This is the second year our group participates in the Science Week organized by the Catalan Local Goverment (Nov 14-23). The event consists in talking about our experience as researchers to a large group of students in a Secondary School. Last year Mar visited a school in Badia del Vallès, one of the most densely populated neighborhoods in the periphery of Barcelona (“Badia City”) and this year Jose Luis has been to a school in Granollers (in the picture), a city located 25 Km away from Barcelona.
