5th grade students are watching aquaponics in Ms.
Smith’s classroom. They planted lettuce
in peat pods in October and moved the seedlings to the aquaponics towers in
November. Most of the lettuce is
thriving, drawing water from the goldfish tank underneath. The plant water is fertilized by the fish
waste and is then filtered and cleaned as it runs through the wicking and pods
in the tower. A few plants have withered
and the water was adjusted, but most are growing. We have also discussed whether natural light
would be helpful in increasing growth since so far, the towers have received
light from indoor plant lights only. Students think it’s cool that we aren’t
using a lot of water, but just recycling the same water. Students are researching the benefits of
aquaponics in writing class and will be writing persuasive arguments for or against
this modern farming technique, which, if successful, holds promise for feeding
people in areas with small land and water resources.
