A experimentação investigativa no ensino de cinética química

Abstract

This work aims to present a proposal for an investigative class for the teaching of Chemical Kinetics, in the context of Basic Education. For this, an experimental class of an investigative nature was designed for students in the 2nd year of high school, on the factors that influence the rate of development of a chemical reaction, based on the experiment 'iodine clock'. From the perspective of action-research, we developed the class in five classes of a state public school, in the city of Ituiutaba/MG. We realized that the proposal developed and presented is a possibility to actively insert students in the learning process through contextualized activities capable of fostering their knowledge about Chemical Kinetics. The research made it possible both to observe the daily life of public school teachers and to materialize the student-teacher, student-student interaction in an investigative experimental class.
