"Theater is pure Chemistry; Chemistry is pure Theater" is a project developed in the University of Valencia in which a group of undergraduate students have to write a theatre play, which must be performed by themselves on a stage. It is essentially an academic activity that seeks two goals: first, that the authors/actors face the challenge of motivating a group of youngsters (16-18 years old) to study Chemistry. And second, they have to analyze the most basic chemical concepts in depth, in order to find that metaphor or unexpected situation that allows them to approach Chemistry in a different but amusing way. During the last four years, more than one hundred Chemistry, Biology, Pharmacy and Mathematics students have enjoyed the possibility of discovering their role as actors/actresses and awaken their own potential as future teachers. The project has been awarded with the 2010 Educational Innovation Award of the "Premios del Consell Social-Universitat de Valencia".
