\u201cYou have to believe that it is possible.\u201d This is the mantra that B\u00e1rbara Rodrigues, a chemistry teacher at Escola Estadual Professor Sebasti\u00e3o de Oliveira Rocha<\/a>, in S\u00e3o Carlos (SP), repeats to herself.<\/p>\n\n\n\n

She believes that the transformation of education lies in encouraging students to think critically<\/a> and have the space and conditions to build their own responses to local problems<\/a>. \u201cThe science curriculum<\/a> needs to be lived in practice, answering questions they identify in everyday life,\u201d she explains.<\/p>\n\n\n\n

Mediating<\/strong> a Youth Science Club called Tecnologia Escolar Sustent\u00e1vel Ligada ao Ardu\u00edno (Sustainable School Technology Connected to the Arduino \u2013 TESLA)<\/a>, and with the support of the biology teacher Isabel Cristina Santana Kakuda, B\u00e1rbara encouraged a group of ten students to build an anaerobic digester at school. Inspired by another school project, which calculated the waste in school lunches, the young people and the teacher decided to advance the discussion about food leftovers and its effects on the environment. Even having managed to significantly reduce the rates of food disposal, there were still leftovers that could be reused and transformed. \u201cTogether, we studied several alternatives for reuse and arrived at the proposal to build a biodigester\u201d, explains B\u00e1rbara.<\/p>\n\n\n\n

For the construction of the equipment, it was necessary to study concepts of chemistry and biology linked to the decomposition of organic matter and to research conceptual and technical paths to respond to the identified demand. For this purpose the teacher presented a set of academic and didactic references to the class, inviting them to draw their hypotheses. In a dynamic that included meeting moments, individual and collective study of the class, B\u00e1rbara drew up a research and experimentation plan with the young people until arriving at the construction of the prototype<\/a>.<\/p>\n <\/div>\n
