In this activity, participants of the Eco-Club “Blue Explorers” expanded their knowledge by studying about the oceans that form the World Ocean. They learned curious information about the oceans, their location and filled out their names in a map to remember exactly where they are located. The participants found out what the deepest part of the ocean is, who its largest occupant is and what the border between the Pacific and Atlantic Ocean looks like. These presentations were the beginning of a demonstration cycle that we dedicated to the marine inhabitants and their greatest threat-the marine litter.
