This fourth grade curriculum guide for health education follows the Duval County Public Schools (Jacksonville, Florida) comprehensive program for K-12 that aims to help students gain an intelligent understanding of health as a unity of physical, mental, and social well-being. The guide deals with three primary ideas: (1) the human body has a basic structure and function; (2) development in individuals may be altered by factors in the environment; and (3) the quality of human health may be improved by the cooperative efforts of men and women. Each lesson plan includes concepts/skills (to be taught), test references, estimated teaching time, objectives, instructional materials, teaching procedures, evaluation procedures, and enrichment and reinforcement activities.
