The homemade soap production: a millenary pratice that stimulates technological innovation among students

Abstract

The process of producing homemade soap using leftover oils from frying makes possible the teaching-learning process of various contents of Chemistry, articulating the theory and practical through experimentation. The aim of this work is present the technological product created by a student and their workgroup during a project with the theme of the production of fragrant homemade soap. The soap mixer was developed within the scope of research developed in a professional master’s degree, during a qualitative intervention research, carried out in the first grade of the New High School of the State Education Network in the state of Espírito Santo, Brazil. This intervention had a Project-Based Learning (PBL) which teaching methodology, focused on Science, Technology, Society and Environment (STSE – CTSA in Portuguese) Although soap production is common, the need for assistance in the soap mixing process encouraged the development of a technological product, developed from a recyclable and low-cost materials. This action demonstrates that the problematic proposition by PBL focusing on STSE provided a favorable scenario for the development of skills set in students, additionally this demonstrates that innovation can emerge from routine activities, and can contribute to the efficiency of production processes. Furthermore, the use of recyclable materials in the manufacturing process of the soap whisk reinforces the commitment to sustainability and economy.
