The course includes a 30-minute multimedia presentation and one hour laboratory class. The presentation concerns the main parameters that can be measured in the fresh and sea water – ammonia, nitrites (III), nitrates (V), phosphates, salinity and water hardness, as well as the role of these parameters in the aquatic environments. In the practical part of the class, students measure parameters for two types of samples –seawater (from the Baltic) and fresh water (from the aquarium). Analyses are conducted in groups and every group works on different type of measurement or sample. At the end of the class, all the obtained results are compared and discussed. Students have to consider correctness of their results and possible causes of any deviations from the norm. Example definitions and processes which are introduced during the class are: eutrophication, nitrification, osmotic water, salinometer.
