Construção de modelos para ilustração de estruturas moleculares em aulas de química

Abstract

This paper describes the construction of a kit of molecular model for illustration of molecular structure in chemical class using cheap materials. The atoms were represented by plastic spheres and the bonds between the atoms were made from plastic straws which were cut in the required length using a scale of 1.6 cm corresponding to 100 pm. Examples of adaptations made in this kit for didactical application are given.
