This document provides instructions for designing an eco-friendly tree house. Students will view a TED Talk on bio-mimicry and symbiotic design inspired by nature. They will then look at examples of innovative tree house designs for inspiration. Students will outline what materials and environment their tree house will use, and describe how it will mimic a nature element to survive without pollution. Their design should consider recycling waste and using green energy sources like water, wind or solar power. They will sketch their tree house design and label any efficient features.
