Contaminação invisível - uma proposta para divulgação e visibilidade e visibilidade aos microplásticos

Abstract

Solutions that are microplastics derived from commercial microplastics, or even by industry, by some plastic fragments caused by higher tempering and plastic, chemical and biological reduction. As well as their material, microplastics also have distinct physical properties such as density, for example, which can primarily determine the dynamics of the position of these particles in the environment. From this, it is possible to find that we can find all microplastic particles of water in an ambient column. Therefore, microplastics can contaminate both the biota present in the water column and in the bottom of ecosystems. In order to contribute to the environmental sciences for teaching the water column for the microplastic work environment and for the project as the auxiliary product for water in water environments, water packs for the environment of low density polypropylene (PP) and polyethylene terephthalate (PET) with high relative density. In order to validate the application of the product as a didactic tool, the study was applied to two classes of the 7th year of elementary school. The class was an applied theoretical class and the second class was on the MP theme, and the second class was an applied class, the model and the subject. After analyzing the question answered by the classes, it was observed that when the model was presented in the class, there was a significant difference in the proportion of correct answers for six from the eight questions.This indicated a positive relationship between the use of models as a tool to aid in the teaching of Environmental Sciences.
