Sally Ride Science

I had never heard of this program before when I came across it.  Your kids can go to these camps once they are in upper elementary or middle school. 

Here is some info I found on their website:

Sally Ride Science™ is an innovative science education company dedicated to supporting girls' and boys' interests in science, technology, engineering, and math. The company, founded by Dr. Sally Ride, creates programs (including the Sally Ride Science Academy for teachers) and materials (including STEM career books) that bring science to life for students, their parents, and their teachers.
