¿Cómo estimar la concentración de azúcar en gaseosas? Una introducción a la refractometría

In order to encourage daily practices that facilitate the construction of new ways of teaching and learning science is presented in a didactic framework enrolled at school science education, whose starting point is a triggering question: once developed the concepts associated with reflection-refraction of light in the classroom. How could estimate the concentration of sweet soda? It approaches concepts of geometrical optics in the physical classroom: reflection and refraction of light, integrating contents of chemical as chemical solutions and concentration calculation.
