This document provides an overview and training guide for River-Lab grade 4 online and outdoor training. It summarizes the River-Lab environmental education program, which uses a river basin curriculum across Fairfield schools. It outlines the grade 4 unit on the groundwater system and conducting study trips along the Mill River, led by trained volunteer guides.

104. Trail Point #6: Human Impact on River Basin Productivity At the “eroding bend” location, students will observe and discuss the ways humans have changed and developed the land. Analyze the absorbent and non-absorbent features of the area. What are the implications of resurfaced areas on the groundwater system? What are the consequences for habitats and the organisms that live there? Without sufficient absorbent features, runoff and flooding will cause erosion, and the groundwater system will not store enough water to replenish habitats. Experience the Concept on the Trail
