Primary schools challenge CERN

CERN scientists have six months to find out what’s inside two mysterious boxes without opening them!

Wednesday, 30 June 2021


As the Be a Scientist project reaches its 10th anniversary, the tables are turned as primary school pupils set a challenge for CERN… and the clock is ticking!

Pupils from Jean de la Fontaine (Prévessin-Moëns, France) and Cérésole (Petit-Lancy, Switzerland) schools, who participated in the Be a Scientist project in 2020/2021, have invited the CERN community to take up the mysterious boxes challenge. In the utmost secrecy, the pupils have hidden various objects in two boxes, which they hope will give scientists a hard time and keep them busy for the next six months!
