At Lexington’s Providence Montessori Middle School, the students get their hands dirty. They have a lot to take care of outside the school.
There are several composting piles, a garden, several beehives, and some egg-laying chickens. Next to the garden, the students oversee a hoop house that has more garden plants and two tanks with fish, part of an aquaponics system.
The waste from the fish is collected in a settling chamber, and the students use it to fertilize plants without much soil called hydroponics.
