Objectives

This course is a continuation of Chemistry I. Chemistry is the study of matter and the changes it undergoes. A 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. The 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 the 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 behavior 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

Specific skills:

- 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.

 

Transversal skills:

- 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 correct and clear way;

- Learning to learn; - Build a positive attitude to science; - Ability to work in team; - Compliance with deadlines

Teaching methods and learning activities

Theoretical-practical classes:

Help to strengthen the understanding of concepts approached in theoretical classes with exercise solving.

Practical classes:

With the laboratory component to be developed in practical classes we aim that the student:

- learns how to work safely in a laboratory;

- learns how to correctly manipulate simple scientific equipments and do laboratory experiments on chemical fundamental concepts;

- explains the experimental observations according to the basic laws of chemistry.

Eligibility for exams

For the ordinary evaluation students, the attendance of laboratory classes is compulsory (75% Min). It also requires a minimum mark of 8 values in the individual laboratory evaluation and a minimum mark of 8 values in the TP component.


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

Calculation formula of final grade

Final grade = 0.70 * (grade of the theoretical component) + 0.30 * (grade of the practical component)

The assessment of the theoretical component (TP) consists of taking an exam, in the period allocated to exams at the end of the semester.


Evaluation of the practical component:

In laboratory classes students will carry out the assignments individually 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 is required a minimum mark of 8 values in the individual laboratory evaluation.

Special assessment (TE, DA, ...)

The students can choose between an evaluation similar to the ordinary students’ one or a 2hour laboratory practical exam (minimum of 8 marks; 20%) and a 2h written test without consultation (minimum of 8 marks; 80%).

Classification improvement

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.
