Teacher Dr Simon McMillan said the farm was established in 2014 with Ministry of Education funding, and later received funding from the Otago Community Trust.
From a "blank canvas" field of grass, an outdoor learning space has been developed.
It began with a focus on applied learning, science and sustainability.
"And from there, it became even more cross curricular, so I’m very pleased with that," Dr McMillan said.
Pupils could learn te reo Maori while identifying plants and animals, art pupils participated in outdoor drawing classes, and mathematics pupils used measuring skills while building a barn.
All the projects were created with teacher mentors helping pupils make it happen.
Projects on the farm included planting an apple orchard, establishing a chicken coop, building a berry house and introducing a small flock of sheep.
As well as providing learning experiences for college pupils, the farm had also welcomed pupils from local primary schools.
Pupil Zara Evans said a recent activity at the farm was trying to make fire using wood and kinetic energy.
The pupils had been able to revisit the farm over time to see the progress of planting various seeds, including vegetables and flowers.
Dr McMillan said an open day this Saturday was an opportunity to see how the farm could be used by other groups.
"I think we are still a bit of a secret in the valley."
