CIENCIA EN LA CALLE.

"Ciencia en Acción" (the Spanish version of Science on Stage) is organised every year by CSIC, FECYT, RSEF, RSME and UNED. Every year the quality and number of projects presented increase and 2007 was the first year in which projects were accepted from all Spanish and Portuguese speaking countries. More than 100 projects from primary and secondary schools and universities were presented to more than 15000 visitors over two days. Participants from of all the Spanish regions, Portugal, Argentina, Colombia, El Salvador and Uruguay showed their proposals distributed into 14 categories (Physics Demonstrations, Chemistry Demonstrations, Mathematics Lab, Biology and Geology Lab, Science and Technology Projects, Didactic Materials on paper and on digital support, Outreach Works on paper and on other supports, Sustainability, Values of Science and Engineering, Performances and Science Films). During the festival we enjoyed the final event of the Spanish contest "Adopta una Estrella" related to the international "Catch a Star". The project involved groups of secondary and primary school students and teachers each preparing a report about an astronomical object. [ABSTRACT FROM AUTHOR]
