This document discusses the need to view the environment as a natural laboratory for teaching science and mathematics. It argues that many concepts are taught only theoretically in classrooms, when in fact they are all around us in our daily environment and experiences. Some examples given include teaching about pressure by having students step on different surfaces, teaching about liquids by comparing water bottles of different sizes, and teaching about moments by observing everyday actions like opening doors. The author argues that if teachers looked more closely at the environment, they would find opportunities to teach practically every lesson without needing a specialized laboratory. Students would better understand concepts that are part of their everyday lives. Overall, the document advocates using the natural environment more actively as a hands-on "laboratory"
