General description GALEGO: Laboratorio integrado con especial énfase nas aplicacións das principais técnicas instrumentais.
Nesta materia afóndase na metodoloxía experimental da Química Física e perséguese que o alumno interprete os resultados experimentais a partir dos modelos teóricos desenvolvidos na materia de Química Física 3. O desenvolvemento dun razoamento crítico que permita integrar o experimento cos fundamentos teóricos constitúe un aspecto de grande importancia na formación integral dun químico. Por outra parte, iníciase o estudante no manexo das técnicas instrumentais máis frecuentes en calquera laboratorio de Química.

ENGLISH: Integrated laboratory with special emphasis on applications of the main instrumental techniques.
The course explores the experimental methodology of Physical Chemistry and it is intended to enable students to interpret the experimental results from the theoretical models developed in the previous course of Physical Chemistry 3. The development of critical thinking that allows integrating the theoretical experiment is a very important aspect in the overall education of a chemist. Moreover, it introduces students to the management of the most common instrumental techniques in any chemistry laboratory.

Methodologies
Methodologies Description
Seminar Practical experiments to perform are proposed. These experiments are related to the theoretical contents of Physical Chemistry 3 subject. Different experimental methodologies are proposed and a specific experimental procedure is discussed.
Laboratory practice Each student is assigned a certain number of practical experiments. Some aspects of these experiments are solved in small groups while others are performed individually.
Supervised projects - The student must analyze the experimental data obtained in the laboratory with the help of software.
- Each student has to make their own lab report containing the theoretical concepts, experimental results and answers to several questions about each experiment. This report must be written following the style corresponding to a scientific report.
Mixed objective/subjective test Evaluation of the contents in the subject. This evaluation will be held upon completion of the practical work.

Assessment comments

Attendance at all seminars and practices is compulsory for the student to pass the course.

First opportunity assessment:

Continuous evaluation of the work done by the student in the laboratory, considering the skills and knowledge, the answers to questions during the development and elaboration of the experimental data, together with the report of practices, constitute 50% of the final mark. A written test will constitute the 50% remaining.

The course is considered passed if the average of the marks obtained in the different activities reaches a minimum of 5 points out of a maximum of 10 points. To pass the course students must obtain a minimum mark of 3.5 points out of 10 in the written test. If the average is equal to or greater than 5 (out of 10) but this threshold mark was not met, the final mark will be 4.5 (fail).

The final mark could be scaled up to a maximum of 1 point as a result of the evaluation of the overall student's progression.

The qualification "not attended" will only be given to those students who do not engage in any practice session in the lab.

Second opportunity assessement:

Students who have successfully completed the lab must conduct a test in the classroom that will account for 100% of the mark.

Students who have not passed the lab are required to perform a practical test in the laboratory.

Students evaluated in the "second opportunity" will only be eligible for
Honors if the maximum number of licenses for the corresponding course
has not been fully covered in the "first opportunity"

Should it be more candidates to honors grade than licenses available, allocation of licenses could be done through a extraordinary exam.

The teaching-learning process, including assessment, refers to an
academic course and, therefore, will restart as new with every new
academic year, including all activities and assessment procedures
scheduled for that course.
