AÇÚCAR MASCAVO E ENSINO DE CIÊNCIAS: UMA PROPOSTA INTERDISCIPLINAR

The state of Paraíba has an important role in shaping the culture and richness of the Brazilian people dating from the colonial period with the construction of the sugar cane plantations in the area of forest and swamp Paraíba. This view of our history provides exploration of possibilities content from different fields of knowledge. An appropriate approach makes it possible to develop an interdisciplinary teaching strategy or even multidisciplinary. One of the first products produced from sugar cane after the honey is brown sugar, a richer product nutritionally than refined sugar. We aim to develop the theme in a high school class in view of the understanding of how scientific and technological knowledge has influenced social relations in colonial Brazil, comparing the mode of production for different types of sugar (brown sugar, demerara and crystal), understanding how industrial revolution influenced the production and life in seventeenth-century mills, why sugarcane is a raw material for sugar production in our country, etc. The methodology used in this work began with the filtration and cooking broth obtained in free smitten City Cuité. Evaporated and cook the broth until the removal of at least 75% of the water and turn it into a concentrated syrup. After cooking produce a thick paste that was macerated to be cooled to give brown sugar. In the process we do not have the crystallization because the use of a centrifuge would be required. In the first stage we were successful with getting the sugar and we are planning together with teachers of basic education in a public school Cuité / PB, the didactic sequences addition to the choice of the target audience to the experience of the second stage of the project. We identified in the chemical area some content that can be developed around theme as separation of mixtures (simple distillation, fractional distillation and crystallization), fermentation (alcohol and rum production); in history, captaincies, slave labor and the capitalist mode of production, the role of technology for the production of sugar; in biology, biotechnology with the role of microorganisms in the fermentation process and the importance of geography and climate of the relief for the production of sugarcane, etc. We conclude that the issue is a good generator theme option for teaching chemistry and science, and allows the contribution of other areas of knowledge in building a broader understanding of the process of getting a lot this product to the tables of the students themselves and has a historical and geographical reference in a neighboring region to Curimataú, the Paraiba swamp.
