Hold a small memorial service?
We (approximately 24 students from grades 9-11) are going on a trip with French students where we will visit various Holocaust memorials, e.g. Mittelbau-Dora, Roter Ochse in Halle.
And there at the Red Ox, we're supposed to hold a memorial service at the guillotine. About five minutes. Just something small and simple. Maybe someone here has an idea for that.
