The most important subjects in school “are art, PE and music. That is where creativity and the joy of letting off steam are stimulated, and this joy is what you also need in the STEM subjects,” says physicist Harald Lesch. This workshop is therefore an invitation for creative letting off steam while, seemingly incidentally, fostering practical skills. Because where else do children have the opportunity these days to try out and discover being a tradesman and problem-solver? And keep the results of their activities in their hands.
