The EU-HOU project ("Hands-On Universe, Europe. Bringing frontline interactive astronomy to the classroom") is in keeping with the general goal of renewing the teaching of science. A re-awakening of interest for science in the young generation is foreseen through astronomy and the use of new technologies, which should challenge middle and high schools pupils. Bringing interactive frontline astronomy to the classroom» aims at engaging young minds in science through creative thinking and planning of activities in astronomy. It is a collaboration of 8 European partner countries promoting science as an exciting learning activity for all abilities. Tools and software for astronomical observations and image handling, together with stimulating interactive cross-curricular multi-media exercises and resources are freely available on the web in English and the national languages. Emphasis is given: a) on real observations, possibly acquired by the pupils themselves in classrooms thanks to either a European and worldwide network of automatic telescopes operated via Internet or didactical tools (Webcam system, radio telescope) developed within this project. These observations can be manipulated in classrooms with a specific software designed to be pupils friendly. They are integrated into pedagogical resources constructed in a close collaborative work between researchers and teachers. b) on class-ready resources and projects, easy to be used, that has been developed by the partners, inspired from research activities. The EU-HOU project is funded at 44% through the European program MINERVA (SOCRATES) for a two-year period. More information on the project, the partner Institutions, the Pilot Schools that are collaborating with the project across Europe and the results of the experience can be found in the network URL: www.euhou.net. In this talk we will describe the results of the first two years of hard and very successful collaboration. Special emphasis will be given on material developed in Greece and the Greek network.
