The Fracking MEL
Below are links to resources that will help students use the Fracking MEL and learn more about fundamental scientific principles related to this issue.
This article provides an introduction to the Fracking MEL plus suggestions from classroom use including management tips and specific areas in which students might have difficulties and suggestions for assisting students with their understanding, such as providing additional background information and hands-on investigations.Evaluating the Connections Between Fracking and Earthquakes TES (Acrobat (PDF) 1019kB Jun4 18)
Model A: The increase in moderate magnitude earthquakes in the Midwest is caused by fracking for fossil fuels.
Model B: The increase in moderate magnitude earthquakes in the Midwest is caused by normal tectonic plate motion.

Lines of Evidence
Evidence #1: Fracking fluids and wastewater injected into the ground change the stress in Earth's crust.
Evidence #2: During recent years, the number of earthquakes near fracking sites was 11 times higher than the 30-year average.
Evidence #3: Convection of hot but solid and ductile rocks in the upper mantle creates stresses in Earth's crust. These stresses cause Earth's crust to fracture.
Evidence #4: Many earthquakes are currently occurring in regions surrounding fracking sites.

When the Fracking MEL was first introduced to the students, it was became clear that the geologic processes involved in fracking were unfamiliar to most. This introductory background reading was developed to assist students.

This Plausibility Ranking Task (PRT), which may be completed prior to using any MELs, helps students to understand the role of evidence in supporting or refuting models.

The Explanation Task is part of each MEL Activity. In this task, students provide written explanations for the arrows they draw on the diagram. The following rubric may be used to score students' written explanations.
