With the project Question : Sign?, we are dedicating a wall in the CoSA to visitors' technical and scientific questions. On their next visit, visitors can write their personal questions on a card and give them to the CoSA team. As a thank you, they will receive an exciting experiment to take home.
To answer the questions, we consult with experts from various fields. As drawings, sketches or illustrations, the drawings ultimately become part of a mural that changes and grows over time.
With the participatory project Question : Mark?, the CoSA wants to get in touch with its visitors and find out what people are dealing with on a daily basis in relation to scientific and technical topics.
