Abstract: This paper explores concepts about air, water and soil pollution that students of grades 7–9 have in Argentina and Puerto Rico. A structured questionnaire was used in the investigation. A quantitative analysis was carried out to characterise the occurrence and frequency of conceptual errors, and to analyse their decrease with an increase in the educational level of the students. The results showed how students perceived abstract and local problems regarding pollution, and the differences owing to their cultural environments. Finally, the results seemed to support the hypothesis about the importance of cognitive stages and their relation with stages of development and evolution with age.
