Field trip. Zisimou Eleni, Primary school of Kardamaina, Kos
We went to the port of Kardamaina and, together with the team from the university, we measured the sea pollution using the Secchi disk. We learned about marine species and how they are at risk of extinction. We then went to the beach, and after sifting the sand and observing the main types of litter, we cleaned the area.
