Do Termoscópio ao Termômetro: a experimentação no ensino de física ao alcance de todos

Abstract

This study presents the construction of a handmade thermometer as an accessible didactic tool for teaching Physics, focusing on Thermology content. The proposal aims to overcome challenges in traditional education, such as concept abstraction and lack of hands-on experimentation. Using simple and low-cost materials, including ampoule bottles, cooking oil, and straws, a functional device was developed to demonstrate thermal expansion in practice. The thermometer was calibrated based on the Celsius scale, and data analysis revealed thermal hysteresis behavior, typical of fluids with low thermal conductivity. This quantitative, experimental, and descriptive research shows that accessible experimentation can foster a more inclusive, interactive, and meaningful learning process, encouraging critical thinking and active student engagement
