ALICE Y MARIANGELA EN EL CENTRO PRINCIPIA Principia is an interactive science center which is characterized by promoting scientific and technological dissemination to a wide public in a pleasant, practical and attractive way, always maintaining accuracy in contents. It is interactive because there is a manipulation of objects that forces the visitor to think, reflect and experience, encouraging him to hear and investigate for himself the scientific basis of the natural phenomena of the world around him. The museum is linked to the education world, so that its activities have a distinctly educational scope, being a good resource for teachers and students, concerning teaching or learning of science. In reality, over 80% of visits are school groups at all educational levels, although the public hosted by this museum is the most diverse: adults, disabled, associations of various kinds, etc. JOVANA Y JOHANNA EN INTERCAMBIA MÁLAGA The project is based on various objectives: • Fomention of participation and intercultural learning • Youth Information • Fomantion of voluntary service • Tandem – language exchange • The project is developed in Málaga City and the province of Málaga, so our activities are also focused on the formation and diffusion of information in rural areas.
