At the Natural History Museum they offer children the opportunity to dig for fossils (click on ‘Education’ and the ‘English’ button). The sight of a group of children dressed as archaeologists with trowels in hand, waiting to uncover their first fossil, makes for a cute photo shoot!
More dressing-up is available at Schloß Charlottenburg where children travel back in time to the 18th Century
From the 18th to the 21st Century now, how about visiting Dimension Alley, a 3D Printing Café in Prenzlauer Berg.
Berlin is a marvellous back-drop for any occasion but specifically, there is an organization called ‘Wir Sind Berlin’ who will provide tours for children with titles like ‘Treasure Hunt in Old Berlin’ or ‘Let’s Roll’ which includes transport on scooters (not for the faint hearted parent that one!).
