In Podcast #32 Frank, Alfonso, and David take you to the Luckstone Rock Quarry in Richmond, Virginia, right along the James River.  Brad couldn’t be with us for this video, but we added him on with the magic of technology!  Find out how rocks are blasted out of the ground and crushed into tiny bits with huge powerful machines.  Discover how the rocks from this quarry are used and reused all over Virginia... even right under your feet!   See how the rock cycle and the water cycle both play important parts at Luckstone Quarry.   Learn which elements and compounds make explosions, super hard metals, and fools gold!   Come on, let's go trekkin'!

Each person uses about 14 tons of rock a year. How?  Rocks, stone, and gravel (also called aggregate) are used to make buildings, roads, and sidewalks, provide bedding for underground pipes and cables, purify water for drinking, prevent erosion, and even make common products like glass, toothpaste, paint, and paper.  (Source) To build an average school requires 13,000 tons of aggregate!
