CRYSTALLIZATION CONTEST AT SCHOOL

摘要

Early in the morning of Saturday, May 10, in the central building of the Spanish Research Council (CSIC) in Madrid, forty teams of school students and their teachers were mounting their stands to display the crystals they had grown. It was the finale of the Crystallization Contest at School, an initiative to celebrate the International Year of Crystallography. Prior to this final contest, 7013 students, 286 teachers, and 189 schools competed in seven regional contests. The students worked in their school laboratories or in their home kitchen trying to obtain good crystals in one or several of the four modalities of the contest: crystallization of ammonium di-hydrogen, geode formation, crystallization of sodium chloride, and crystallization in gels.
