Product Description
This performance assessment on introductory acid/base chemistry uses a scenario where high school students assist in determining water pollution by acids and bases. Individual students perform pH testing of samples.
The student goal is twofold:
1. Determine which sample came from which collection point.
2. Defend their decision as to whether three factories are polluting the Casediba River.
Options are provided for both wet-lab and dry-lab procedures. The wet-lab procedures also provide choice between directed and self-generated procedures.
Teacher notes include answers to questions, preparation hints, and detailed instructions for conducting the assessment that includes “placemats” for setting up sample testing stations.
