Objectives
Acquiring basic knowledgement of Chemistry that may be applied in further Engineering studies and that allow an understanding of fundamental chemical phenomena with impact in society.
Acquiring skills for the resolution of chemical problems.
Acquiring calculus skills regarding chemical phenomena.
Development of the ability to criticise the plausability of obtained results.
Development of team working skills in the laboratory.
Prerequisites
Three laboratory sessions must be completed together with the respective answers to group questionnaires and a good performance during the lab work.
A minimum attendance of 2/3 of the problems (TP) classes. There are 7 TP classes, and the student is only allowed to miss 2.
An average of 9.5 (in a scale of 0 to 20) in the average of the 2 tests or in the final written exam.

Teaching method
The methos of learning include: first by exposing the theoretical contents using datashow; second, in the problems classes, students are encouraged to solve chosen problem situations, to aim the perception of the difficulties that make them think and criticise obtained results; third, in the lab classes, students have the opportunity to perform experiences where they can consolidate knowledge acquired in the other classes; fourth, the use of web site of the course that includes material for study; fifth, personal contact.
Evaluation method
Tests and/or final written exams.
