Do you have a local science center similar to our Carnegie Science Center?
Have you checked your local colleges and universities for outreach programs?

This is a really cool local program for girls. Maybe you can find something similar in your area... http://canteengirl.org/exploreyourfuture/tours/future-tours/
There is also a website by the Carnegie Science Center that currently seems to be out of order. Maybe try back at another time. www.braincake.org
