The video tutorial guides students through a watershed lab, demonstrating how water flows through different terrains and how pollution can affect waterways. Using a crumpled paper model, the instructor marks high points, pollution sources, and waterways with different colored markers. The lab simulates rain to observe how water and pollutants move, highlighting the role of forests in mitigating pollution. Students are encouraged to replicate the lab at home and answer reflection questions based on their observations.
