“Education picnic on the water” was held at the Hydrobiological Station on Saturday (7th May) which was organized jointly with the Masurian Landscape Park. Our guests including children and young people could learn the history of the Station in Mikolajki, see stations laboratories and try to work as a hydrobiologist (sampling, measurements of water parameters), learn to recognize species of water (and not only) insects, look through the microscope inside of a water drop, got to know the natural, historical and cultural values of Mazurian Landscape Park, and admire wildlife photos by Waldemar Bzura (TJ).
