GOMES, Luciana Maria de Jesus Baptista; DIONYSIO, Luis Gustavo Magro  and  MESSEDER, Jorge Cardoso. Analysis of household cleaning product labels to discuss everyday chemistry with students. Educ. quím [online]. 2015, vol.26, n.1, pp.21-25. ISSN 0187-893X.

Chemistry is present in the daily students' life through the use of products at home, such as household cleaning products. Still, it is hard for students to perceive it vividly in their lives, because within syllabi, chemistry is reduced to formulas, names and reactions, opening a gap between school knowledge and their reality. That is why this work describes a demo-investigative activity, conducting analysis of household cleaning product labels, with the goal of helping the student to reaffirm and / or reframe their knowledge about them and their relation to safety, health, environment, science and technology. Conducted in two schools with very different economic realities, there were perceived similarities in the perception of the students and teacher's ability to act as mediator between school knowledge and students' knowledge so they reframe chemistry in their own lives.

Keywords : demo-investigative activity; STS; situated learning.
