On 28 August from 11:00 to 17:00, children aged four to twelve can try more than thirty experiments and conversations at Lange Voorhout. Places are free but should be reserved.

What you need to know

A large science day can easily become an adult-led race between queues, while children remember little beyond waiting. Expeditie NEXT spreads more than thirty activities across Lange Voorhout in Den Haag on 28 August. Children can generate energy with their bodies at Batterijhelden, explore how people develop in the Sociaal Lab, play with language through Kletskoppen and meet presenters including Klaas van Kruistum, Tirsa With and Sterrin Smalbrugge. The main audience is ages four to twelve; hours are 11:00 to 17:00 and free places require reservation. Hokimi suggests letting each child choose one thing to build, one person to question and one demonstration to observe. Three deliberate encounters plus a proper lunch break often create more discovery than completing a programme grid. Missing a full session should never become proof that curiosity failed.



  • The science day runs on 28 August 2026 from 11:00 to 17:00.
  • It is at Lange Voorhout in Den Haag and mainly serves ages four to twelve.
  • More than thirty experiments and activities are planned.
  • Places are free, but reservation through the official page is advised.


Hokimi field note: Reserve, then circle three activities of different types. Bring water, snacks and something to sit on. Set a limit for queues and move on when it is exceeded, so children keep agency over the day.
