from branches to bridges This was our first unit of urban planning. We looked closely at SDG 11 as we built our bridge. SDG 11 is to make cities and human settlements inclusive, safe, resilient and sustainable. With SDG 11 we got to explore how to make a strong bridge. Our teacher took us around down town and allowed us to explore the different architecture and the art of the city. I had to cut the wood in weird angles. I over all had a lot of fun.
