It's no secret that America's youth are now more out of shape than ever before. Study after study documents the sad saga of childhood obesity. Quick-fix remedies such as "Atkins for Kids" and child-friendly aerobics classes are proliferating. There are fat camps for kids and low-fat "candy." Still, an inescapable fact remains: As a nation, and particularly among children, Americans are becoming too heavy. Educators are on the front line of dealing with this phenomenon. Most know why it's occurring; it's the "What can I do about it?" that is the frustrating part. These authors describe how, in an attempt to counteract this disturbing trend, they launched a program designed to inform the youngest students of the lifetime benefits of health eating, getting enough exercise, and maintaining a healthy heart and body. "The Healthy K Club," a joint effort among the Physical Education teacher, the Science Lab teacher, and the kindergarten students, is a six-week multidisciplinary program that encompasses a wide range of skills. In addition to physical skills, it includes lessons and activities on nutrition, fitness, and age-appropriate anatomy. (Contains 4 photographs.)
