End of Chapter Activities
Below you will find case studies and case file activities students may complete at the end of the chapter. I have included the "Scenario" statements provided in the student textbook for each activity. For cases that do not list a "Scenario" or for scenarios that are extensive, I have provided a description of objectives instead. These "Case Files" will be used to guide each chapter.
Students will engage in many other activities provided by the textbook resource and they will access all activities through the Schoology platform.

Casting Impressions of Hammer Strikes on Wood in Silicone
Casting Impressions of Hammer Strikes on Wood in Silicone
Police received a report of a construction site break-in. The specifics of the case suggested that it was an “inside job,” involving one of the site’s employees. The break-in involved a locked wooden toolbox that had clearly been broken with a hammer. The toolbox contained cash. No hammer was found at the site of the break-in, and it was assumed that the thief used a personal hammer. Police collected all of the workers’ hammers for testing. Your task is to produce casts of the hammer strikes for comparison to the tool mark evidence found at the crime scene.
