Teaching Bernoulli's Principle through Demonstrations

ABSTRACT

One proven strategy to help students make sense of abstract concepts is to sequence instruction so students have exploratory opportunities to investigate science before being introduced to new science explanations (Abraham and Renner 1986 Abraham, M. R. and Renner, J. W. 1986. The sequence of learning cycle activities in high school chemistry. Journal of Research in Science Teaching, 23: 121–143. [Crossref], [Web of Science ®] , [Google Scholar]; Renner, Abraham, and Birnie 1988 Renner, J. W., Abraham, M. R. and Birnie, H. H. 1988. The necessity of each phase of the learning cycle in teaching high school physics. Journal of Research in Science Teaching, 25: 39–58. [Crossref], [Web of Science ®] , [Google Scholar]). To help physical science teachers make sense of how to effectively sequence lessons, this article summarizes our experiences using an exploration–explanation sequence of instruction to teach Bernoulli's principle to prospective middle and secondary science teachers in a science methods course. We use demonstrations during our Bernoulli unit to help students go back and forth between their observations of phenomenon and what occurs on the microscopic level with what we have termed molecular talk. Students engage in guiding questions, consider their old and new understandings of science, and use evidence to construct new ideas during all stages of the lesson.     

The evolutionary history of two species of Orthocladiinae (Diptera: Chironomidae) from Lake Baikal (Eastern Siberia)

The evolutionary history of two species belonging to the genus Orthocladius van der Wulp, 1874 van der Wulp, F.M. (1874), ‘Dipterologische Aanteekneningen’, Tijdschrift voor Entomologie, 17, 109–148. [Google Scholar] (Diptera: Chironomidae) from Lake Baikal was investigated using the mitochondrial gene coding the first subunit of the cytochrome c oxidase (CO1 mtDNA). The phylogenetic analysis indicated that the Baikal Orthocladius species were divided into two well-defined clades where O. (Orthocladius) gregarius Linevitsh, 1970 was a sister species to Palaearctic O. (Orthocladius) nitidoscutellatus Lundstrom, 1915 and the O. (Eudactylocladius) sp. was a sister species to Nearctic O. (Eudactylocladius) subletteorum Cranston, 1998 Сranston, P.S. (1998), ‘Nearctic Orthocladius Subgenus Eudactylocladius Revised (Diptera: Chironomidae)’, Journal of the Kansas Entomological Society, 71(3), 272–295.[Web of Science ®] , [Google Scholar]. Divergence time estimates indicated that these species had been evolving independently for about 18 Ma (Neogene, Early Miocene), while emergence of the most recent common ancestors of the modern O. (Orthocladius) gregarius and O. (Eudactylocladius) sp. was dated to about 3.5 Ma (Neogene, Pliocene). The evolution of Baikal orthoclads occurred from the rheophilic fauna under conditions of global climate change during the geological history of the Baikal Depression in the Tertiary Period.

Currently, Phylloicus has 55 extant species, 19 of which are recorded from Brazil, and a fossil species from Dominican amber. In this paper, a new species of Phylloicus is described and illustrated from specimens collected in Amazonas State, Brazil. This new species has peculiar hind wing venation, with vein R₄ attached basally to the base of R₂₊₃. Therefore, a modified diagnosis to the genus is presented to include Phylloicus dumasi sp. nov. The new species is somewhat similar to P. paprockii Prather, 2003 Prather, A. L. 2003. ‘A revision of the Neotropical caddisfly genus Phylloicus (Trichoptera: Calamoceratidae)’.

