The interactive, digital treasure hunt offers school classes a unique opportunity to explore Berlin and learn more about the history of the GDR. In small groups, students receive clues and puzzles via smartphone, which need to be solved in order to help their friend, art dealer Siegfried Kath, escape to the West. The story is based on true events. The tour goes along the wall strip and takes around two hours. The students can learn something about the history of division on their own in a fun way and experience what it must have felt like to live in Berlin during the GDR era, and the teachers can either also indulge in the fun of playing or simply take a break in the café for a while.

Visit the German foreign intelligence service. At the BND Visitor Centre in Berlin, school classes receive a special tour, during which they learn how the Secret Service works and its control mechanisms. Visiting BND is a quickly sold out and popular activity for school trips to Berlin. During the 90-minute visit, the class experiences a presentation and an interactive exhibition, which vividly presents the tasks and working methods of the BND. This gives students insights into how Secret Service works and what significance it has for the country's national security and democracy. The visitor centre is located on Habersaathstraße in Berlin-Mitte and lasts one and a half hours.

This documentation centre was a detention centre between 1951 and 1990 in the GDR. Today, the area serves as an educational institution that enables school classes to deal with the reasons and conditions of detention. In learning workshops and guided tours, students learn for themselves how pre-trial detention worked in the GDR and what conditions the detainees experienced. Teachers can rely on well-prepared materials that give students an insight into the political system of the GDR and its effects on society. Depending on the activity and topic intensity, the visit, including the learning workshops, lasts between one and a half to six hours and takes place directly in the historic premises of Keibelstraße. The tour alone lasts an hour and a half.

The roof terrace and dome of the Reichstag building offer students an impressive view of Berlin. There are special audio guides for the class, which explain how the Parliament works and how laws are created in a youth-friendly way. Here, students can explore the city and its political institutions from above while strolling through the dome and using the audio guide — allowing them to experience politics at their own pace and for themselves. The experience lasts around one and a half hours and takes place in the Parliament building in Berlin.

There are interactive exhibitions about life in the GDR here. Here, school classes can playfully explore the history of former East Berlin, for example through a Trabi driving simulation and a faithfully furnished prefabricated flat. In this way, students experience everyday life under socialism in an authentic way and can try out numerous exhibits themselves, making this activity an active learning journey into the past. Teachers also benefit from the interactive experience, which they themselves are unable to provide in this form in school, and which ideally stimulates their students' curiosity. The museum is located opposite Berlin Cathedral and the visit usually takes around two hours.
