Students in the 3rd grade welcomed the “Agents of the Planet” and author Eleni Andreadis and presented to an audience the “secret mission” they had undertaken. Their dance and songs on environmental protection moved the author, and all who attended the performance gave the students loud applause. What happened next, however, was even more ecological, as the students went to the schoolyard and, by reusing plastic caps, they built their ecological “footprints!” Students in the 4th grade, as new “agents,” successfully completed another mission that was assigned by “Perivalontopol Headquarters.” With the help of the amazing secret agent, Mark, they learned how to protect the forest, and promised to remain vigilant guardians during the summer period. All children spent a day full of fun and were educated on environmental issues.
