O artigo relata a experiência de uma professora de História que ao trabalhar o conceito de tempo o ampliou para o tempo arqueológico e geológico. A experiência ocorreu com alunos da atual 6ª série no ano de 1999. A abordagem de ensino foi o construtivismo.

O podcast máquina do tempo pretende abordar, neste primeiro episódio, o envelhecimento a partir do debate entre um cientista, especialista no assunto, e o host do podcast, uma pessoa fora do meio científico.

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.

Na parte superior direita aparece o título do podcast:

A Biologia é desafiadora, pois há muitos conceitos e processos difíceis de compreender até mesmo para o professor. Esse material didático é um produto que foi apresentado como trabalho de conclusão do curso de Especialização em Tecnologias Aplicadas ao Ensino de Biologia da Universidade Federal de Goiás, com o objetivo de colaborar com o reconhecimento das HQs (Histórias em quadrinhos), como ferramenta pedagógica, de forma a serem inseridas cada dia mais nos livros didáticos, na sala de aula, no cotidiano de todos, onde a análise da utilização de um conteúdo específico da Biologia – O sistema ABO – remeteu a estímulos positivos, proporcionando interação entre: arte-biologia-educação, desenvo...

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 bioquímica e fisiologia humanas, ...

Visão geral do conceito de parasitismo

O software “Movimentos das Plantas” foi desenvolvido com a finalidade de apresentar imagens em sala de aula, representando formas e fenômenos biológicos. Através de textos associados a fotos, vídeos, simulações e experimentos, o software apresenta conceitos da Biologia e aproxima os alunos de fatos reais observados na natureza. Dessa forma, o uso de imagens deixa de ser puramente ilustrativo para se tornar a base da aprendizagem de novos conteúdos, a partir da interação de cada aluno com o conteúdo visual.

O software F(C): Funções Complexas comtempla a representação gráfica do Plano Complexo a partir do conceito de domínio de cores para a geração de gráficos coloridos.

Physical appearance: 11 cm. The upper parts are dark and the inferior parts yellow. There is a white bar in the supercilium. The females are smaller than the males. The immature individuals have grey belly and do not have the bar above the eye. Distribution: From Mexico to Chile. Habitat: Inhabits various environments provided there is plenty of trees and flowers. Diet: Feeds mainly on nectar. Also eats insects. Visits hummingbird feeders. Reproduction: Builds two kinds of nest. A breeding one that is compact with thick walls and a resting nest made of leaves, grass and spider webs. Lays two or three white eggs. Only the female incubates. The male helps feeding the brood with i...

35cm Similarly to other Brazilian jays, the Curl-crested jay has white lower parts and blue and black upper parts. It may be confused with the Plush-crested jay (Cyanocorax chrysops), but while the last presents the crest in the back of the head, the yellow iris and a blue patch around the eyes, the Curl-crested jay presents the crest on the forehead, the red iris and the head is entirely black. Whereas the Old World ravens are mostly black, as well as the crows, the Brazilan corvids are colorful and most of them have white lower parts. There are 6 species of jays in Brazil, all of them extremely beautiful. The Curl-crested jay is one of Brazilian’s noisiest jays. To make the noise ...

60cm Identification: there are four mostly white species of egrets in Brazil, the snowy egret can be told apart by its smaller size and also for having the tip of the beak black and for having dark legs with yellow feet. Laypeople usually think this species is a young great egret, however it is technically different enough to be place in another genus. It is bit more demanding than the great egret regarding its habitat necessities, as it does not occur in polluted waters and is more strongly associated to aquatic plants such as the water lily. Its reduced size allows this bird to walk over the aquatic plants without sinking. It feeds mainly on small fishes and tadpoles. The nest is ...

16cm Identification: the genus Elaenia is well known among the ornithologists for being one of the most difficult groups when it comes to species identification. Nevertheless Elaenia flavogaster is the easiest species to be identified, first for its yellow belly, second for the crest on the head (not always visible), third for the absence of white patches on the face and crest and last for its conspicuous behavior. It is more easily heard than seen and its song reminds the one of the kiskadee. It inhabits parks, backyards, coffee crops and secondary forest edges. The yellow bellied elaenia spends most of its time in the medium height trees and shrubs. Feeds mainly on insects and be...

