In this 5E Model Explore-Explain activity sequence, students will explore the structure of aquifers. First, they will investigate porosity and permeability to understand how Earth’s sediments affect the availability of groundwater - its ability to be stored, flow, and be accessed by humans. Then, they will use data from well logs to create a visual model of the structure of an aquifer, drawing conclusions about the flow of groundwater in the aquifer, the impacts of land use, and the overall qual
