Enabling teachers to present a detailed unit on smoking is an objective of this curriculum guide. It organizes information which, if made a relevant part of the student's experience, attempts to help him effectively resist the pressures to begin smoking. Seventeen units, arranged in sequential order, cover cardiovascular and respiratory systems, statistical data, lung cancer, physiological changes, social influences, aesthetic features, economics, advertising, and moral issues. Repetition and over-lapping of content is intended to reinforce commitments resulting from previous instruction. Behavioral objectives, related concepts, content material, experiences or suggested learning activities, and resources and materials are arranged in column form for each unit. Opposite this information, appropriate grade level use is indicated; elementary, designating grades 5 and/or 6; junior, specifically for grade 7 but including grades 8 and 9; and senior, primarily for grade 10 but also grades 11 and 12. Minimum time recommended for implementation of the units is five periods for elementary grades and three periods for upper grades. Appended material includes a checklist of facts related to cigarette smoking and health; vocabulary or terms; suggestions for smoking education in grades 1-4; scientific and social experiments; and suggestions for integrating smoking education with other subjects.
