This interactive Web site from the Centers for Disease Control and Prevention encourages kids to be healthy in body and mind. The activities are designed to complement the type of health and science lessons that are currently taught in many middle school and high school classrooms. The Adobe Acrobat (.pdf) lesson plans include a pre-assessment to help teachers determine which of the activities are most appropriate for their students, and National Education Standards are identified where applicable. Students will also enjoy this Web site with its variety of activities, games, and quizzes (many of which can also be printed).
