This curriculum guide for teaching about blood donation was prepared to improve school-community participation in the New York City Blood Donor Program. It contains plans for five lessons on the following topics: (1) the nature of blood; (2) blood and technology--modern-day advances; (3) blood and your personal health; (4) the blood donor as good citizen; and (5) increasing blood donations. Each lesson contains background notes for the teacher. Teaching strategies are broken into steps that are organized according to performance objectives, materials necessary, development of topic, and summary; and include student worksheets. The materials in this guide are useful in several subject areas, such as health education, health careers, and social studies. (PS)
