Globo negro: uma proposta de sequência de ensino para processos de propagação de calor e radiação térmica

Abstract

This product is a proposal for a didactic sequence as a potentially significant material for processes of heat propagation and thermal radiation, applied to the second year of high school, using a technical experiment, known as Vernon's Globe, black globe, globe thermometer or globe-thermometer, which indicates the Radiant Thermal Load (RTL - Stefan-Boltzman Law) and the Mean Radiant Temperature (MRT). The data analysis process together with the students is based on Ausubel's Meaningful Learning Theory and on Science Teaching by Research by Ana Maria Pessoa Carvalho. Initially, the execution of the product would be in face-to-face teaching, but in the face of the COVID-19 pandemic, adaptations were made to the remote model, seeking to preserve interaction between the student and the experiment and the characteristics of Significant Research and Learning. Thus, it is expected that the results of this activity facilitate students' understanding of the concepts of Temperature and Black Body, contributing to the learning of Thermology, with the prospect of being considered a substantial innovation in the teaching process.
