Este artigo analisa a organização do componente curricular de Ciências nos anos iniciais doEnsino Fundamental da rede pública de Maringá/PR. Por meio de uma pesquisa documental deabordagem qualitativa, o estudo examina as prescrições dos conteúdos, competências e objetosde conhecimento em três documentos oficiais: a Base Nacional Comum Curricular (BNCC), oReferencial Curricular do Paraná e o Currículo da Educação Municipal de Maringá. A análisecomparativa revela uma forte coerência estrutural e temática entre os documentos, queestabelecem uma progressão hierárquica do geral para o específico. A BNCC define ascompetências nacionais, o Referencial do Paraná as detalha para o contexto estadual, e ocurrículo de Maringá as organiza para a aplicação local, distinguindo-se por um aprofundadoreferencial teórico-metodológico. Conclui-se que há um alinhamento claro na prescrição dosconteúdos, garantindo uma base curricular consistente, embora a complexidade teórica dodocumento municipal aponte para desafios significativos na sua transposição para a práticapedagógica.

This article highlights the reality of María Zambrano’s American exile, which was first experienced as an inevitable moment of personal deconstruction and later perceived as a place of unique revelations. The Spanish philosopher experiences the space and time of exile as a “miracle of an identity in perpetual balance”, allowing her to rethink history and regenerate the ongoing creative opportunity to offer the world a hope for unity, where true salvation lies not in “escape” but in the precious chance for spiritual edification. It is a hope to be desired forever, especially today.
