Exploring Environmental Systems in Action at Biosphere 2

From Rosalyn Manio, Upper School Biology and Environmental Systems & Societies (ESS) teacher: From February 18–20, my Grade 11 ESS classes had the exciting opportunity to travel to Arizona for an educational visit to the remarkable research facility known as Biosphere 2. The trip was designed as an immersive learning experience connected to our studies in environmental systems, sustainability, and scientific inquiry.

Our journey began very early on February 18, when we met at the airport in Washington, DC for our flight to Arizona. After arriving in Phoenix, we traveled to our accommodations and received an orientation about the trip, including expectations and the learning goals for our visit. Throughout the trip, we were expected to demonstrate the values of the IB Learner Profile — being responsible, respectful, and engaged learners. 

The highlight of the trip was our full-day academic visit to Biosphere 2 on February 19. Biosphere 2 is a large research facility designed to study ecosystems and the interactions between living organisms and their environments. Scientists use the site to better understand Earth’s systems and how humans can live more sustainably.

During the visit, we participated in guided tours and inquiry-based learning activities. These experiences allowed us to explore how controlled ecosystems are maintained and how researchers study environmental processes. We also took part in structured reflection activities connected to IB Approaches to Learning, encouraging us to think critically about what we observed and how it relates to real-world environmental challenges. 

Throughout the tour, we explored several fascinating parts of the facility:

• Geodesic domes and research structures that house different ecosystems.
• Controlled environments used to study climate, water cycles, and ecological interactions.
• Experimental areas where scientists simulate environmental conditions and monitor ecological changes.

One of the most impressive areas was the large dome structures (The Lung) that form the iconic skyline of Biosphere 2. These structures allow scientists to recreate and study ecosystems in a controlled setting.

The photos from our trip capture both the scientific environment and the memorable moments we shared as a group.

• Group photos outside Biosphere 2 show our class standing together with the famous glass pyramids and domes behind us. The bright Arizona sun and desert landscape made for an incredible backdrop.
• Indoor group photos capture us inside the facility near one of the large research exhibits, highlighting how closely we were able to observe the scientific work happening there.
• One image shows a large white geodesic dome, one of the structures used for environmental research.
• Another photo captures a unique solar-panel “tree” structure, demonstrating innovative renewable energy technology used at the site.
• A particularly interesting picture shows a water research area inside the facility, where aquatic environments are carefully maintained for scientific study.

These photos not only document the scientific spaces we explored but also the collaboration and excitement of learning together outside the classroom.

This trip helped us understand how complex environmental systems work and how scientists study them to address global challenges such as climate change and sustainability. Visiting Biosphere 2 allowed us to experience environmental science beyond textbooks and see how interdisciplinary research can contribute to a better understanding of our planet.

It was not only an educational experience but also a memorable opportunity for our class to learn, explore, and grow together.
