Resumen:
Every day, nanotechnology has a stronger presence in our daily life,
with a wide variety of applications. Therefore, it is essential to
include it in the educational curriculum at all educational levels. In
Mexico, science teaching is very limited, particularly in the
experimental part, which influences their understanding. A program was
developed to teach nanotechnology to junior high school students, which
began with theoretical and practical activities on topics of
nanoscience, nanotechnology and bio-nanotechnology. To complete the
program, students developed a project to apply nanotechnology to a
problem that affected their community. The proposed project involved the
use of silver nanoparticles (AgNPs) to reduce microbial contamination in
wastewater, in order to improve the quality of life. Samples treated
with AgNPs showed a reduction of the microbial load. At project
completion, students understood concepts of nanotechnology. The project
allowed them to propose solutions to important problems in their
community. Students learn better and show greater interest when teaching
in the areas of nanoscience and nanotechnology includes experiments and
other dynamical activities. These activities will leave a very favorable
perception and awareness about science in the students involved.
