SIC Cool Project: Aquaponics at Fulton High School
By: Jeremy Winsor
High school students at Fulton Schools are gaining a deeper understanding of biogeochemical cycles and water chemistry using aquaponics. Students developed their own mini-systems using aquariums, foam raft style grow beds, and several varieties of plants and aquarium fish. These mini-systems allow students to actively analyze pH, nitrogenous wastes, temperature, carbonate hardness, general hardness, dissolved oxygen, and a variety of other elements. The mini-systems are being used as a model for data collection and recommendations for a larger system. Students spent the fall constructing the large system that is currently housing rainbow trout.
We are exploring the option of using our salmon in the system, but currently water temperatures are too high to support their development. Currently, we have a campaign to raise money for the purchase of a large chiller which would help us maintain our water temperatures at a lower level. The rainbow trout in our system produce waste that is supplied to plants in grow beds. The nitrates produced by the nitrogen cycle are taken up by the plants to support their growth. Currently, we are experimenting with plants and flowers including tomatoes, lettuce, lavender, thyme, lemon mint, sage, chives, morning glory, broccoli, kale, strawberries, turnips, melons, cucumbers, and radishes. The plants are growing in a soil-less clay pebble grow media or on rafts in the system. Not all fish and plants have survived. Our education process involves a large number of mistakes but through failure we are learning.
