  Description
Laboratory practicals 4 sessions of 2 hours of laboratory practice will be developed. See Contents. This activity will be offered under the "English friendly" modality.
Portfolios/Learning folder Portfolio, via institutional moodle, on various food products, in groups of 3-4 people. Each group has to choose at least 1 food. For each product, a file will be prepared that will include: definition and types, composition, nutritional value, properties and quality specifications, according to the model available in the moodle. This information will be endorsed with different documents that will form the portfolio. The exhibition will take place public information on one of the products studied. This activity will be English friendly.
Tutorship of group Group tutorials (3-4 students/group) on the portfolio to be done in the classroom and others places of the Faculty (for example, computer room). This activity will will be offered under the "English friendly" modality.
Lecture Presentation by the teacher of the topics indicated in the Contents section, usually using power point. Master session will be combined with participatory classes with students. This activity will be offered under the "English friendly" modality for some topics).
