Based on your students’ knowledge of chemistry, local police have asked for their help in solving a local missing-persons case. The victim in this case is Kirsten K. Your students will try to determine which of the suspects is most likely responsible for her disappearance based on the evidence provided by the police and analyzed by the students.

In the first part of this performance assessment, your students will analyze samples from a recycling plant to determine where police should begin their search for the victim. In the second part, your students will analyze data from an airbag deployment to determine whether the delivery truck driven by the victim prior to her disappearance can be extracted from the lake so that further evidence can be recovered.

This sample chapter also includes the Table of Contents and Index.
