Objetivos

Acquisition of knowledge and development of skills and competences for classic analysis to water and food and their interpretation of results according to applicable normatives or standards.

Resultados de aprendizagem e competências

By understanding the principle of the method the student can apply it in various contexts and samples. The interpretation of the results in the light of environmental and food standards makes it possible to achieve the ultimate objective of the ability to analyse in laboratory terms the quality of environmental and food samples.

Practical contents
Examples of possible laboratory analyzes associated with theoretical content:

Practical Content: Some of the following laboratory analyzes associated with the theoretical contents: -Analysis of water quality and bottled: Suspended total, pH, conductivity, color, smell and flavor, alkalinity, hardness, chlorides, color and turbidity Residual chlorine.
-Analysis to food such as meat products, fish, milk and dairy products, juices / refrigerants, wines, cereals, rations: humidity, dry matter, ashes (various foods), suspended solids, density and pH (beverages), granulometric analysis (cereals) , Sensory analysis (meat), acidity (milk), determination of salt content - chlorides (bread, instant masses, toast).

Métodos de ensino e atividades de aprendizagem

In theoretical-practical classes, concepts are taught with the aid of slides and exercises related to each parameter are solved.
It is intended, however, that the approach is very practical, so a great focus is given to the laboratory component of the discipline.
In laboratory classes, the parameters studied are determined in various types of environmental samples (consumer and waste water) and food.


The knowledge is learned in TP classes and applied over time with laboratory work and respective reports.

Tipo de avaliação

Obtenção de frequência

In order to pass the course, a minimum grade of 9.5 points is required for the laboratory practice component and a minimum grade of 9.5 points for the theoretical component.

Final Grade = 65% theoretical grade + 35% laboratory grade

Theoretical Component
It can be carried out by continuous assessment (1) or final exam (2)
(1) Continuous assessment: 70% minimum attendance -> 2 tests. In the 1st exam period, the student can make the recovery of one of the tests (or exam if you prefer)
(2) Final Exam: 1st season and Appeal

Practical Component (Laboratory)
- Can only be performed by continuous assessment: mandatory attendance.
- The evaluation is made by the reports/questionnaires/posters delivered within the stipulated deadlines as well as 1 oral discussion of reports (grade from 1 to 5, later converted from 1 to 20, max. 20% lab grade).
Comments:
- there is 1 recap class to complete missing work, the absence of a data processing class implies the delivery of an individual report with a set of data provided by the teacher
- each day of delay in the report delivery deducts 1 value
- extra/optional: the performance of 1 volunteering action in the area of ​​the course is valued (corresponds to the equivalent of an extra report, with a classification of 20 values ​​that enters the average of the practical component).

The Professor reserves the right to, in specific or general cases, carry out an EXTRA oral test on theoretical or laboratory subjects, with the final grade of the component being: 50% oral test + 50% written elements (tests, exams or reports). The oral test will be carried out in the presence of at least two teachers.

Fórmula de cálculo da classificação final

In order to pass the course, a minimum grade of 9.5 values is required for the laboratory practice component and a minimum grade of 9.5 values for the theoretical component.

Final Grade = 65% theoretical grade + 35% laboratory grade

Avaliação especial (TE, DA, ...)

Working Students, High-Competition Athletes, Associative Directors and Students under the Religious Freedom Law must send an email to the Teacher at the beginning of the semester (until the second week), to present their relevant specifics, under the terms provided for in the respective diplomas.

Any impediment to the presence in laboratory classes, evaluation moments, etc., must be communicated as far in advance as possible, in order to make it easier to find a close solution (instead of solving only at the end of the semester, in the recap class, etc).

Melhoria de classificação

In second season exam

Observações

For students who intend to carry out continuous assessment, theoretical-practical classes (TP) have a mandatory attendance of 70%.

Laboratory classes are mandatory, with a recap class at the end of the semester to complete (1) any missing work.

The Environmental Analysis course has 6 ECTS, corresponding to 150 h. The course has a total of 5 hours per week, 75 hours of classes per semester. The remaining 75 hours are devoted to the preparation of reports, questionnaires and posters, study for tests or final exam.

-Clarification of Doubts
IMPORTANT: Students who wish to clarify doubts should send an email or contact  the teacher/s 

- Support materials (slides, laboratory protocols, etc.) can be found on Moodle 

-The use of cell phones during classes is prohibited, unless expressly indicated by the teacher.
