In recent years there have been big advances in women taking up scientific and technological studies and joining the workforce in those areas. However, in fields such as Physics, Engineering and Informatics women are still under-represented, already at the undergraduate level. In order to help achieve full and equal participation in science by women, to recognize their achievements and to promote career perspectives in science among girls and young women many initiatives have been put in place around the world. "Habla con ellas - Mujeres en Astronomia", lead by the IAC in Tenerife, is aimed for Spanish educational Centres of all types and levels, with the goal to promote the role of women in science and to encourage scientific and technological vocations among girls as well as boys. In this lunch talk I will present the initiative and discuss my personal experience as a member of the group of female astronomers participating in it, focusing on the aspect of gender stereotypes.
