espanolEn este trabajo se presenta un proyecto de inmersion en el mundo de la ciencia a escala nanometrica. Este proyecto se desarrollo con alumnos de 4o de ESO, a los que se les presento un fenomeno sobre el que tenian que indagar. Dicho fenomeno consistio en la aplicacion de un aerosol sobre muestras textiles observando como este aerosol evitaba que los textiles se ensuciaran. El objetivo principal de la experiencia ha sido analizar las destrezas que los alumnos han desarrollado en el proceso para dar explicacion al fenomeno observado. Se ha prestado especial atencion al tipo de preguntas que estos formularon a lo largo de la actividad. A partir de las preguntas, se han analizado las destrezas y su nivel de desempeno en esta experiencia de indagacion en grupo colaborativo. Se puede concluir que los niveles de desempeno relacionados con la planificacion y la observacion son bajos. Por otro lado, parte del alumnado ha conseguido dar explicacion al fenomeno planteando las preguntas adecuadas. EnglishThis paper presents a project of immersion in the world of science to scale Nano. This project was developed with the students of 4o CSE. These were presented with an unknown phenomenon on which to enquire. This phenomenon consisted in the application of an aerosol on textile samples observing how this spray prevented the textiles from getting dirty. The main goal has been to analyse the skills developed by the students in the process of explanation to the observed phenomenon. Special attention to the kinds of questions they made throughout the process has been paid. From these questions, the skills and their level of performance has been studied in this experience of research in cooperative group. It can be concluded that the performance levels related to planning and observation are low. On the other hand, some students were able to give explanation to the phenomenon by posing the right questions.
