With birds singing loudly from a large oak tree on the front lawn of Sierra Waldorf School in Jamestown, students and faculty gathered Friday under cloud-speckled blue skies for a Peace Day assembly.

The assembly has been held for more than 20 years in honor of International Peace Day, an initiative by the United Nations started in 1981 and held on Sept. 21. As students first grade through eighth grade sat on the grass, eighth-grade teacher Ginger Rohlen said, “Peace starts within each of you.”

Rohlen and her 15 students organized this year’s assembly. The school choir sang about finding peace. A puppetry performance by teacher Jennifer Aguirre featured an African puppet named Mamba, who told the story of two paintings depicting peace in different ways. The moral was “that peace is not only when there is no trouble, noise or hard work. Peace is in the midst of the way things are when there is calm in your heart.”

Rohlen told a story of a traveling carpenter with tools of love and peace that begins at home.

Each eighth-grader recited a quote about peace by people like Mother Theresa of Calcutta, Gandhi, Maya Angelou, Jimmy Carter, Nelson Mandela and Martin Luther King Jr.

They sang John Lennon’s song “Imagine.”

The assembly ended with the eighth-graders carrying a large paper mache dove and leading the students and teachers to the lower field where they formed a circle, held hands and sang one more song of peace.
