Química

Objectives

This CU is intended for different Engineering courses that require a basic knowledge of Chemistry.
At the end, the students will have developed the ability to understand the structure, properties and transformation of materials, based on the knowledge of how and why atoms combine to form molecules and materials, and how to estimate their properties from
their composition and structure (structure-properties relationships).
This objective is achieved through the inclusion of new and current topics, as well as Case-studies on specific subjects that motivate students to their importance in various areas of Engineering, namely in those related to their respective undergraduate course.

Teaching Methodologies

The teaching methodologies aim to foster learning based on problem solving and on carrying out laboratory work to illustrate the syllabus, reinforcing the practical component, active learning, autonomous work and student accountability. The assessment modelin corporates elements of continuous assessment in the context of active learning (e.g. homework, practical and laboratoryworksheets, etc.) compatible with the significant reduction in the weight of assessment by exams (50%).
