"CosmoLAB" is an educational project with the goal of bringing Astronomy and, in particular, the practice of astronomical observation, closer to the educational community of the island so that teachers and students consider the Teide Observatory, the skies of the Canary Islands and the cutting-edge science done in the region as part of their cultural heritage. The project lent different types of telescopes to schools so that they can organize their own observations continuously and autonomously. Before the loan, the teachers complete a course where they learn to mount and use the telescopes. Thematic courses on Astrophysics are also offered, taught by IAC experts, with the aim of allowing direct contact between researchers and teachers and provide access to the latest scientific results. In addition, educational resources based on Inquiry Based learning are presented to the teachers so they can later address these issues in the classroom in a motivating and practical way. Here we present the results and lessons learned during the first two years of the project and we will analyse how these types of initiatives contribute to the improvement of scientific education in the region and how Astronomy can serve as a didactic resource also for other school disciplines.
