Ensino de química : uma proposta de inovação, adaptação dos modelos atômicos

Abstract

The teaching of chemistry in Brazil at first was only seen in High School, like the current change made in Basic Education, Elementary School received the application of some concepts of chemistry that will serve as a basis for later school years. In the last year of elementary school in Natural Sciences, it brings among the contents, the study of the material world, "The evolution of atomic models". We know that this subject can be very complex when demonstrated only theoretically. a more dynamic education, attributing to it the construction of atomic models, as a tool that facilitates the students' understanding, the proposal in question aims to provide structures of atomic models based on recycled material and cost-effectiveness. from recycled materials, it is about raising awareness about the correct disposal of plastics. By learning the subject studied, the student will be able to make connections with new studies. For this, a didactic sequence was carried out that will help the teacher to consolidate this learning.
