Obtaintion of magnetic nanoparticles using everyday materials: synthesis, characterization and didactic approach for high school

Abstract

In this work, an experimental practice is presented using low-cost materials, to obtain magnetic nanoparticles and also a didactic proposal was applied about the theme Nanoscience and Nanotechnology, based on a CTSA approach. The nanoparticles were characterized by light scattering and scanning electron microscopy. The proposal was composed of an experimental activity, discussions about the result of the characterization and introduced the themes Nanoscience and Nanotechnology and its applications. The results of the characterization suggest that the used methodology to obtain the nanoparticles was efficient for didactic purposes and the didactic proposal provided learning of scientific content and its applications.
