A school project model of a sustainable eco-friendly house made out of cardboard. The house has a slanted roof with solar panels, a small wind turbine beside it, a rainwater collection system with gutters leading to a water tank, a green roof with plants, large windows, and a small garden with recycling bins. The model looks handmade using cardboard, paper, straws, and craft materials. There are labels and arrows showing water and energy flow. Bright classroom setting, neat and realistic. See more
