Nanoscience and nanotechnology development has led to the emergence of specialized courses on this subject at higher educational level. Some universities in Mexico already have courses at the undergraduate level, and in order to attract students to this area, it seems required to motivate them starting from middle school through experimental demonstrations of matter properties at the nanoscale.

This paper presents a simple method for synthesis of silver nanoparticles designed with reagents usually available in any mid-school laboratory. The results of this experiment demonstrate that silver at this scale has different coloration to the commonly known macroscopic scale. Such change is an effect of surface plasmon resonance in metal nanoparticles.
