This work exposes an experimental proposal for university students using Base Learning on Problems. Such students were challenged to prepare a ceramic nanomaterial for soil decontamination; activities framed by the chemistry on solids and ceramic materials areas. The students showed their ability to propose a design of magnetic iron nanoparticles inserted in a clay montmorillonitic for the problem solution; through their abilities of investigation trustworthy literature; they stated their objectives, hypothesis and methodology for the synthesis of magnetic nanoparticles in situ, a conditioned montmorillonite; developed and interpreted the experiments; performed the structural characterization of their nanomaterials by the X-ray powder diffraction and infrared absorption spectroscopy techniques; finally, they concluded their outcome. In parallel, they developed their reflection skills, decision-making, information opinion exchange and communication; they argued, memorized and formulated their ideas. The students exposed their advances in the weekly seminars; wrote the final report in a research article format and performed an experimental sample at the Chemistry Fair at the Chemistry Faculty, UNAM.

Keywords : Chemistry teaching; Problem Based Learning; nanomaterial; magnetic nanoparticles; montmorillonite.
