Construção de tela interativa, utilizando controle de Nintendo Wii, e sua utilização por alunos do Ensino Médio

Neste trabalho foram elaborados um tutorial para a construção e a utilização de uma tela interativa de baixo custo e um caderno pedagógico para o ensino de programação e robótica no Ensino Médio, utilizando esta tela. A construção e calibração da tela foi realizada por alunos do Colégio SESI de Jaguariaíva – PR. Posteriormente, a tela interativa e o caderno foram utilizados com alunos do mesmo Colégio. De acordo com os alunos, as vantagens indicadas são: a tela interativa facilita a execução de tarefas em grupo, permite a melhor compreensão do problema que está sendo discutido e facilita a descoberta de soluções alternativas

METODOLOGIA NO ENSINO DE FÍSICA: QUAIS CONCEITOS PODEMOS ABORDAR AO CONSTRUIR UM FANTASMA DE PEPPER?

Neste trabalho, temos como objetivo ensinar conteúdos de Física como leis da reflexão e resistividade, através do estudo de um “Fantasma de Pepper”, utilizando-se aulas experimentais com contextualizações históricas e culturais. Nessas aulas utilizamos a Teoria de Aprendizagem Significativa de Ausubel. As atividades das aulas estão contidas em dois cadernos didáticos: o do professor e o do aluno. Esses cadernos foram aplicados em uma turma de segundo ano do Ensino Médio no Colégio Agrícola Augusto Ribas, Ponta Grossa – PR, Brasil, em 2019. Para avaliar a aprendizagem dos alunos, foram aplicados questionários e produzidos mapas mentais. A análise qualitativa deste material foi realizada pelo software IRAMUTEQ e nos permite concluir que quase 2/3 dos alunos apresentaram indícios de aprendizagem significativa

Física: da universidade à comunidade

Physics - from the University to the Community The project “Physics - from the University to the Community”, since its first edition, in 1999, aims, mainly, to establish a direct bonding between the community and the Physics Department, at the State University of Ponta Grossa (Physics Department- SUPG). The activities offered by this project are: courses of leveling and courses of academic background complementing subjects, to improve the academic studies of the students of the courses of Physics and correlated areas; courses, workshops and lectures for teachers of basic schools; monitories, scientific initiation and participation in the project “Citizen of the Future”, for pupils of elementary school; assembly of laboratories and spreading of the courses of Physics, of the University, in basic public schools; accomplishment of experiments of Physics, in public places, in several cities of Paraná state.O projeto de extensão “Física - da Universidade à Comunidade”, desde sua primeira execução, em 1999, tem como objetivo, estabelecer uma ligação direta entre a comunidade e o Departamento de Física, da UEPG. As atividades oferecidas por este projeto são: cursos de nivelamento e cursos sobre temas para complementar a formação dos acadêmicos dos cursos de Física e de áreas afins; cursos, oficinas e palestras para professores dos Ensinos Fundamental e Médio (EFM); monitorias, iniciação científica e participação no projeto “Cidadão do Futuro”, para alunos do EFM; montagem de laboratórios e divulgação dos cursos de Física, da UEPG, nas escolas da rede básica de ensino; realização de experimentos de Física em lugares públicos, em várias cidades do Estado do Paraná

Giants of the Amazon:How does environmental variation drive the diversity patterns of large trees?

For more than three decades, major efforts in sampling and analyzing tree diversity in South America have focused almost exclusively on trees with stems of at least 10 and 2.5 cm diameter, showing highest species diversity in the wetter western and northern Amazon forests. By contrast, little attention has been paid to patterns and drivers of diversity in the largest canopy and emergent trees, which is surprising given these have dominant ecological functions. Here, we use a machine learning approach to quantify the importance of environmental factors and apply it to generate spatial predictions of the species diversity of all trees (dbh ≥ 10 cm) and for very large trees (dbh ≥ 70 cm) using data from 243 forest plots (108,450 trees and 2832 species) distributed across different forest types and biogeographic regions of the Brazilian Amazon. The diversity of large trees and of all trees was significantly associated with three environmental factors, but in contrasting ways across regions and forest types. Environmental variables associated with disturbances, for example, the lightning flash rate and wind speed, as well as the fraction of photosynthetically active radiation, tend to govern the diversity of large trees. Upland rainforests in the Guiana Shield and Roraima regions had a high diversity of large trees. By contrast, variables associated with resources tend to govern tree diversity in general. Places such as the province of Imeri and the northern portion of the province of Madeira stand out for their high diversity of species in general. Climatic and topographic stability and functional adaptation mechanisms promote ideal conditions for species diversity. Finally, we mapped general patterns of tree species diversity in the Brazilian Amazon, which differ substantially depending on size class

AMAZONIA CAMTRAP: A data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forest

The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer-reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non-invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from different Amazon regions to compile the most extensive data set of inventories of mammal, bird, and reptile species ever assembled for the area. The complete data set comprises 154,123 records of 317 species (185 birds, 119 mammals, and 13 reptiles) gathered from surveys from the Amazonian portion of eight countries (Brazil, Bolivia, Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela). The most frequently recorded species per taxa were: mammals: Cuniculus paca (11,907 records); birds: Pauxi tuberosa (3713 records); and reptiles: Tupinambis teguixin (716 records). The information detailed in this data paper opens up opportunities for new ecological studies at different spatial and temporal scales, allowing for a more accurate evaluation of the effects of habitat loss, fragmentation, climate change, and other human-mediated defaunation processes in one of the most important and threatened tropical environments in the world. The data set is not copyright restricted; please cite this data paper when using its data in publications and we also request that researchers and educators inform us of how they are using these data

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
