Aqua Garden

This is the perfect way to demonstrate to my fourth grade scientists how biotic factors and abiotic factors are interdependent in an ecosystem. The water and the wastes from the fish are pumped up to the plants and then the clean water is cycled back down to the fish. We are growing wheat grass and radish sprouts from organic seeds.
