Groundwater makes up a significant portion of Earth`s fresh water. Students will learn what groundwater is, how it moves through the subsurface, and how porosity and permeability affect its movement. The impact of environmental issues on certain areas will also be studied through this lens. As a hands-on activity, students will study water`s movement through three different substrates, measuring the porosity and permeability of each, then comparing the three. This kit includes enough material for 15 groups of students, and includes teacher`s manual, student study guide copymasters, and safety data sheets. Additional items needed: 50mL graduated cylinders, markers, and stopwatches.
