Investigative experimentation - the use of alternative materials to explore methods of mixture separation from case studies in high school

Abstract

The implementation of investigative experimental activities in teaching chemistry is seen as a facilitator in the teaching learning process, because some topics, such as methods of mixture separation are little explored due to the lack of laboratories with materials and adequate equipment in public high schools. In this conception, we tried to work on mixture separation using the case study method and experimental activities using alternative materials. It can be seen that the activity allows students to construct their own knowledge, developing autonomy and identity. Besides the inclusion of experimental activities in the school space, without the need for glassware or specific equipment.
