Chemistry in high school having the ‘detergent’ as a motivating

The present work was developed with the objective of associating the teaching of some concepts of chemistry with the daily routine of High School students. The chosen subject was “detergents” because this product has taken part in the daily lives of people for some years now. Due to the presence of a tensor active agent, phosphates and other substances in their composition, these products have caused some damage to the environment. Starting by the motivating topic “detergents” and with the building of a conceptual map, it was possible to cover the concepts of hydrogen bonds, surface tension, van der Waals bonds, solubility and also the question of biodegradability of chemical products in the environment
