In 2022, the European Commission launched its competition Expertiment for the Classroom. This competition asked teachers from across Europe to team up with leading researchers funded through the Marie Skłodowska Curie Actions and co-create learning material based on cutting-edge research. Over 500 researchers and teachers took part, and more than 100 excellent proposals were submitted to our international jury. 

After long deliberations, the jury selected the three best proposals. Spacebound: the lost astronomer was one of them. We hope you enjoy this creative and simply wonderful activity for your classroom.
