Objetivos

-Give the student a broad view of the fundamentals of Chemistry, within the scope of their basic scientific training: 
 
-Knowing the atomic structure;
-Be able to write the structure formula of a molecule, identify its geometry and respective polarity;
-Know the concentration units of solutions;
-Perform stoichiometric calculations, determining the amount of reagents needed and products obtained;
-Establish the difference between irreversible reaction and chemical balance and know the various types of chemical balance: acid-base balance and solubility balance;
-Perform pH calculations of acid and base solutions (strong and weak);
-Determine the solubility of a poorly soluble substance;
-Recognize the importance of redox reactions and identify the species involved.

Resultados de aprendizagem e competências

The UC covers basic concepts of Chemistry, from Chemical Bonding to various forms of Chemical Equilibrium, thus covering the fundamentals needed to understand Environmental Chemistry (environmental analysis, Chemistry involved in natural systems and treatment systems.

The UC has a laboratory component that allows, in accordance with the objectives of the UC:
-operationalization of the concepts taught;
-development of the scientific and experimental spirit and the ability to organize and analyze information;
-learning of laboratory and analytical procedures and techniques (later applied in specialty UCs);
-acquisition of "know-how" skills and teamwork.

Métodos de ensino e atividades de aprendizagem

Classes have a theoretical-practical (and not theoretical) typology, since it is a CU with the objective of operationalizing concepts. The participatory expository method is adopted, and interactive training is privileged even in the introduction of theoretical concepts. It seeks to lead students to draw conclusions, guiding them in this process.

 The UC has a laboratory component, intending to illustrate in practice the theoretical concepts transmitted. In laboratory classes, students carry out experimental work according to provided protocols, later preparing the respective questionnaire or report. In these classes, the experimental and collaborative method (group work) is put into practice.

Distributed assessment with final exam

THEORETICAL NOTE
Approval in the theoretical component can be obtained by continuous assessment (2 tests) or by exam Evaluation by tests:
1st test: 28 Nov
2nd test: 23 Jan

The student whose arithmetic mean of the tests is greater or equal to 9.5 val., provided that in none of the tests the classification was lower than 8.0 val.


Assessment by exam
To be carried out on the dates set by the CP and contained in the SI 

The student whose grade is greater than or equal to 9.5 val will be approved. 

LABORATORY NOTE

The laboratory component consists in the presential assessment (attendance, laboratory preparation and group work) and a final written assessment of the contents worked in the various laboratories.

The student must have a minimum of 8.0 val.

Laboratory evaluation: 28 Jan

FINAL GRADE

The final grade is the weighted average of the theoretical grade (70%) and the laboratory grade (30%)

Fórmula de cálculo da classificação final

The final grade is the weighted average of the theoretical grade (70%) and the laboratory grade (30%)

Provas e trabalhos especiais

The laboratory component consists in the presential assessment (attendance, laboratory preparation and group work) and a final written assessment of the contents worked in the various laboratories.

The student must have a minimum of 8.0 val.

Avaliação especial (TE, DA, ...)

Worker-Students (with recognized TE status) who cannot attend laboratory classes will have an final written assessment, to be held in a date to be scheduled, in order to obtain classification in the laboratory component.

Melhoria de classificação

Performed only at appeal time

Observações

-In line with the decision of the Pedagogical Council, to carry out the UC in continuous assessment, the Student must have a minimum frequency of 75% of TP classes. 

-Without attending laboratory classes and completion of the final written assessment, the student will not have approval.

- A MAXIMUM of 1 absence from laboratory classes is allowed.

- In case of suspected fraud, the procidure is in accordance with the Despacho nº 40 /Presidente/2021
