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.
