Abstract | Alternative farming techniques are often more efficient and conserve resources more effectively than conventional farming, which can harm the environment with pesticides and synthetic fertilizers (Pimental 2005). To learn the theory, application, and related science concepts of sustainable farming techniques, students can collaborate to create an alternative farming system in the classroom. This article describes a unit on aquaponics, a soilless method of farming that blends aquaculture and hydroponics. A symbiotic relationship forms between fish and plants to create a healthy system for farming with minimal water usage through a recirculation system. A simple aquaponics system consists of a fish tank with live fish beneath a plant grow bed. A small aquarium pump moves water from the fish tank up to the plant grow bed, and then gravity returns it to the fish tank, making a continuous cycle. The authors developed this lesson for a ninth-grade biology class, but it can be adapted to any grade level. (ERIC). |
