A) Large group expository classes (“CE” in the time tables): Explanation of the theoretical foundations of each topic, complemented by general examples and resolution of exercises related to analytical techniques applied to the analysis of water, food and the environment. These classes will be carried out in person and students will have additional material on the virtual platform of the USC (Virtual Classroom).
B) Interactive classes in small groups (Seminars, “S” in the time tables): The Teacher will provide the student, periodically and well in advance, exercise bulletins and practical cases. The teacher will solve doubts about exercises and will debate with the students in person. The participation of the students is required, since the deliveries of some proposed exercises are part of the continuous evaluation. During the semester they will consider carrying out a small group work and will be exposed in the classroom.
C) Interactive practical laboratory classes: The classes that take place in a practical laboratory are included here. In them the student acquires the skills of working in a laboratory and consolidates the knowledge acquired in the exhibition classes. The student will carry out different experiments in which they will become familiar with the experimental application of the analytical concepts and methodologies explained. The student's personal work, outside the laboratory, of the students in this activity is much smaller. In support of practical teaching, the student will have a laboratory practice manual, which will include general considerations on the work in the laboratory, as well as a script for each of the practices to be carried out, which will consist of a brief presentation of the fundamentals, the methodology to be followed and the indication of the calculations to be made and results to be presented. The student must go to each practice session having carefully read the content of this manual. After an explanation from the teacher, the student will carry out individually or in small groups, the experiences and calculations necessary to achieve the objectives of the practice, collecting in the laboratory diary the development of the practice and the calculations and obtained results. The student will cover a report with this information and the resolution of some questions, for each practice. The portfolio or report will be made individually and will be evaluated by the corresponding practice teacher.
The student will not be evaluated if he does not carry out and pass the laboratory practices.
It is not mandatory to repeat the practices if they were carried out in any of the 2 academic courses prior to the current course and if the laboratory part has been approved.
D) Tutorials in a very small group (“T” in the time tables): Scheduled tutorials, which will mean for each student 2 hours per semester in person. The teacher will guide the student both in global proposals and in specific questions related to the contents of the subject. Activities such as supervising supervised works, clarifying doubts about theory or practices, problems, exercises, readings or other proposed tasks are proposed.
1. The student will not be able to pass the subject if he does not complete and pass the laboratory practices.
2. The evaluation will consist of:
- The written exam that will be taken at the end of the semester and in person. It will consist of a set of theoretical-practical questions and several numerical exercises that cover the different contents of the subject assimilated with the competencies (general and specific) and skills, representing 70% of the overall evaluation.
- Completing and passing the evaluation of the interactive laboratory classes (15 hours) will be essential to pass the subject. The practical grade is 15% of the overall grade for the subject. The practices will be evaluated on the basis of the following three items, each of which represents 5% of the overall evaluation: attendance and completion of the practices, presentation of results (via practice report or similar means) and practice exam. . This exam will consist of questions related to the practices carried out.
- Interest and participation in the expository and interactive seminar and tutorial classes and the completion of some exercises proposed by the Professor during the semester will be evaluated. In addition, the completion and presentation of a work, the ability to speak and write, and the teacher/student debate will be evaluated. The evaluation of these activities represents 15% of the overall evaluation.
3. In the second opportunity, the same evaluation criteria, described in sections 1 and 2, are maintained as in the first opportunity.
4. The evaluation of the knowledge, skills and competencies acquired in the subject will be carried out through the following means:
In the theoretical exam: Know 11, Know 12, Know 13, Know 14. Comp 01, Comp 02, Comp 28
In laboratory practices: Know 16, Comp 05, Comp 06, Comp 10, Comp 11, Comp 18, Comp 20
In interactive classes: Know 15, Comp 03, Comp 06, Comp 07, Comp 11
In cases of fraudulent completion of exercises or tests, the provisions of the Regulations for evaluating the academic performance of students and reviewing qualifications will apply.
It is estimated that in addition to daily attendance, students must dedicate approximately 1-2 hours of personal work per each lecture or seminar hour.

- Attendance at the exhibition classes.
- Previous study and completion of the exercises and questions included in the bulletins that will be delivered prior to the completion of the seminar classes.
- Active participation of the student in the seminar classes and delivery of the exercises proposed by the Professor.
- It is essential to prepare the practices or alternative activity before entering the laboratory. First, the theoretical concepts necessary to carry out each experiment must be reviewed, and then the practice script must be read carefully, trying to understand the objectives and development of the proposed experiment. Any questions that may arise should be consulted with the teacher.
- Consultation of the recommended bibliography.
- Taking advantage of the hours of tutoring during the development of the subject. Those students who encounter significant difficulties when working on the proposed activities should attend the teacher's tutoring hours, in order for the teacher to analyze the problem and help solve those difficulties.
