Two fun tool mark impression activities for your forensics class! One activity is digital and NO PREP, the other is hands on. Both will challenge your students to practice their tool mark analysis skills.
1) Digital Activity
This is student-independent, just share it and let them work! Students move through 11 interactive Google Slides. They collect and compare tool marks from the crime scene and suspect tools to find a match. The resource includes a detailed Key for easy grading. It takes my 10th graders around 15 minutes to complete the assignment.
2) Hands On Activity
There are two versions of the hands on activity, depending on how much time you want to spend. The Detailed Analysis activity asks students to make test marks and of various tools, measure the mark and record observations on the provided student sheet. The activity can take up to an hour to complete, depending on how many sets of tools the students are given.
The Quick Activity has the same simple set up, but does not require detailed record keeping on their student sheet. It could take as little as 15 minutes, depending on the number of tools.
Both hands on activity sheets include an example to guide student responses – they will know exactly what you expect them to do!
Additional materials you will need for the hands on activity:
Modeling Clay or Playdoh
Sets of tools – three of each type. I ask my students to bring some in, or find them at yard sales.
