<span>In this work the objective was to evaluate four treatments using dung of different kinds from experimental cultures, estimating their efficiency in relation to pisciculture production and the characteristics of each pond. The work was carried out in the Laboratorio de Hidrobiología of the Universidad Autónoma del Estado de Morelos (UAEM) in Cuernavaca, Morelos, Mexico, in fiberglass ponds with albinotic </span><em>Oreochromis niloticus</em><span>. Analysis was made of plankton, as well as bacteriological, dietectic and piscicultural growth and the physical chemistry of water. Fresh chicken excrement showed variations in the amount of nutriments. Abundance of phytoplankton was from 17,008 to 70,080 org/ml. The most abundant was </span><em>Closterium sp</em><span>. In zooplankton, total abundance was from 302 to 1,706 org/ml. The dominant zooplankton was </span><em>Moina sp</em><span>. with a yield from 22 to 117 g/m</span><sup>2</sup><span>/ 6 months. Considering these findings, it was observed that the digested chicken dung was the most efficient of the four. Pathogenic enterobacteria were always present.</span><br><span style="font-family: Times New Roman; font-size: small;"> </span><p><span style="font-family: "Trebuchet MS","sans-serif"; font-size: 10pt;">En este trabajo, el objetivo fue evaluar cuatro tratamientos utilizando estiércoles de diferentes tipos en cultivos experimentales, estimando su eficiencia en relación a la producción piscícola y las características de cada estanque. Se llevó a cabo en el Laboratorio de Hidrobiología de la UAEM en Cuernavaca, Morelos, México; en estanques de fibra de vidrio, con <em>Oreochromis niloticus</em> albina. Se realizaron análisis del plancton, bacteriológicos, bromatológicos, crecimiento piscícola y fisicoquímicos del agua. Las excretas frescas de pollo presentaron variaciones en la cantidad de nutrimentos. Las abundancias de fitoplancton fueron de 17,008 a 70,080 org/ml. Los más abundantes fueron <em>Closterium sp</em>. En el zooplancton, las abundancias totales fueron de 302 a 1,706 org/ml. El dominante fue <em>Moina sp</em>. El rendimiento fue de 22 a 117 g/m<sup>2</sup>/6 meses. Considerando lo anterior se observó que la gallinaza digerida fue el estiércol más eficiente de los cuatro. Siempre estuvieron presentes enterobacterias patógenas.</span></p><span style="font-family: Times New Roman; font-size: small;"> </span>Date

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.
