Events in Berlin for this Weekend, 20 - 22 June

Friday

Today in the afternoon, you can join Hebrew/German afternoon activity at Bambinim West (Brandenburgische Str), with Inbar Yemini.

Also on this Friday, the "Kinderfest" at the Humboldt University. The event includes all kinds of "academic" activities for children, including a robot stand, a place where you can learn how animals talk and much more.
HU Children Fest, Friday from 3 pm. Main Building, Unter den Linden 6 (Bus 100/200: Staatsoper ; S/U/Tram to Friedrichstrasse)

Saturday: CSD Berlin

Christopher Street Day is the German name for the Pride Parade demonstration for LGTBI rights (after the name of the street where the Stonewall Riots started). The Parade in Berlin has never been blamed of being too prude or modest, so it is left for your consideration, whether or not to participate with your kids: it might has an education value.
CSD Parade, Saturday, from 12:30 from Olivaer Platz to the Victory Column.

Besides, have you seen the nice Google dedication to the day?

Saturday: Fete de la Musique

However, there is another huge event this Saturday! The Fete de la Musique is originally a French event, but Berlin also celebrates it in the past 20 years. Artists - some of them well known like the Element of Crime - perform for free from Saturday afternoon. There is also a specific programme for children, although kids can of course also come to all other gigs. The full programme can be searched by venue, Bezirk or type of event (e.g., for kids)

Also on Saturday

• A street fair on Eosanderstr. 13, to celebrate the 25th Anniversary of the local puppet theatre. 

• Summer fair also at the Archenhold Observatory, with children programme that includes rocket building and other cool activities.
