Fernando López-Gallego, Ikerbasque fellow at CIC biomaGUNE has visited the Public School Santo Domingo de Silos en Villaminaya, Toledo (Spain) in order to bring chemistry closer to the students. Students between 3 and 6 years have played with some scientific guessing games and enjoyed with some simple experiments, while students from 6 to 12 years have seen some illustrative videos on biology and biochemistry and made a reaction experiment.
