Awareness activities pertaining to cancer and cardiovascular disease are presented as a supplement for high school science classes. The exercises can be used to enrich units of study dealing with the circulatory system, the cell, or human diseases. Eight activities deal with the following topics: (1) cardiovascular disease risk factors; (2) cardiovascular fitness; (3) cardiovascular responses (blood pressure and heart rate); (4) the incidence of cancer correlated with age; (5) the incidence of cancer correlated with life-style factors; (6) clues to cancer prevention; (7) the incidence, diagnosis, and prognosis of cancer; and (8) an overview of cancer. Most of the activities can be completed in a 55-minute class period and permit teacher-student question and discussion time. The activity providing an overview of cancer requires more than one class period to allow for out-of-class research. Suggested answers and conclusions for each activity and a list of pamphlets on cancer awareness with availability information are included. This document is part of a collection of materials from the Iowa Area Education Agency 7 Teacher Center project. (JW)
