Martenitsa is a Bulgarian holiday centered around the coming of spring. Starting March 1st you wear a martenitsi, a red and white bracelet. It is worn to ward off Baba Marta, a personification of the back and forth between spring and winter. It is worn until you see a sign of spring such as migrating animals or budding plants. Once you see a sign of spring you take off our martenitsi and hang it on a branch.
During the school celebration, grade bands will begin with a presentation by guest speakers in Muir Hall and then each class will craft their own martenitsi to wear while they search for phenological changes with their teachers during Environmental Education.
