Classroom Activity Page: Hydraulic fracturing, or fracking, is a high-pressure technique for cracking rocks and allowing natural gas to reach wells.

Opponents warn that the drilling-and-fracking process threatens to pollute air, surface water, and most importantly, groundwater. Will these concerns stymie an ongoing boom in natural gas production? Should they?
A high-pressure rock-buster caused natural gas production to explode. How does fracking work? What’s up with groundwater pollution?
