Jörg Stahlmann, Vice President for Administration and Finance, welcomed the children and young people to the Haarentor campus in the library hall. In Wechloy, Prof. Dr Esther Ruigendijk, Vice President for Young Academics and International Affairs, welcomed the participants.

A total of four boys learnt how a scanning electron microscope works at the Institute of Chemistry and Biology of the Sea. To do this, they made specimens - including some of their own hair - gold-plated them and then looked at them under the microscope.

Who has the thickest hair? The boys were also able to measure this precisely with the microscope.

A brief history of the universe: in the astrophysics workshop, eleven boys and girls looked at the most important events since the creation of the universe.

Dinosaurs? Humans? The formation of the earth? The pupils not only had to find the right pictures for the texts, but also put the events in the right order. Afterwards, there was an exploratory tour of the university's observatory.

How do you read an ECG? That's what the participants learned in the workshop at the Clinical Training Centre. The students were also able to try out how to perform an ultrasound scan, how to take blood samples and how to resuscitate a person.

In the bookbindery, two girls learnt about the process of creating a book.

Gluing, folding, pressing - the girls were able to get a taste of the various everyday tasks of a bookbinder.

What does your brain do? In the Department of Psychology, the boys and girls looked into this question and learnt, among other things, how an EEG is recorded using a special cap.

After an introduction to magnetic resonance imaging, boys and girls were able to work in separate groups on various methods that can be used to record and measure brain activity.
