The students of the 5th grade under the assisistance of Science teacher Ms Bogusława Tejza conducted the water research.
In order to do it they had taken some samples of water of the Poniczanka, Słomka rivers as well as from the class aquarium and a pond.
Then the students studied their properties and tried to check the water hardness of the samples.
The last activity regarded microscopic examination in order to distinguish distilled water from the water samples.
