by the DNA that parents and grandparents share with their children. Definitions and explanations of key vocabulary like genes and chromosomes are clear, but the rhyming format creates the occasional awkward phrase. Dynamic and eye-catching illustrations on later pages emphasize the difference between genetic coding and each person’s unique choices. “[DNA] makes the color of your eyes, / but YOU choose where to look: / at butterflies or sunset skies, / or even at this book.” Personal choice also determines how someone uses their muscles and chooses an occupation. For older readers or the more science curious, the backmatter is full of DNA facts and explanations, URLs to child-friendly websites, and a well-designed and -explained experiment to extract DNA from a banana.

A solid introduction to a complex topic.
