Agrochemicals known as pesticides, come from various chemical components, and have raised questions about their use, as many of these compounds accumulate in our bodies, causing cancer, in addition to causing serious environmental problems. Thinking of a perspective of making students aware of the chemistry discipline in high school at a public school in Paraiba, Brazil, a didactic sequence was developed addressing the chemical concepts related to the use of pesticides and the environmental problems caused. In general, students had little knowledge about the serious risks of discriminating the use of pesticides. A questionnaire was applied as an evaluative method, where the results were satisfactory: the students were able to understand that the excesses of pesticides in food can bring serious health risks, in addition to contaminating soils and water tables because some pesticides may contain the presence of heavy metals.
