Thermal stability and decomposition kinetics of NdNiO3− δ at 1 bar of O2
Bassou, A. A.; Machado, P. J.; Gomes, M. M.; Manjunath, B.; Vilarinho, R.; Silva, Bruna Andreia Nogueira Airosa; Oliveira, José A.; Almeida, B. G.Despite the interest in rare-earth nickelates for applications, their processing under 1 bar of oxygen pressure is still challenging. In this work, we report the co-precipitation synthesis, thermal stability and thermally driven decomposition of NdNiO3 phase, in order to determine the synthesis parameters towards a pure perovskite phase. We concluded that using a 1% molar excess of Nd during preparation and pos...
An IBSE approach for teaching the concept of density in preschool and primary s...
Costa, Manuel F. M.; Machado, P. J.This paper intends to suggest strategies for planning, development and implementation of simple activities, related to “density”, in the classroom, in an Inquiry Based Science Education (IBSE) perspective, i.e. science education based on research/inquiry/experimentation. In this sense, we begin by contextualizing the curricular context on science teaching in preschool and primary school, and presenting the theo...

Marques, Marta Isabel Bessa; Machado, P. J.; Malheiro, Teresa; Varela, Paulo Idalino Balça; Silva, Mario Zamith; Almeida, A. M.; Costa, Manuel F. M.The main aim of this National Report is to provide concrete recommendations to policy makers and stakeholders in Portugal for further practice grounded on the research outcomes of the Creative Little Scientists project about enabling children’s creativity through science and mathematics in preschool and first years of primary education.
Experiências elementares de física para alunos do ensino pré-escolar e 1º ciclo
Machado, P. J.A inclusão das Ciências no currículo dos primeiros anos começou a consolidar-se na década de oitenta em vários países, em particular no Reino Unido, onde a investigação sobre esta temática tem sido mais notória. Em Portugal, de acordo com Martins (2006), é conhecida de todos, professores e responsáveis pela gestão curricular, a menoridade da área das Ciências no currículo do 1.º ciclo do ensino básico, quer em ...
