My friend Isabel and her grandchildren wanted to spend the day at the Children's Science Museum at the Expo Center in Lisbon.  The architecture and design was spacious and well done.  The exhibits are on three different floors.  The exhibits are much like the ones at the Exploratorium in San Francisco.  The children interact with things that explain it's properties and how things work.  It also lets the participants use ways of solving ideas.  There is also a Crime Scene exhibit that explain the use of deduction and science to find the criminal.

The photos are of the front, entry, the children riding a bicycle, balanced on a single rope with a weight on its bottom and signage for male, female and wheelchair access to the bathrooms.
