The purpose of the experiment, according to teacher Katrin Riekermann, was to have the girls walk around the town centre to see if they felt discriminated against while wearing a headscarf. The children found locals did treat them differently, with the German broadcaster reporting that for Lünen residents, women in headscarves is an ‘everyday’ sight.

Celina Lebsack, 15, was one of the volunteers and claimed that she felt no discrimination by local residents, but worried that her friends might recognise her while she wore it.

The “experiment” is not the first time school children in Germany have been asked to put themselves in the shoes of those from foreign backgrounds. In 2016, a school just outside the German city of Schwerin put students on an island and told them to become asylum seekers.

The “Refugee for the day” project, which was spearheaded by pro-migrant group Network Working for Refugees (NAF), put the children through meetings with stern border guards and attempted to emulate the process of claiming asylum. One participant, a 16-year-old named Gord, said the experience was not enjoyable and claimed he would rather help asylum seekers in a more practical way.
