Collecting Soil

Today after school, Tiffany and I went to Tsinghua University to collect soil for environmental science lab tomorrow. We first got two shovels from the classroom, one is small like the one you use to plant, the other was huge like one you would use to hide treasure box. On the way, I found it weird but fun to carry a huge shovel waking on street. It seemed like I was going to discover a treasure or hide something nasty like what usually happens in CSI or Criminal Mind. We collected two whole bag of soil, one from nearby a lake, the other from area in front of the library. I hope to discovery some species in those soil in later lab. :)
