Una reacción química de cine.

The study of natural sciences in the second year of Secondary Education must be complemented with a visit to the laboratory, where experiments should be performed. The curriculum emphasizes the initial basis of Chemistry and the study of reactions. In this paper we describe a laboratory experience, useful for understanding the concept of chemical change. Also, we present the hypothesis that a chemical reaction was used in the classic movie The Ten Commandments. [ABSTRACT FROM AUTHOR]
