The Juazeiro (<i>Ziziphus Joazeiro Mart.</i>) and the Formation of Concepts and Parameters in Chemical Technology Education

Abstract

Ranging from the northeast of Brazil to the north of Minas Gerais, in the region of the savanna, the popularly known Juá or Juazeiro (Ziziphus Joazeiro Mart.) is a plant that has great potential medicinal, scientific and economic that can be used in order to contextualize the chemistry teaching that increasingly is becoming fragmented and full of gaps. The aim of this study is to suggest possible concepts and chemistry discipline of content that can be worked by analyzing the properties and benefits of Ziziphus Joazeiro. For it was made a bibliographic review of the plant's properties and their uses can be different and applications in chemistry classroom. There are many chemical concepts that can be worked through juazeiro. In this paper we present some of them such as polarity of the molecules, hydrophilic and hydrophobic substances, antioxidants, solubility, and others that can be studied. It is of great importance the study of plants of a region so threatened as the savanna. This study was the starting so that teachers start to change their way of teaching and find ways to enable student learning takes place in a positive and satisfactory.
