Demonstre em aula: gotas que inflamam uma abordagem construtivista

Abstract

Este artigo propõe a execução de uma intrigante demonstração para ser apresentada em sala de aula, relacionada com a liquefação de oxigênio existente no ar sobre uma superfície resfriada com nitrogênio líquido. Devido a trabalhar com o inusitado, a demonstração é adequada para ser utilizada com uma abordagem construtivista, de forma que os alunos, baseados nos conhecimentos que possuem, sejam estimulados a formular hipóteses, analisá-las e discuti-las para, finalmente, chegar numa explicação correta do fenômeno.
