Divulgação Científica da Química dos Extratos Vegetais no Combate ao Mosquito Aedes aegypti

Abstract

The difficulty in learning Chemistry in higher education is a challenge faced by many students, especially due to the lack of contextualization of theoretical content. To overcome this barrier, the creation of an educational booklet appears as an innovativeteaching strategy, aiming to connect the teaching of Chemistry with the fight against disease-transmitting mosquitoes and the extraction of plant extracts. The present work aims to develop teaching material that assists in teaching through contextualization with the theme of combating the Aedes aegypti mosquito. For this, plant extracts were extracted from the Azadirachta indica plant, using different extraction methods, in order to verify its efficiency as a larvicide and use it as a basis for teaching essential scientific concepts for Chemistry. Thus, different efficiencies were obtained based on the experimental procedure used, which was related to the properties of the identified compounds, providing relevant information for the application of these concepts in teaching. Therefore, the construction of the booklet proved to be a tool to facilitate the learning of Chemistry, providing an interdisciplinary approach that connects theory and practice. Furthermore, it is expected that this teaching resource will contribute to raising students' awareness of the importance of Chemistry in solving environmental and health problems, reinforcing its role in society
