In the framework of the 4th National Conference “Biology in Education”, the Greek Bioscientists’ Association organized the National School Poster Competition “The past, present and future of Greek seas”. The main aim of the competition was to raise students’ awareness regarding marine environment and marine life while encouraging the production of original works depicting the way students see the connection of the Greeks to the sea. More than one hundred students from all the country participated and five posters were awarded prizes. Congratulations to our C class student Vasiliki Chani whose poster was among the five to win.
