Arecibo Center for STEM Education, Computational Skills, and Community EngagementĀ
Make STEM work for you!
The Arecibo Center for Science Education, Computing, and Community Engagement (Arecibo C3 or AC3) is a science, technology, engineering, and mathematics (STEM) education and research center located at the site of the Arecibo Observatory Historic District, in Arecibo Puerto Rico. AC3 integrates science (ciencia), computing (computación), and community (comunidad) to create a hub for STEM discovery and exploration.
Building a new future upon a legacy of discovery
Arecibo C3 is advancing a new era of science learning at the NSF Arecibo Observatory Historic District. Building on the Observatoryās internationally recognized legacy of scientific discovery, AC3 is transforming this historic site into a modern center where science, computing, and education come together to serve Puerto Rico and the world. Our vision is to expand access to STEM knowledge and skills, ensuring that science and technology continue to contribute to community strength, economic opportunity, and discovery.
AC3 places a strong emphasis on educators and students, supporting learning from middle school through higher education, while also welcoming families, visitors, and lifelong learners. We believe STEM education is most effective when it is practical, engaging, and connected to real problems and real opportunities. At AC3, visitors are invited to explore science hands-on, educators gain access to new tools and approaches, including helping students discover how STEM connects to future college and career pathways.
Our programs in Puerto Rico focus on hands-on learning and real research experiences. These include school field trips that introduce students to advanced biology, computing, and data-driven science, as well as summer science programs that provide immersive exposure to modern laboratory and analytical techniques. AC3 also offers teacher professional development, community-based computing programs, makerspaces, and course-based research experiences that link STEM learning to local environments and challenges. We also aim to provide opportunities that will strengthen STEM communities in Puerto Rico and beyond.
As a growing STEM center, Arecibo C3 continues to develop new programs, partnerships, and public offerings. Rooted in a world-renowned scientific legacy and focused on the future, AC3 is becoming a central hub for STEM education, exploration, and collaboration in Puerto Rico.
