AbstractEste trabalho tem como objetivo a caracterização e comparação dos consumos alimentares domésticos de duas comunidades caboclas localizadas numa região de várzea sazonal (Ilha do Ituqui, Santarém-PA) no Baixo Amazonas (1995-97). Especial ênfase é dada ao papel da agricultura no consumo alimentar destas populações. Os resultados obtidos indicam níveis elevados de consumo protéico em relação ao calórico, pela população local, relativa instabilidade sazonal das fontes de energia e crescente dependência de itens alimentares industrializados. Apesar deste perfil, produtos localmente produzidos e obtidos, como a farinha de mandioca e o peixe, ainda representam grande parte da estrutura dietética destas populações. Somado a isto, um amplo leque de atividades de subsistência e de mercado, bem como a exploração de diferentes zonas ecológicas na obtenção de alimento, foram observados, desmistificando algumas das pressuposições dominantes até recentemente sobre a homogeneidade e simplicidade das estratégias produtivas destas populações.<br>The main objective of this research is to characterize and compare household food intake of two riverine populations located in the Floodplains of the Lower Amazon (Ituqui Island, Santarém-PA) (1995-97). A special emphasis is given to the role of agriculture in the food consumption patterns of these populations. The obtained results indicate high levels of protein intake in relation to energy intake, relative seasonal instability of energy sources, and increasing dependency on imported industrialized foodstuffs. In spite of such a pattern, food items locally produced such as manioc flour (farinha) and fish remain as the main part of local diet. In addition, a broad array of subsistence and commercial activities as well as the intense exploitation of different ecological zones by the local population were observed. The above scenario tends to undermine some of the major assumptions on the supposed environmental homogeneity and simplicity of productive strategies among native populations, which have dominated until recently the development of academic knowledge and practice.

PALS - Performance Assessment Links in Science1999-01PALS is an on-line, standards-based, continually updated resource bank of science performance assessment tasks indexed via the National Science Education Standards (NSES) and various other standards frameworks. The tasks, collected from numerous sources, include student directions and response forms, administration procedures, scoring rubrics, examples of student work, and technical quality data calculated from field testing. On-line rater training packets have also been created for some tasks. PALS is supported by a grant from the Elementary, Secondary, and Informal Education (ESIE) Division (Grant #: ESI-9730651) of the National Science Foundation.

NASA Earth Observatory: Biomes (title provided or enhanced by cataloger)This National Aeronautics and Space Administration (NASA) website allows students to investigate biomes and then test their knowledge by completing missions. The site provides basic data about each biome such as temperature, precipitation, vegetation, location, description and links. Biomes discussed include coniferous forest, temperate deciduous forest, desert, grassland, rainforest, shrubland and tundra. The two missions (available at beginner and advanced levels) are designed to teach students about the relationship between temperature and precipitation and plants in biomes. A teacher resource guide provides details about goals, expected outcomes, extension ideas, and hands-on activities.
