Thermochemical teaching experimentation using low-cost materials

Abstract

This work addresses the experimentation in teaching thermochemistry using low-cost materials. The work happened in a school in the municipality of Irituia, Pará, Brazil, with the participation of 58 students from 2° year of high school. Used as thematic workshops methodology divided into three educational moments: the first moment has been initial questioning, where scanned if the prior knowledge of the pupils; in the second time worked if the organization of knowledge, with the clarification of the matter in question; and on the third time, the application of knowledge, when students performed experimental practices demonstrating subject matter studied domain. After the implementation of the practice, discussed issues relevant to the experiment with the intention of obtaining the results of more dynamic and fruitful as regards the subject. The results showed increased participation and interest of students for the content in question, thus confirming the learning in relation to the subject. It was noticed that there was an evolution of thought of students before and after the application of the thematic workshop, confirming that the application of such pedagogical practice is of fundamental importance for the improvement of chemistry teaching in public schools.
