Optics and children
Costa, Manuel F. M.; Campos, J. Ayres de; Lira, Madalena; Franco, Sandra; Vazquez-Dorrio, José B.Light and Optics are subjects that “naturally” attracts the interest and sympathy of children even from very early ages. In this communication, we present a serie of experiments and support material designed in this hands-on perspective, to be used to introduce the study of light and optics to kindergarten and early basic school students. Our hands-on investigative approach leads the students, aged 4 to 10 year...
Stress and deformation in tubular metallic parts of auto seats
Costa, Manuel F. M.; Vazquez-Dorrio, José B.; Melo, Francisco Queirós de; Carneiro, Joaquim A. O.In order to assess the structural and material behaviour in particular the deformation and failure in lightweight metallic tubular structural parts of auto seats a pseudo-dynamic procedure was devised. The deformation of circular section tubes subjected to centred transversal force is assessed by rugometric and microtopographic optical inspection.
Surface charaterization of soft contact lenses by atomic force microscopy
Lira, Madalena; Costa, Manuel F. M.; Vazquez-Dorrio, José B.; Serra, Carmen; Oliveira, M. Elisabete; Franco, SandraThe aim of this study is to analyze surface properties of different hydrogel and silicone-hydrogel contact lenses (CL) using Atomic Force Microscopy (AFM) Several commercial CL prepared by the same method of manufacture (cast-moulding), with different monomers composition, water content and surface treatment were used in this study. Surface roughness analysis was performed using AFM on Tapping® Mode using st...
Recursos dispoñibles e modalidades de emprego das actividades manipulativas na ...
Vazquez-Dorrio, José B.; Blanco-García, Jesús; Costa, Manuel F. M.É ben sabido que unha forma de facilitar o aprendizaxe dos contidos relacionados coa Física consiste no emprego de metodoloxías activas. Entre as distintas opcións, o profesorado pode empregar as Actividades Manipulativas (AMs) que utilizan, debidamente contextualizados, materiais, obxectos, instrumentos ou montaxes experimentais tanto na aula como fora dela (Costa e Dorrío 2010). Neste obradoiro eminentemente ...
