1. Begin the lesson by having each student fingerprint themselves. Each student should do his or her index finger on one of the 3x5 cards. Then, using the examples found on the Zoom website, below, find out what percent of the class members have whorls, loops, or arches in their fingerprints.
2. Next, divide the class into four groups, assigning each group the task of researching the following:
- Group 1: The History of Fingerprinting
- Group 2: Problems with Fingerprinting
- Group 3: The Development of DNA Evidence
- Group 4: Problems with DNA Evidence
3. Each group should select a means of sharing its findings with the rest of the class. This might be an oral report with handouts, a PowerPoint presentation, or some other means. Set aside one day for such presentations.
4. Conclude the lesson with a discussion of the class’s findings, and consideration of ethical issues involving our ability to identify people in these ways. What are the implications of these technologies for privacy? For misuse? Is it the case that if one has nothing to hide, one shouldn’t object to having ones fingerprints or DNA on file somewhere?
