Tensión superficial: un modelo experimental con materiales sencillos
Info
Abstract
En este trabajo se presenta una propuesta didáctica basada en una actividad experimental utilizando materiales de muy bajo costo, orientada a lograr que los alumnos comprendan e interpreten el fenómeno de tensión superficial conjuntamente con la importancia de la modelización en ciencias. Tiene como objetivo principal de enseñanza acercar al alumno a la mecánica de los fluidos estáticos y las fuerzas intermoleculares, combinando contenidos científicos con cuestiones cercanas al estudiante lo que proporciona una motivación adicional a la reflexión de la investigación científica.
Palabras clave: tensión superficial; interacciones moleculares; modelos, experiencias sencillas de físicas.
Superficial tension: experimental model with simple materials
In this work appears a didactic offer based on an experimental activity using materials of very low cost, orientated to achieving that the student understand and interpret the phenomenon of superficial tension together with the importance of the modeling in sciences. It has as principal aim of education bring the student over to the mechanics of the static fluids and the intermolecular forces, combining scientific contents with questions near to the student what provides an additional motivation to the reflection of the scientific investigation.
Keywords: superficial tension; molecular interactions; models, simple experiences of physical.
