The meeting took place from 4th-11th March 2016 when 14 DCG students accompanied by two teachers visited Sint-Calasanzinstituut in Nijlen, Belgium. As a part of Erasmus+ project on Natural Science for Social Impact, we visited the Museum of Natural History and Planetarium in Brusselles, Isotopolis, where managing nuclear waste was presented; Antwerpen, the city of diamonds; quaint Brugge and a Waste Collection Centre. At school, Belgian hosts prepared a range of very interesting research workshops, where we assumed the role of criminologists and forensic detectives, as we solved a mystery murder using natural science knowledge. /Ana Bavec/
