Planning your visit

Most visitors spend between one and a half and two hours at the Museum, although many mention they wish they had allowed more time. The exhibits and science demonstrations are geared for school-age children through adults.


The building is accessible to those with special needs, and assisted listening devices or captions are available for most films.
