Item Proposta de um jogo didático intitulado Trilha do Fogo para o ensino de reação de combustão(2021-03-09) Viana, Eugênio Santana; Batinga, Verônica Tavares Santos; http://lattes.cnpq.br/7759044153725982; http://lattes.cnpq.br/1530132254676601This presents the development of a Didactic Game entitled "Fire trail" to approach the content of Combustion Reactions, aimed at students of the 1st year of high school, due to the need to plan and introduce ludic didactic strategies in Chemistry classes. This game consists of a questionnaire that aims to diagnose students' previous conceptions about combustion reaction and the steps that make up the didactic game based on theoretical criteria established in the literature, such as: cooperative, board and card games, rules set, puzzle, quiz game, accessories and roll and move. The aim of this game is to provide effective participation and student engagement, interaction between student-students and student-teacher, and the mediation of the teacher in the different moves for the collective construction of the chemical knowledge of combustion reaction.Item Influência da taxa de aquecimento na produção do carvão da madeira de Eucalyptus spp(2019-07-12) Interaminense, Pedro Paulo Barros; Braz, Rafael Leite; http://lattes.cnpq.br/7332493832361305; http://lattes.cnpq.br/7774231489365848This work aims to evaluate two carbonization marches and the fresh material collected in a Eucalyptus stand, located in Araripina - PE, in the northeastern backlands, using several clones who being homogenized to evaluate the practices. The Eucalyptus' samples were transformed into chips and underwent a drying process in an oven regulated at 65ºC ± 5ºC for 48-72 hours, until they reached constant weight, obtaining the moisture content and bulk density. Part of the biomass was intended for immediate chemical analysis and to estimate the superior calorific value, and the rest was used to the carbonization process. The gravimetric yield, immediate chemical analysis, and estimation of the superior calorific value of the charcoal produced were determined. Regarding the immediate chemistry analysis, it was possible to observe the reduction of volatile material contents and increase of fixed carbon after the carbonization process. The estimated calorific value was 4357.35 kcal.kg-1 for the fresh sample and 7220.28 kcal.kg-1 for the first march and the second march, related to the charcoal, was 7265.15 kcal.kg-1. Thereby, the second gear is better to use as charcoal because it has a shorter carbonization time and it has the same quality when compared to the first gear for the variables used.
