Most of the Museums are free for people younger than 18 anyways. But for adults the Museum pass is a great advice.

The Futurium is a quite cool new Museum. Located close to the Hauptbahnhof (Berlin Main Station). Its for free. Its a Museum about the future with lots of interesting stuff on for example future of medicine, future of transport and so on. It has a positive view on many topics even though it of course adresses also the problems. Just super cool and very interactive.
