Chang takes us through the lines of banyans, royal palms, birches, and cedars near the school walls to an environmental observation platform and wading path made of earth, wood, and stone set in the ground. Gazing out, we see a rice field, the ecological pool, and four composting bins.
穿過圍牆旁邊大榕樹、大王椰子、樺樹、杉樹等組成的樹陣，張啟明帶我們走上由泥土、木材及碎石鋪成的生態觀察平台及涉水步道，放眼望去，依序是水稻田、生態池，以及由 4 個槽櫃組成的「落葉堆肥區」。
