2. Célkitűzések és tanulási eredmények
2.1 Célkitűzések
The aim of the course is to introduce the characteristics and operation of the aquatic ecosystems to the students and moreover to teach them how engineering activities affect aquatic ecosystems. During the laboratory exercises, the students gain basic skills in determining certain water quality parameters, and during aquatic biology exercises they can gain insight into the life of natural waters and the diversity of microscopic organisms by using microscopes.

3. A tanulmányi teljesítmény ellenőrzése és értékelése
3.1 Általános szabályok
The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via two written tests and the written exam.
Final grade for the course is offered based on the two midterms. If the student accepts this grade, this will be his/her final grade, he/she does not need to take the written exam. If the student wants to change the offered grade (based on the two midterms), it is possible by taking written exam.
