Objectives

Physical Chemistry is a very important subject dealing with the physical principles underlying the properties of chemical substances.The aim of Laboratórios de Química-Física is to place the theoretical abstract concepts into an experimental context. Some of the goals of this subject matter are to: (a) expose students to rigorous experimental methods which emphasize the classical physical chemistry concepts; (b) help students to develop important experimental skills; (c) train students to observe experiments, keep records of the observations made and analyse the data critically; (d) teach students to present experimental results and write reports clearly, concisely and consistently.

Teaching methods and learning activities

Each group of 2 students will conduct 5 experiments, one in each area of the subject matter, according to a pre-established calendar.
Students are expected to conduct the experiments with minimal assistance of the lab responsible.
The experiments should be prepared before beginning the experiment. The experiment preparation and record keeping must be done in a dedicated laboratory notebook. At the end of each experiment a data sheet must be filled and delivered to the lab responsible. However, all data must be safely recorded in the laboratory notebook.
After completion of the first experiment, each group will present a 15-minute oral report to the rest of the class. The students should use the adequate media tools (Power Point, overheads or chalkboard) for this presentation.
After completing experiments second to forth a short report (Abstract, Results, Discussion and References) in each experiment must be written, with 4 pages maximum. Discussion must be clear and to the point, not long, 1 page maximum. The deadline for report completion and delivery is 1 week; a new experiment could only begin once the report of the previous is delivered. Late reports will not be accepted.
After completion of the fifth experiment each group will produce, display and present a poster with the obtained results.

Software

Word processor. Spreadsheet program. Information manager and communication program. Presentation graphics program (Power Point, Netscape Clipper, or similar)

Evaluation Type

Distributed evaluation without final exam

Eligibility for exams

Effective completion of the 5 experiments and corresponding reports. Correct maintenance of a laboratory notebook.
No other criteria available (cf. Art.4, n. 3 d).

Calculation formula of final grade

Experiment Reports, 80%; Global Laboratory Skills, 20%.

Examinations or Special Assignments

Not applicable (cf. Art. 5º, n. 6).

Special assessment (TE, DA, ...)

Not applicable (cf. Art. 10, ns. 2 e 3).

Classification improvement

Completion of an independent experimental project, to be defined, with the corresponding report and final discussion on any topic of the subject matter.

Observations

Any occurrence falling out these regulations should be submitted to the prime responsible of the subject matter and handled within the regulations in existence.
