One of the purposes of science centres is to present science and research to visitors. This makes them a very good venue for both tours and open house events. But you should remember that many people may have already visited the science centre and it may be in an out-of-the-way location.
Target Group: Broad with particular emphasis on younger visitors.
Preparations: Make sure staff members are available; come up with a special theme to focus on; inform people that they will have access to a different part or aspect of the science centre when they attend an open house or tour, and market the activity.
Challenges: Getting the information out.
Benefits: These facilities are created for the purpose of communicating science in an attractive and interesting way.
