- Lecturing of the topics of the theoretical syllabus.
- Supervised accomplishment of practical assignments previously prepared in groups that are formed in accordance with a rotation system. Possible use of a laboratory logbook to register data. The last hour of the classes is intended to analyse and discuss the obtained results.
- Elaboration of reports that should include a presentation of the results using graphics and tables and their analysis and discussion.
