DIDACTIC SEQUENCE FOR THE PROMOTION OF PRACTICAL AND MULTIDISCIPLINARY STUDY WITH ACCESSIBLE MATERIALS

Innovation and multidisciplinarity are the way to accelerate improvements in education, as well as the search for contextualized content. The multidisciplinarity between chemistry and Biology, allows to explore various contents, one of them is the environment. Works that offer alternatives to simpler experiments are of great help professors. In this context, this study suggests a didactic sequence using easily accessible materials to address chemical and Microbiological concepts of soil. The proposal is aimed at high school students and early undergraduate students. The contents were: hydrogen potentials (pH), mixture separation methods, soil liquid and gas phases and soil microbial population extraction involving bacterial DNA. Thus, the work shows a low cost alternative for the teaching of concepts related to soil, being a contextualized, multidisciplinary, dynamic and attractive proposal.
