It takes only a cardboard tube to fashion an effective stethoscope. With this simple tool children are introduced to the wonders of the human body's strongest organ. Listening to others' heartbeats opens the door to understanding what the heart is, what it looks like, how it functions and the role it plays in human biology. Using different hands-on exercises, the author demonstrates that every heart is as unique as each individual. An adult heart beats at a slower rate than an infant heart. During the course of the day, an individual's heartbeat varies. Fast or slow, day or night, the heart is always on duty. Readers of all ages will appreciate the charming drawings of multicultural children checking pulses, using stethoscopes and measuring heartbeats after exercise. Younger children may have difficulty understanding the drawings detailing the heart and its function. Backmatter includes extended exercises for healthy hearts and a web site for further information. This is a Stage 2 book in the HarperTrophy "Let's-Read-and-Find-Out Science" series. 2001 (orig. 1968), HarperCollins, , . Ages 5 to 9. Reviewer: Stephanie Farrow
Gr 1-3-A revision of a 1968 book. Keller's illustrations and Showers's text complement one another well, and will give young readers a good introduction to how the heart works. Three simple activities (measuring heart rate, exercising the heart, and making a stethoscope) are easy but effective ways to augment the text. The writing is succinct and clear. The simple line illustrations include a minimum of detail yet they reflect the action and convey different emotions effectively. The illustrations of the structure of the heart are well done, resulting in a good overview for beginning readers.-Christine A.
