During our Quarter 2 PBL Unit on Rocks and Soil, the students learned about the attributes of rocks and soils, rock and soil types, the layers of soil and how rocks are formed, just to name a few things. The students were charged with creating a pet rock. They used what they learned about narrative writing to write their own Pet Rock story, answering the question, "If rocks and soil could talk, what stories would they tell?"
