Students measure the pH of soil samples from a hypothetical site to locate a contaminant spill and will predict the direction of groundwater flow using mathematical modeling. They use the engineering design process to develop...

Students examine urban runoff and identify peak flows. They examine causes for different flow rates, and complete worksheets and a graph.

Thirsty plants soak up every bit of a rainfall, but what happens to the rain that hits the roof? Calculate the amount of rainwater from your school's roof with an Earth science activity, which brings measurement skills, observation...

Discusses the mathematics involved in basic pumping well hydraulics. Includes a section dealing with the steady state solution.
