This article describes a Problem-Based Learning (PBL) experience that taught organophosphorus pesticides chemistry, its human health effects and acetylcholinesterase assay to secondary students. The teaching process was based on a real intoxication case and ended with students' activities report presentation. The apparent lack of teacher reference and inexistence of a curriculum based on a strict textbook in which PBL is based on leads inexperienced students to insecurity and the idea that teachers are not doing there jobs. One way to minimize this situation is to use real cases in other to interest students as stakeholders of central problem solution.
