Resumo: | In this paper, we propose the development and use of an experimental classroom activity that simulates infrared motion sensors, commonly used to control the interior lighting of buildings and, consequently, to save energy. The aim of this experiment is to facilitate and contextualize the understanding of the concepts of 'transmitter' and 'receptor' by using a circuit involving infrared. This activity looks at issues such as the built-in obsolescence of electronic devices in order to raise pupils' awareness of the environmental and social impact of such issues. |

O propósito desse experimento é o de facilitar e contextualizar a abordagem dos conceitos de ‘transmissor’ e ‘receptor’ em um circuito envolvendo o infravermelho. Essa atividade pode ser abordada mediante a problematização de questões como a obsolescência programada associada aos equipamentos eletrônicos, a fim de levar os alunos à conscientização dos impactos ambientais e sociais decorrentes desse problema.Imprensa Universitária - UFSC2015-10-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2015v32n3p80910.5007/2175-7941.2015v32n3p809Caderno Brasileiro de Ensino de Física; v. 32 n. 3 (2015); 809-8232175-79411677-2334reponame:Caderno Brasileiro de Ensino de Física (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2015v32n3p809/30637Copyright (c) 2015 Caderno Brasileiro de Ensino de Físicainfo:eu-repo/semantics/openAccessAssis, AliceSouza, Jéssica Miranda eCarneiro Junior, Jorge LuisOliveira, Henrique Buday de2018-03-16T12:39:43Zoai:periodicos.ufsc.br:article/37147Revistahttp://www.periodicos.ufsc.br/index.php/fisicaPUBhttps://periodicos.ufsc.br/index.php/fisica/oaicbefisica@gmail.com||fscccef@fsc.ufsc.br|| cbefisica@gmail.com2175-79411677-2334opendoar:2018-03-16T12:39:43Caderno Brasileiro de Ensino de Física (Online) - Universidade Federal de Santa Catarina (UFSC)false |
