1. Isqueiro Pneumático: uma ferramenta versátil ao ensino interdisciplinar
Resumo O isqueiro pneumático é um equipamento que permite produzir fogo por meio de rápida compressão do ar e, quando construído com tubo de acrílico transparente, é possível observar a queima de uma pequena amostra de algodão colocada em seu interior. Por ser um instrumento pouco conhecido e cujo funcionamento chama a atenção vislumbramos seu uso

2. Una revisión de literatura sobre el uso de sistemas de adquisición de datos para la enseñanza de la física en la educación básica, media y en la formación de profesores
This paper presents a literature review that approaches the current state of the data acquisition systems implementation in physics teaching; mainly at Middle and High School levels and in teachers training. The main search was performed in 35 journals found in the following databases: Science Direct, Scopus, Web of Science and Google Scholar, taking into ac

3. "Serpentes de Faraó": a história de uma brincadeira pirotécnica e sua aplicabilidade no ensino de princípios químicos básicos
Fun methodologies developed with alternative materials for teaching chemical reactions of carbon are interesting activities for discussing concepts of stoichiometry and thermochemistry. The decomposition of organic matter, CO2 production and coal formation can be demonstrated in the experiment "Pharaoh´s snake". This experiment is attractive since the simpl

4. Un método para enseñar el porqué suceden las reacciones químicas
A methodology is proposed for explaining one of the central questions in the teaching of general chemistry courses to freshman students: why do chemical transformations occur? The answer to this question is based on thermodynamics but we propose arriving at an answer in a more intuitive way by using computational tools in a bid to increase the motivation of

5. Dinâmica natural e ensino de Química para jovens e adultos : saberes e práticas de uma inovação curricular / Natural dynamics and teaching chemistry to adult education : knowledge and practices of curriculum innovation
The curricular innovation was applied and evaluated to understand terrestrial environments in order to teach chemical concepts. Contents were organized to understand a social and environmental problem. The issue was chosen to attract adult students. The houses of people in the city of Cajamar (in the Brazilian state of São Paulo) were destroyed or damaged b

6. Aproximación didáctica a la termodinámica con modelos y literatura de ciencia ficción
Energy transformations teaching at secondary school, generally relate to conservation and transference. Moreover, the subject related to the dispersal of energy receives no special attention. There is a general consensus that entropy is one of the more difficult concepts. So we made an investigation with students from the last year of the secondary school wh

7. Cálculo do volume na equação de van der Waals pelo método de cardano
Analytical solutions of a cubic equation with real coefficients are established using the Cardano method. The method is first applied to simple third order equation. Calculation of volume in the van der Waals equation of state is afterwards established. These results are exemplified to calculate the volumes below and above critical temperatures. Analytical a

9. Diagramas de Ellingham e de Van't Hoff: algumas considerações
The main subject of this article is to show the parallelism betwen the Ellingham and Van't Hoff diagrams. The first one is a graphic representation of the changes in the standard Gibbs free energy (deltarGtheta) as a function of T and was introduced by Ellingham in 1944, in order to study metallurgic processes involving oxides and sulphides. On the other han
