Nine activities are included in this booklet to help children be "germ smart" help children in kindergarten through third grade be "germ smart" and understand and remember basic information about disease and disease prevention. Age-appropriate examples and a highly interactive, visual format are used to help students understand what germs are, how the body fights disease and infections, and how one's behaviors can help or hurt the body's immune system. Activities are designed to help children learn how germs spread from person to person and to understand which diseases are easy or hard to "catch." Students will also learn what steps to take to help them stay healthy: for example, getting enough sleep, eating right, washing hands, and other basic good health strategies. (NB)
