Students learn how to read topographic maps and delineate watershed boundaries, and locate their homes and school in the watershed. They follow the course of a raindrop from its point of impact on the watershed to the exit point as it flows into the ocean.
Students explore the food chain, including the driving forces of the sun, soil, water, and air.
They are given a pond guide and additional materials which show them the specific plants and animals that exist, where they may be found, and what they need to survive in wetland ecosystems. Students sample water for flora and fauna and describe the differences of their findings with respect to the source. They relate their field experiences with what they've learned iil the classroom. Experiments illustrate how an aquifer supplies water to wells and reservoirs. The session also emphasizes the interconnection between wetlands, groundwater, and surface water.
