Objectives

Chemistry is the study of matter and the changes it undergoes. Basic knowledge of chemistry is essential for students in many areas because chemistry is a science that is of vital importance to our world, whether in nature or in society. Chemistry has been, and remains, a principal agent in all areas of science and technology. In fact, chemical research and development in recent centuries have provided new materials that profoundly improved our quality of life, and helped advance technology in many ways.

OBJECTIVES Review and develop a clear and fairly comprehensive basic principle essential to the rational understanding of the physical and chemical behaviour of matter. Show the importance of chemistry in all its aspects: life, industry and society. Awareness, motivate and develop skills to work in the laboratory: correct handling of materials, equipment and simple experimental techniques.

 

Learning outcomes and competences

As a result of learning, students should be able to:

- Observe a chemistry situation and describe it correctly;

- Using the relationships between concepts (mathematical or otherwise) to a chemistry situation;

- Structuring relations between concepts of chemistry;

- Carry out experimental essential operations;

- Perform laboratory rigs in chemistry with dexterity and autonomy;

- Working in a chemical laboratory, following the safety standards for the handling of reagents and procedures.

 

As general competence students should also be able to:

- Organize, interpret, evaluate and criticize data, results and procedures;

- Understand the information transmitted in oral speech and written texts,

- Communicate scientific information and knowledge in a correct and clear way;

- Learning to learn;

- Build a positive attitude towards Science;

- Ability to work in a team;

- Follow deadlines

Teaching methods and learning activities

The fundamental concepts are taught in lectures using slides containing preferentially figures and graphics to illustrate the concepts. Problems covering all topics in the syllabus are discussed and resolved.

In the laboratory classes is intended that the student:

- Learn to work safely in a laboratory;

- Learn how to correctly manipulate scientific equipment and perform simple laboratory experiments on the fundamental concepts of chemistry;

- Explain the experimental observations according to the basic laws of chemistry. The laboratory program will consist of: a) Determine masses / prepare solutions b) Determine volumes / dilute solutions c) Perform and identify various chemical reactions

Eligibility for exams

For the ordinary evaluation students, the attendance of laboratory classes is compulsory (75% Min). The tolerance to enter laboratory practical classes is 10 minutes, with no longer delays allowed. It also required a minimum mark of 8 values in the individual laboratory evaluation.

The tolerance to enter laboratory practical classes is 10 minutes, with no longer delays allowed.

Calculation formula of final grade

Final Grade = 0.7* (theoretical component) + 0.3*(practical component)

The assessment of the theoretical component consists of carrying out, in person, two mini-tests with equal weight in the assessment (50% x 2). These two mini-tests can be replaced by a single global exam at the time of Appeal. It requires a final minimum mark of 8 values in the TP evaluation.

Assessment of the practical component:

In laboratory classes students will carry out several experiments and will have to submit two reports of two practical assignments to be defined, being delivered in the class following its completion. The report can only be done by those who attended the class.
The grade of the practical component will be distributed as follows:
20% - Continuous individual assessment in laboratory class;
40% - evaluation of two reports referring to 2 practical assignments;
40% - individual practical assessment, with theoretical issues taught in practice. Each student will be assessed individually in the performance of the same work. It requires a minimum mark of 8 values in the individual laboratory evaluation.

Special assessment (TE, DA, ...)

The students may choose either to be assessed as regular students or to do both a laboratory practical exam lasting 2h (minimum required: 10 marks; 20% of the final mark) and a written test lasting about 2h (80% of the final mark).

Classification improvement

The students can improve their classification by enrolling under the deadlines.

The theoretical component can be improved by doing a written test (approx 2 hours) and the practical component through the frequency of the practical classes of the next school year.

Requirements: Basic knowledge of chemistry acquired in secondary school.
