You and Your Body, Third Edition

Students explore You and Your Body through fourteen hands-on activities and the Delta Science Reader. First your class will examine the skeletal system, identifying major bones and joints. Next they replicate the arm's muscle coordination and measure reaction time. They model the pumping action of the heart, calculate lung capacity, and investigate respiration. They find out why we have different types of teeth and how to keep them healthy. Skin is exposed as a versatile body part, not only for cooling and protecting us, but also for sensing our environment. Students discover how the five senses work to perceive and evaluate incoming information. Finally, because the body runs on fuel, students test foods for nutrient content and practice reading nutrition labels.

In the Delta Science Reader You and Your Body, students read about how cells "the body's building blocks" make up tissues, organs, and organ systems. Then students explore some of the body's main systems; skeletal, muscular, circulatory, respiratory, digestive, and nervous. The book also touches briefly on the endocrine, immune, reproductive, and excretory systems. Biographies of two medical pioneers, Dr. Charles Drew and Dr. Elizabeth Blackwell, are included. The book concludes with a look at how reflexes work.
