I’ve recently finished my second windowfarm project with fourth grade elementary school children, and I’ve discovered an incredible new world. After seeing Britta Riley’s TED lecture, I figured I really should try and build an aquaponic windowfarm system with the children I teach.
The difference this time was that we’ve decided to go at it as a project based course (PBL). 14 meetings, 75 minutes each. We’ve started by planning the system together, acquiring the materials, building the system- including a wooden hanging rack, taking care of the plants, the fish, and the pumps. After the system was set up we’ve started following the plants’ growth. We’ve had 2 columns running to a fish aquarium with 5 goldfish, and one column with a bucket with water and fertilizer. Each column had different types of plants to compare their growth rate. The children were in charge of everything – taking care of the windowfarm, following the farm as it evolves (plants & fish), documenting the process, and finally presenting all they did to their parents over a glass of farm-grown mint tea .
It was an incredible success.
I’d love to share with you some of the insights
