Experimentação no Ensino de Física - Dilatação Térmica

Abstract

Faced with the observation of high school students' lack of interest in the natural sciences and especially Physics, many report that this discouragement is due to the difficulty of dealing with mathematics, a fundamental tool for quantitative studies of this science. As an alternative, the experimental approach has been used to mitigate the difficulty in understanding physical phenomena, in addition to instigating high school students' interest in natural sciences. In this investigation we analyze the possibilities of using the linear dilatometer as an instrument in the teaching of thermometry, for this we will repeat the experiment of dilation of three different metals (copper, brass and steel) and we will measure the values of the coefficients of linear dilation comparing with the values of the literature , we will assess whether the aforementioned instrument can be used effectively as a contextualization tool and, based on this procedure, analyze the influence of this activity on the students' teaching-learning process
