Product Description
A graphic simulation of the principles of groundwater movement and contamination. Using this durable acrylic model, students will learn about the sources of groundwater, its storage and flow beneath the earth's surface, and how this resource impacts life at the earth's surface. Dyes are used as simulated contaminants to reveal how groundwater can become polluted and affect drinking water supplies. By demonstrating concepts, students learn about groundwater's critical role in the hydrological cycle and other key concepts: groundwater pollution, porosity and permeability, Darcy's Law, aquifers and artesian wells, water quality, and the interrelationship of groundwater and surface water. Includes sand, gravel, clay, nontoxic dyes, connectors, tubing, syringe, pumps, pipets, an electric pump for the realistic simulation of continuous water recharging, permanently attached reservoir and easy-to-use student and teacher guides Size: 20" L x 5" W x 12-1/2" H. Grades 7-12.