10,5 cm. The beak and a mask around the eye are bright red. The body is light brown, finely streaked. There may be a red region in the belly. As in other species of cage birds there is great color variation. Distribution: Originally in Africa but currently found in many places around the world. In Brazil it may be found in most of the country except from the Amazon region (where it may be found in the suburbs of big cities). Habitat: Open landscapes, fields, crops, gardens and parks. Diet: Seeds and occasionally insects. Reproduction: The nest is built by the couple in shrubs. Its walls are thick and made of grass, feathers and cotton. The entrance is hidden. Sometimes a false n...

35cm Identification: the head is dark with a bege band on the eyebrows and another one on the neck. The throat is white, but unlike Falco rufigularis this ribbon is not extended up to the back of the neck. The chest is light brown with black dots, unlike Falco deiroleucus which presents this region orange. The belly is dark with white spots and there is a red patch near the tail. The tail is dark with three white bars. It is one of Brazilian commonest falcons since it inhabits open landscapes, included those disturbed by men. Feeds on small rodents and birds, reptiles and large insects. Like other falcons these are monogamous birds with fixed breeding grounds. The nest is built o...

19 cm. The body is brown, darker in the back and ferruginous in the tail. The ventral part is light brown. Distribution: Northeast, Mideast to South of Brazil, also in Argentina, Paraguay, Uruguay and Bolivia. Has been spreading its distribution along with deforestation. Habitat: Open landscapes, fields, cerrado, lawns and gardens. Diet: Mainly arthropods, sometimes seeds. Reproduction: The couple builds the nest with mud, manure and straw that they carry with their beaks and model with their feet. The nest is usually built on tall trees. Each year a new nest is built, sometimes over the previous ones (up to 11 nests one above the other). The nest has two divisions and the eggs...

35 cm. The legs and the toes are long and green. Has a red shield-like structure in the forehead that is larger in the male. The neck and inferior parts are blue. The back is brown and there is a white band in the wing. The immature individuals are brown. Distribution: All over the world, except from Australia and New Zealand. Habitat: Lives in lakes, ponds and swamps, provided there is plenty of aquatic vegetation. May be found even in very polluted places and brackish water. Diet: Feeds on vegetables and aquatic insects. Usually dives to catch the food. When it does not dive it waters the food before swallowing. Reproduction: The nest is built among the aquatic vegetation. Th...

40cm. Identification: its most typical characteristic is the long forked tail. The only species it can be confused with is the Fork-tailed Flycatcher ( Tyrannus savana ), which has the lower parts in white, the head in black and the long tail feathers are broader. Very little is known about this species although it is distributed throughout central and southern Brazil even in disturbed habitats. It is usually found alone or in pairs, near wetlands. This bird spends most of its time perched. Feeds mainly on flying insects that it hunts in short flights from the perch It seems to be seasonal, but the migration routes are mostly unknown.

18,5 cm. The upper parts are greenish brown, the throat is white and the belly yellow. The tip of the tail is buffy. Male and female are similar. Distribution: From Venezuela to Argentina. Mideastern Brazil. Migrates seasonaly in southern Brazil. Habitat: Open fields, grasslands, grazing lands and parks in urban areas. Diet: Catches insects on the ground and sometimes in trees. Follows cattle to feed on insects displaced by its movement. Reproduction: Builds a nest made of branches about 4m from the ground. May use nests abandoned by the hornero (Furnarius rufus). The white eggs are incubated by the couple. Natural history: When on the ground runs for some meters then stops t...

23 cm. Very similar to the great kiskadee (Pitangus sulphuratus), but with a larger and broader beak. Distribution: From Mexico to Argentina. Habitat: In the canopy of woods, secondary forests and open areas with tall trees. Diet: Arthropods and other small invertebrates. Sometimes fruits and small fishes. Reproduction: Builds a small nest on uncovered branches of tall trees. Lays two or three eggs. Natural history: Although it is very similar to the great kiskadee it is more dependent on trees. The vocalization is very different from the one of the kiskadee. It migrates seasonally.
