Acid, Acid Everywhere
"Students will be able to analyze several systems during the course of the unit. These include the "problem system", defined by the boundaries of the area affected by the acid spill; the stream ecosystem (into which the acid flows); and the transportation system (which will be disrupted by the acid spill). In addition, all experiments set up during the course will be treated as systems."--P. 3.