Hydrotrupes chinensis Nilsson, 2003 (Coleoptera: Dytiscidae): new records, (re)description of adult and larva,and notes on its biology

Abstract

Hydrotrupes chinensis Nilsson, 2003 Nilsson, A.N. (2003), ‘Dytiscidae. XII. A New Species of Hydrotrupes Sharp from China, an Example of Pacific Intercontinental Disjunction (Coleoptera)’, in Water Beetles of China (Vol. 3), eds. M.A. Jäch and L. Ji, Vienna: Zoologische-Botanische, Gesellschaft, pp. 284–297. [Google Scholar] described from the holotype collected in Anhui Province, China, is newly recorded from three localities in Guangdong Province, ca. 750?km southwest from the type locality. The species seems to inhabit hygropetric habitats exclusively, with diurnal larvae and nocturnal adults hidden under stones or in cracks in rock during the day; when disturbed, the adults readily jumped off the rock surface. The adult is redescribed. The larvae are described and illustrated for the first time, with detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment, and urogomphi. Whereas similar morphologically to the Nearctic endemic Hydrotrupes palpalis Sharp, 1882 Sharp, D. (1882), ‘On Aquatic Carnivorous Coleoptera or Dytiscidae’, Scientific Transactions of the Royal Dublin Society, 2, 179–1003. [Google Scholar], the first instar larva of H. chinensis distinguishes by presence of six lamellae clypeales, two additional spine-like setae both on the last abdominal segment and urogomphomere 1, and the strongly developed egg bursters.     

A new species of Larsia Fittkau, 1962 (Diptera: Chironomidae: Tanypodinae) from phytotelmata of Aechmea distichantha Lemaire, 1853 (Bromeliaceae) in Argentina

The multivoltine life history of Cheumatopsyche brevilineata (Iwata, 1927) (Trichoptera: Hydropsychidae), with a new method to estimate the population size of generations

Cheumatopsyche brevilineata (Iwata, 1927 Iwata, M. (1927), ‘Trichopterous Larvae from Japan’, Zoological Magazine, 39, 209–272. (In Japanese) [Google Scholar]) is a filter-feeding caddisfly without distinct separable generations. We conducted a life history survey of C. brevilineata under a natural thermal regime. This caddis species had a multivoltine life history and their generations partially overlapped each other. From the seasonal change of larval and pupal density, we recognized one overwintering generation and three non-winter generations. We propose a new method to estimate the population size of fourth instar larvae from each generation by using the ‘development zero’ and ‘effective degree-days’ methods. The second non-winter generation, developing under the hottest water temperature regime, had the largest population size and highest observed density. The overwintering generation, which developed under the coolest thermal regime, showed the smallest population size but its observed density was not the smallest.     

Four new species of the genus Cheimacheramus Barnard, 1934 from Madagascar (Trichoptera: Sericostomatidae)

(1934), ‘South African Caddis-Flies (Trichoptera)’, Transactions of the Royal Society of South Africa, 21, 291–394.[Taylor &; Francis Online] , [Google Scholar] included only three species, one from South Africa and two from Madagascar. Four new Malagasy species are described herein: Cheimacheramus akandi sp. n., Cheimacheramus barnardi sp. n. and Cheimacheramus anjojorobensis sp. n. from the Anjojorobe Forest, Cheimacheramus madecassus sp. n. from the Lakato Forest and the Marojejy National Park. Diagnostic characters of the genus and species are discussed and illustrated. In Madagascar, these discoveries confirm the localization of the genus within the eastern evergreen forests.

Rotifers from a humic coastal lagoon of Rio de Janeiro State,Brazil

Abstract

A four-year study of species composition of the zooplankton community was conducted at Lagoa Comprida, a Brazilian coastal lagoon. Forty-two species of rotifers were recorded and illustrated. All rotifer species, except Lecane boettgeri Koste, 1986 and Macrochaetus kostei, José de Paggi, Branco &; Kozlowsky-Suzuki, 2000 José de Paggi, S, Branco, C WC and Kozlowsky-Suzuki, B. 2000. A new species of Macrochaetus (Rotifera, Trichotriidae) in a coastal lagoon of Rio de Janeiro State (Brazil). Stud Neotrop Fauna &; Environm, 35: 157–160. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar], have already been found in other areas of Brazil. Some factors, which probably favored the dominant richness and density of rotifers in the zooplankton community, are discussed.
