A proposta desse modelo didático é tornar o conteúdo de genética “Grupos Sanguíneos”, mais significativo para o aluno. Para a realização da aula cada dupla recebe um saco contendo os alelos do sistema ABO e um roteiro sobre o desenvolvimento da dinâmica, ao final os alunos respondem a uma questão problema.

O jogo resume-se em dividir a turma em grupos e distribuir as cartas igualmente para cada grupo. Um representante do grupo se dirige ao quadro branco para desenhar a estrutura de DNA ou RNA que se encontra na sua carta para o seu grupo adivinhar.

Através de um programa de formação pedagógica para pós-graduandos, o grupo de Ensino de Bioquímica da Universidade Estadual de Campinas – Unicamp e da Universidade de São Paulo – USP vem promovendo o desenvolvimento de novas disciplinas especiais de bioquímica. Uma delas foi a Bioquímica da Nutrição inteiramente planejada e aplicada por pós-graduandos para alunos de graduação. Os objetivos da disciplina, o seu conteúdo e as formas de avaliação foram completamente reestruturados de modo que pudessem ser veiculados pela Internet. A versão virtual da disciplina foi oferecida para alunos da graduação durante quatro meses. Para ser totalmente veiculada pela Internet, foi criada uma “homepage” con...

It offers food as a gift for the female but sometimes sw...

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 ...

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...

15cm Identification: it is one of the largest hummingbirds. It is easily identified by the forked tail, reminding a pair of scissors. Unmistakably Brazilian’s best known hummingbird, this magnificent animal is also one of the most belligerent ones. It fiercely defends its territory – usually consisting of a flowering patch – against other birds, especially the bananaquit ( Coereba flaveola ). It sucks sweet water from feeders even if these are place in the interior of the houses, fearlessly entering the rooms. Like other hummingbirds it feeds mostly on nectar but also on insects. The female lays 2 or 3 eggs in a small bow-shaped nest and feeds the nestlings mainly with arthropods.

12,5 cm. The general color is green, but the male has a bright blue area in the wings and lower back. The female does not have this blue area and the belly is somewhat yellow.

Habitat: Forest borders, gallery forests, parks, gardens and open areas. Diet: Feeds on fruits, seeds, buds and flowers. Reproduction: It is monogamous. The couple stays together for the rest of their lives. The nest is built inside a hole in a tree that may be an abandoned nest of hornero (Furnarius rufus) or an artificial nest box. ...

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...

44 cm. The tail is long and there is a topknot. The ventral region is white. The wings are dark brown with black and white streaks. Distribution: From the state of Amapá to Uruguay. Habitat: Open fields, cerrado and caating, also in landscapes modified by man. Diet: Feeds on arthropods and small vertebrates. Reproduction: The nest may be individual or collective. It is built about 5m from the ground. The female lays up to 7 eggs, but there may be more than 20 eggs in collective nests. In the collective nests there is great competition for food among the hatchlings and few them survive. Natural history: When perched it waves its tail, swinging the body in a way that some peop...

28cm Identification: easily told apart from other woodpeckers for the black and white pattern, being the wings and the tail black. There is a yellow region on the face. It lives in noisy groups of 3 to 8 individuals. As other woodpeckers the diet is based on insects that it catches hammering tree trunks. The nest is built by the couple in a natural tree hole or a carved one. The female lays 3 or 4 eggs. The young birds leave the nest within about 35 days.

Natural history: During most of the day it rests...

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 ...

18cm Unlike the Red-crested Cardinal ( Paroaria coronata ) the Red-cowled Cardinal does not have a crest and the absence of black patches on the head and throat distinguishes this from the other Brazilian cardinals. This bird is endemic to the Brazilian Northeastern semi-arid region called ``Caatinga´´ where it is undoubtedly one of the most beautiful songbirds. Its beaty often costs its freedom as thousands of these birds are captured in the wild to be kept as cage birds. There is large illegal traffic of these birds throughout Brazil and even to other countries. Several specimens, and even established breeding populations have been reported considerably far from its original distrib...

75 cm. Aquatic with narrow beak curved in the tip. The feet are webbed. The body is black and sometimes the throat is yellow. In the breeding season the male has some white feathers in the throat and ear region. The immature is fuliginous. Distribution: From Mexico to Southern South America Habitat: Lives in lakes, swamps and estuaries. Diet: Feeds on fish, even spiny ones. The gastric acids dissolve the spines. Reproduction: The nest is built on tall trees near lakes, sometimes mixing with heron flocks. Natural history: It is an excellent diver. When in flocks may pen fish schools, leading them to shallow water where they catch the fishes in frenzy. When it goes out of the wate...

19cm. The plumage is squamous. The general coloration is brown with some grayish parts. There is a white wingbar (when closed). When flying it shows a pattern of white in the wings and tail. Distribution: From Venezuela to Argentina. Habitat: Inhabits dry fields, cerrado, caatinga and parks in urban areas. Diet: Feeds on grains and fruits on the ground. Reproduction: It is monogamous. Builds a sparse nest in the shape of a cup, 1 or 2m from the ground, sometimes on the ground. The hatchlings (generally 2) are fed on pigeon’s milk that is rich in fat, proteins and lectines. They leave the nest after 15 days. The vocalization is very characteristic and in many places it is named a...
