Smart Greenhouse

School Overview

South Hobart Primary School is located in South Hobart, Tasmania and caters for students in years K – 6 from the surrounding community. South Hobart Primary School currently has 378 students.

Problem / Challenge

How can we grow food all year around in Tasmania without using more energy than transporting it?


In different engineering teams, each team is addressing the problem from a particular perspective.

  • Software/electronic engineering are responsible for sensors: – watering systems, temperature controls, nutrient levels.
  • Environmental engineering for soil, planting: choice, numbers, density, companion and pest control.
  • Civil engineering for design, scale drawings, costing and construction.

Then, as a whole group they come up with the ‘perfect greenhouse’ by putting all the ideas together.
