Learning outcomes of the course unit

Obtaining skills and a practical knowledge of basic operations that are used in the chemical laboratory.

Prerequisites

Successful graduation of Legislation in Chemistry I and Basics of Laboratory Technique.
Knowledge of secondary school chemistry and basic mathematics.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

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.

Assesment methods and criteria linked to learning outcomes

The laboratory notebook (control of preparation), report sheets, tests, style of the work, course-unit credit test.
Evaluation of the test: excellent [100%-90%], very good [89%-80%], good [79%-70%], satisfactory [69%-60%], sufficient [59%-50%], failed [49%-0%]
The average from the evalution of the report sheets, of the tests, of the final test and style of the work is the final evalution of the course.
