About Us

That drive to feed students’ enthusiasm is what gave Bridges to Science its start! When Aristy, a data scientist who homeschools her own children, heard that students in her homeschool co-op were requesting courses in programming and robotics, she noticed the glaring access gap that certain communities face when pursuing STEM courses. Most adults in the group did not feel competent enough with the topics to lead the course work, and not all students had the tools needed to pursue them. To fill that void, she began the Katy Math Circle. 

It quickly became evident that the community’s needs for accessible STEM programs were growing beyond the scope of that once-a-week math circle. Bridges to Science was launched to provide year-round programming in math, coding, and robotics to more communities of underserved students in all educational arrangements. 

We maintain the founding principle of feeding students’ curiosity, interests, and love of learning by grounding all programming in hands-on, project-based curricula and providing strong role models for students that might not otherwise see a future in STEM for themselves. 

And our impact goes beyond just education. The course work, which is inquiry-based and project-oriented, cultivates curiosity, confidence, and community in its members. As such, we seek to nurture the bodies, hearts, AND minds of youth in our community. 

“When I see children who are curious and hungry to learn, I want to feed them.”

—Rosa Aristy, founder
