THE SCIENCE

Behind the Million‑Gallon Curtain

Participants investigate the chemistry and technology that keep aquarium systems healthy, including the nitrogen cycle and the three types of filtration used to maintain a million gallons of water.

THE STANDARDS

Standards‑Aligned Classroom Content

The program is designed to meet Colorado State Standards for middle and high school science—cited specifically in the program materials—making it an efficient field‑trip option for curriculum objectives.

THE INTERACTION

Guided Animal Encounters and Supervised Learning

Students have opportunities to interact with some animals (for example at the stingray exhibit); chaperones are expected to ensure quiet, gentle behavior and aquarium staff reserve the right to limit interaction time if students do not follow guidelines.

What the day feels like

What the visit feels like

The program unfolds as a focused, 45‑minute classroom session that pairs instructor‑led explanation with behind‑the‑scenes demonstrations of water chemistry and filtration. It’s an intensive, curriculum‑tied visit: students move from concept to concrete examples of aquarium systems, with supervised animal interactions integrated where appropriate.

Suitability

Who it's for

Who this program is best suited for, and who should consider alternate options.

1
Middle & High School Science ClassesWell suited — content and activities are aligned to Colorado State Standards for middle and high school science and the program is tailored to grades 6–12.
2
College ClassesAppropriate — the classroom program is available to college classes at a stated per‑student rate and can accommodate higher‑level discussion of aquatic systems.
3
