Inside the Heart

With short sentences, a wealth of clearly labeled diagrams, “Fast Fact” boxes, and useful hands-on activities, this volume explains the workings of the human heart. The “How to Do It” activities, in particular, go a long way toward making advanced concepts approachable; in one example, illustrated step-by-step instructions show children how to re-create the pumping action of the aorta with a jar, a balloon, and other common household objects. A handsome, retro color scheme (tangerine, brown, mint green, and teal) gives the book visual cohesion, and the use of a shadowed font make the chapter titles pop. Includes a note to adults and a glossary.
