Verification of Learning. During the course: observation of the group work dynamics

Individual, final examination: evaluation and discussion of the laboratory reports.

Objectives
As a result of the course it is expected that the students- Are able to evaluate and choose the experimental methods with which to explore a physical phenomenon, demonstrating skills in the planning of experiments;- Have acquired the capacity to use and manage the measuring instruments;- Be able to analyze the results obtained, taking into account the aims of the experiment;- should be able to communicate clearly and without ambiguity the methods used, the results obtained and their conclusions and interpretations.
Contents
instruments, introduction to the theory of errors.
