In order to explain some optical phenomena as the reflexion, the refraction, diffraction, the scattering, the absorption and the emission of the light we made an OPTICAL WORKSHOP. In these workshops, we visited schools of different academic levels and we did easy and fun experiments to prove to children and to young people that the science is closer to them. We tried to show them that the science is important in our daily life and that everybody can study science. We usually participate in workshops organized by the University Jaume I. In this year, we participated in the following University’s workshops: 1) “Practica a l’UJI”, 2) “FIRUJICIENCIA 2017”, 3) “Colònies Cientìfiques a L’UJI 2017” and 4) “Connect amb la Ciència de la Universitat Jaume I”. It should be noted that our activities were successful, considering that were attended more than 500 pupils. On the other hand, we can say that in the most cases, the optical workshops have become the first contact of society with the science and with our university. Finally, we believe that these workshops help us to promote our outreach activities and the University Jaume I. Moreover, we have shown to the children and teenagers that to study science can be a good option.
