Learning outcomes of the course unit

Knowledge: The course provides the student with an opportunity to
address several practical experiences using the approach of the
researcher and therefore no longer that, although very useful, of the
replication of an experimental result.
The course highlights the importance of the observation of the
phenomenon with respect to the replication of the phenomenon.
One of the aims of the course is to teach the students how to establish
the methodology and procedure for running an experiment.
The chemical basis of important phenomena of inorganic chemistry are
explained, focusing onhow to exploit the properties of substances and
materials for the construction of an operating "device".
Understanding: great importance is given to the experimental approach
and how to exploit the properties of individual substances and materials
both to confirm what has been studied

Recommended readings


Teaching methods

The classroom lectures led by the teacher are paramount throughout the
course with regard to both the explanation of the basic concepts and the
detailed concepts, that allow the student to carry out and understand the
laboratory experiments on their own.
Practical experiences are made individually.
Discovery oriented teaching. Classroom lectures are mostly held using
blackboard and colored chalk or projection on screen via computer of
diagrams and texts related to the lesson.
