By looking into the refractometer, students can measure how much salt added to the surface reached the aquifer below. ©Janet Krenn/VASG

A drop of water from the well sample is placed on a refractometer, which can measure salt in water. ©Janet Krenn/VASG

A water sample gets drawn up through a well, which is actually a straw that reaches all the way to the bottom of the cylinder. ©Janet Krenn/VASG

With the aquifer model complete, students add salty water to simulate pollution that gets added from runoff. ©Janet Krenn/VASG

The top layers of each model are customized to represent one of three types of landuse: urban, agriculture, and wetlands, shown here. ©Janet Krenn/VASG

Layers of rock, sand, and other materials are added to build the aquifer layer by layer. ©Janet Krenn/VASG

Chanel Graves (Craddock Middle School) pours in pea gravel to build her aquifer. She'll also add some water that will be ground water in the model. ©Janet Krenn/VASG
