Laboratório de Tecnologia Educacional BIBLIOTECA DIGITAL               DE CIÊNCIAS

A atividade busca oferecer a oportunidade para os alunos vivenciarem a experiência de acompanhar o desenvolvimento de uma planta. Com a intenção de investigar o processo de Fotossíntese e o crescimento das plantas, essa prática tem o objetivo de aprofundar o olhar sobre os principais fatores favorecedores da germinação, assim como os fatores limitantes da fotossíntese.

Atividade didática com abordagem investigativa, que utiliza como estratégia a rotação de estações, com tempo cronometrado e materiais diversos para consulta, como: material biológico, textos didáticos e jornalísticos, charges, gráficos, tabelas e infográficos para dar suporte a resolução de situações problemas sobre conceitos de saúde pública, para os estudantes do primeiro ano do Ensino Médio.

O meio rural não é mais um espaço onde são desenvolvidas atividades exclusivamente agrícolas, já que, tem passado por intensas mudanças, que induzem a pluriatividade, fazendo com que o espaço seja tido como um continuum da zona urbana. Estas mudanças que assemelham o rural do urbano trazem, a reboque desta reestruturação, mazelas há muito discutidas e pouco solucionadas, das “cidades�, como uso e ocupação do solo de maneira desregrada, ausência de saneamento básico, entre outras. A respeito do saneamento, o Gerenciamento Integrado de Resíduo Sólido ainda é uma realidade bem distante, para as comunidades rurais, mesmo para aquelas juntas às zonas urbanas. Desta forma, ...

Roteiro de aula prática cujos objetivos são: 1) Demonstrar parcialmente a técnica de isolamento de mitocôndrias. 2) Caracterizar a presença da desidrogenase succínica na fração mitocondrial. 3) Demonstrar a inibição enzimática competitiva.

Experimento didático com abordagem investigativa, que traz como estratégia a execução de experimentos sobre difusão simples e osmose antes da aula teórica, estimulando assim o levantamento de questões e hipóteses sobre os processos observados na prática, além de promover uma discussão sobre a importância da ciência e como ela está presente no dia a dia do aluno.

Sequência didática com abordagem investigativa, que utiliza como estratégia a produção de vídeos explicativos e construção de jogos educativos, que colocam os estudantes no papel de educadores, trazendo as informações pesquisadas fora do período de aula de forma diferenciada aos colegas de classe.

O objetivo específico do software é oferecer os conceitos fundamentais sobre o tema de modo simplificado, tornando-os acessíveis à maioria dos estudantes do ensino médio, possibilitando a aquisição de novos conhecimentos, a solução de dúvidas e, principalmente, o surgimento de novas questões sobre um tema que ainda tem muitos aspectos a serem explorados. O software tem a vantagem do recurso visual e do caráter dinâmico que facilitam o entendimento das reações que não são de fácil compreensão para todos os alunos. A informação é apresentada de diferentes maneiras: textos, esquemas, figuras e animações. O software apresenta conceitos básicos sobre a bioquími...

Unmistakably identifiable for being the only Brazilian member of the family to present the white color in its plumage. Belonging to the same family of the legendary Egyptian Ibis, this is certainly an amazing species. Unlike other members of the family it is not associated to water, living in open grasslands and crops where its large silhouette makes it impossible not to be noticed, especially when they gather in groups. It uses its large curved beak to catch invertebrates burried in the soil and may also prey on small vertebrates. Its song is very loud and acute, reminding that of the Seriema ( Cariama cristata ). Couples sing in duets bouncing their heads upwards as they sing. The ...

There are three other very similar species from the same genus in Brazil. The females and imature individuals are nearly impossible to tell apart, as they are light brown with some darker streaks. The Saffron Finch can be distinguished from the other species for the saffron color, mostly in the breeding season. The Orange-fronted Yellow Finch ( S. columbiana) is smaller than the Saffron Finch, the Stripe-tailed Yellow Finch (S. citrina) has greenish patches on the upper parts and the Grassland Yellow Finch (S. luteola) has brownish spots even in the head. One of the countryside’s most famous birds, the Saffron Finch’s song is unique for its beaty and complexity. Unfortunately its song...
