Aquaponics session highlights nitrogen cycle and hands-on learning for teachers
Summary
An aquaponics session at the conference demonstrated how fish waste can be used as plant fertilizer and described pumps and nitrogen conversion as a classroom-ready system for teaching ecology and systems thinking.
The aquaponics session presenter described the system as one "where it uses the fish waste or ... fertilizer to feed and fuel the plants," and explained the system uses pumps and a biological conversion of ammonia into forms of nitrogen that plants need to grow. The speaker characterized the workshop as highly visual and hands-on, useful for teachers who learn by seeing systems in action.
The session was presented as an example of project-based STEM learning that ties biology, chemistry and engineering together. Presenters suggested aquaponics activities could create 'wow' moments for students and be adapted as classroom demonstrations or school garden projects.
