The course uses teaching methods in form of Laboratory exercise - 4 teaching hours per week. The e-learning system (LMS Moodle) is available to teachers and students.

The classified credit is awarded after:
- writing all particular introductory tests - it forms 10% of classification,
- passing all practices and handing particular report till 10th day after the practise - it forms 35% of classification,
- passing self-measurement and handing final report in correct format at the latest in the credit week - it forms 15% of classification,
- successful passing the credit test (minimum score is 60%) - it forms 40% of classification.

11., 12.
Practise: Self-measurement of one type of polymeric material coming from industry using two methods used in practises (no one is absolute) with the aim to identify polymer material of to evaluate difference between "good and bad" material
Output: Coherent and intelligible report from measurement in correct typographical format
13. Credit test

Not applicable.

The aim is to observe and to deduce supramolecular structure of selected polymeric materisals from indirect methods and to demonstrate that final properties of polymer materials are done by supramolecular structure, which can be very easily changed, for example by heating and cooling rates of the melt. Very important part is identification of blank solid polymeric materials by selected method.

The attendance in all practices is demanded. In case of the absence, the practice can be compensated with another group or in the last week of the term. An unexcused absence is the reason for the loss of the credit.
Theoretical knowledge of students regarding the particular practice is examined by the written tests at the beginning of the practice (10-12 questions).
Laboratory report is demanded from each student after each class and handover according to the instructions of a teacher.
