The goals of this study were to diagnose the structure of adolescents' social representation about aids and to examine the relationship of that representation with students' scientific knowledge about aids. A total of 262 students from a public high school in Florianópolis (Brazil) took part in the study. A self-applied questionnaire, and a scientific knowledge test about HIV/aids were used. Structural analyses employing the software Evocation and Similitude 2000 were carried on. Data revealed that the representation of aids is composed by the central elements: disease, death, fear, suffering and prejudice, which were also found in previous studies; joined by two new elements: prevention and responsibility. More than half of the students (55%) was not considered scientifically well informed about HIV/aids. Aids prevention power, characteristically pragmatic, can be verified in the mentality of students, insofar as they emphasize the representation's affective dimension, and less the biomedical and scientific knowledge about the disease.
