Neste trabalho, é proposta uma experiência didática com o objetivo de avaliar e diferenciar, de forma simples e clara, duas propriedades intrínsecas da matéria que formam parte do vocabulário cotidiano, a viscosidade e a densidade. Para tanto, foram escolhidos três líquidos de uso doméstico, a saber: solução de sacarose, detergente biodegradável e óleo vegetal de soja. A análise dos resultados coloca em evidência a falta de uma relação de proporcionalidade entre essas propriedades.
In this work, a teaching experience is proposed in order to evaluate and differentiate, in a simple and clear way, two intrinsic properties of matter that make part of daily vocabulary, viscosity and density. To this end, three liquids for domestic use have been chosen, namely saccharose solution, biodegradable detergent and vegetal soybean oil. The results analysis evidences the lack of a proportional relationship among these properties.
