Scissors. Purple glue sticks. Paper designs to cut out and fold. Chris Lowry teaches advanced geology college courses at UB. But some of the tools he brings to class evoke the joy of grade school. Lowry is creator of the Foldable Aquifer Project — a series of 3D paper models of aquifers, which (in real life) consist of layers of permeable rock, sand and gravel that hold water underground.
