General description 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.
Contingency plan 1. Modificación dos contidos. No se realizan cambios.
2. Metodoloxías. Ao tratarse dunha materia do segundo cuadrimestre pódense dar tres situacións diferentes: (A) docencia presencial total, si o acceso ao centro estivera permitido en horario e aforo sen restricións; (B) docencia presencial híbrida, si o acceso ao centro estivera restrinxido en horario e aforo; (C) docencia non presencial, si o acceso ao centro estivera totalmente prohibido. Neste último caso (C), a docencia sería totalmente non presencial.
*Metodoloxías docente que se manteñen. Na situación (A) mantéñense todas.
*Metodoloxías docentes que se modifican. Na situación (B) tanto os seminarios como as prácticas serán presenciais, mais o aforo limitado dos laboratorios pode facer necesario impartir parte da docencia práctica de xeito virtual, realizando actividades alternativas con materiais xerados polo profesorado da materia. Na situación (C), os seminarios desenvolveríanse totalmente online e as prácticas no laboratorio se substituirían por actividades alternativas deseñadas polo profesorado.
3. Mecanismos de atención personalizada ao alumnado. Correo electrónico, titorías por Teams e foros en Moodle, con atención diaria no caso de correo electrónico e foros, e previa petición do alumnado no caso das titorías por Teams.
4. Modificacións na avaliación. Nas situacións (A) e (B), non se modifica nada, a proba mixta será presencial. Na situación (C), a avaliación será non presencial online, baseada nos contidos traballados con todos os grupos de estudantes.
*Observación de avaliación: en todas a situacións mantéñense as mesmas que figuran na guía docente.
5. Modificacións da bibliografía ou webgrafía. Na situación (A) ningunha; na situacións (B) e (C), engadiranse en moodle enlaces a recursos dispoñibles en formato electrónico ou online que puideran ser de libre acceso para todos os estudantes.

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 to be performed individually. The experiments will be indicated in advance in order to prepare both the theoretical background and experimental procedure before going into the lab.
During the laboratory work, the student must show a responsible attitude in relation with both the safety regulations and the methodology and rigour of the scientific method.
The experimental results of each experiment should be analyzed and discussed adequately, being neccesary the use of computer resources.
Each student must hand in a written report of each of the experiments done. This report must contain all the experimental data, its analysis and the critical discussion of the results obtained. The report must be written following the guidelines of a scientific report.
Mixed objective/subjective test Assessment of all the contents worked on the subject, both the theoretical background and the experimental contents, related with the procedure, the analysis of data and the discussion of the results.

Description
Solving any doubts individually and guiding the student in relation to course content.

Part-time students and those with special academic leave permission could ask for presential or email tutorials when necessary.

Assessment
Methodologies Competencies Description Qualification
Laboratory practice A1 A14 A16 A17 A18 A19 A20 A22 B3 B4 B5 C1 C3 The assessment of laboratory practices includes:
1) Continuous assessment of the work done by the student in the laboratory, considering the skills and knowledge achieved, the answers to the questions made during the lab, as well as the experimental data, its analysis and discussion.
The lack of knowledge and/or attitude during the experimental work in the lab will be reason for expulsion from the lab.
It is compulsory to complete the whole period of laboratory sessions to pass the subject.
2) The report prepared for each one of the experiments carried out, which must include all the experimental data, its analysis and the critical discussion of the results obtained. In addition, the report must be written following the guidelines of a scientific report.

Mixed objective/subjective test A1 A5 A14 A20 A21 B2 B3 C3 Written test to evaluate the contents of the subject, both the theoretical background of the experiments and the analysis and discussion of the experimental results.
It constitutes 50% of the final grade at the first opportunity, but students must obtain a minimum of 3.5 points out of 10 in the written test to pass the course.
In the second opportunity, the written test will represent 100% of the final grade.

Assessment comments

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

First opportunity assessment:

The
student pass the subject when the average of the marks obtained in the different methodologies of assessment is equal to or greater than 5.0 points out of 10 and the mark obtained in the written test  is equal or greater than 3.5 points out of 10.

The student fail the subject in case of not achieving the minimum mark in the written test
(3.5), although the average of the assessment methodologies was equal to or
greater than 5.0. The subject appears as failed (4.5).

The final mark could be scaled up to a maximum of 0.5 points as a result of the evaluation of the overall student's progression.

A grade of NP ("absent") will only be given to the students who do not engage in any practice session in the lab.

Second opportunity assessement:

Students who do
not pass the continuous assessment of the practical work in the
laboratory must pass an experimental  test at the lab.

The
students who pass the continuous assessment of the practical work in
the laboratory will have to pass a test in the classroom that will represent 100% of the final grade.

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.

Part-time students and students with special academic permission  (according to the rules of the UDC):

Being an experimental subject, assistance to all activities is mandatory. As far as possible, it will be tried to fit the schedule of the practical sessions to the availability of students.

The evaluation criteria for both the first and the second opportunity, will be the same as for the rest of the students.
