Os alunos do 5º Ano, sob orientação e supervisão da professora, construíram uma bússola.Para realizar essa construção, os estudantes utilizaram os materiais: água, E.V.A., imã, agulha e um recipiente de vidro, para colocar a água.Primeiramente, os estudantes, pressionaram a agulha no imã, isto é, imantaram a agulha e a anexaram à um pedaço de E.V.A. Após essa etapa, os alunos colocaram o E.V.A., com a agulha, dentro do recipiente de vidro.Enfim, a construção da bússola foi finalizada, então, os alunos a testaram, observando a locomoção da agulha para as direções ‘Norte e Sul’.
