5.1. Methodological overview

DISCLAIMER

The English version is a translation of the original in Spanish for informational purposes only. In case of discrepancy, the Spanish original shall prevail.

The learning process designed for this course is based on:

This course is divided in 40 lectures of one hour each, 8 hours of problems, 10 hours of laboratory and 25 hours of supervised work, distributed as indicated in the following section.

The course material is uploaded in the ADD of the University of Zaragoza. Thus, the student can review it in detail before and after the class. The material that is left available to students includes presentations of the theoretical concepts, as well as a collection of problems. In addition, students will be provided with the practical guides needed for the laboratory.

Attendance in lab is mandatory.

Supervised work will take place at the premises of the Department of Applied Physics, at a time previously agreed between students and teachers. In case of non-attendance the student will have to take the full final exam.

5.2. Learning tasks

The program offered to the student to help him to achieve the expected results includes the following activities

Block I

Teaching and learning activities: 3.8 ECTS in total.

-Class attendance: 26 hours of lectures plus 5 hours of problem solving

-Lab: 6 hours.

-Supervised work: 12 hours divided in:

-Information search.

-Interpretation of work protocols in Spanish and English

-Answer to issues raised while doing the work.

-Lab report submission.

Competences: In addition to those described in paragraph 3 as generic, the student must acquire during this block the following competences:

- To know the physical fundamentals of dynamic models applicable to texture analysis and rheology of food, and which are the basis of the 2^nd year course “Análisis físico y sensorial de los alimentos”.

- To take measurements of properties of solids and liquids, and calculate the error of measurements, as a critical foundation of the reports made in each case.

- To learn to present and defend those reports.

Assessment: See the corresponding section.

Block II

Teaching and learning activities: 2.3 ECTS in total.

-Class: 14 h of lectures plus 3 hours of problem solving

-Lab: 6 hours.

-Supervised work: 13 hours of teamwork under the supervision of the teacher:

The first part will consist on the corrections of the lab reports from his classmates.

The second part will consist in analysing the data obtained in the lab 6 and later do an oral presentation of the results.

Competences: In addition to those described in paragraph 3 as generic, the student must acquire during the block the following competences:

-          To know the physical fundamentals of Thermodynamics and Optics applicable to thermo-mechanical and optical states of food analysis, which are needed for the 2^nd year course  “Análisis físico y sensorial de los alimentos”.

-          To learn to speak in public and to correct reporting practices.

-          To learn to analyse many experimental data using statistical techniques, thus approaching a real situation of industrial control laboratory or research.

Assessment: See the corresponding section.
