WV State Standards: Science: SC.9.1.1, SC.9.1.3, SC.9.1.4, SC.9.5.1, SC.9.5.2 Math: AGP.5.1 National Standards:  Science: Nature of Science  11, 12, 13 Blooms Taxonomy: Knowledge Comprehension, Evaluation, Synthesis  21st Century Skills: Communication skills, information and media literacy skills, self-direction, interpersonal and collaborative skills

Objective(s)

Students will:

• examine how minutiae points are extracted from fingerprints to create a stored template
• plot and record the x and y coordinates for each minutiae point
• plot and record the angle for each minutiae point
• analyze activity to respond to journal questions

Time Required

2 - 45 minute class period

Pre-Requisite Skills

Basic internet navigation, basic co-ordinate graphing skills

21st Century Tools (Technology Tools)

Internet Access

Instructional Materials

Minutia Marked Fingerprint
Cartesian Graph Overhead Transparency Sheet
Polar Graph Overhead Transparency Sheet
Overhead markers, paper clips
Student Laboratory Instruction Sheet
Sample Data Table

Procedure

1. Distribute Student Laboratory Instruction Sheet
2. Place the Cartesian Graph Overhead Transparency Sheet onto the minutiae marked fingerprint.
3. Paperclip on to prevent movement of the transparency.
4. Using an overhead marker, mark all minutiae points, by placing dots on the Cartesian grid.
5. Remove transparency.
6. Record the x and y coordinates for each minutiae point
7. Repeat steps 1 through 4 using Polar Graph Overhead Transparency Sheet .
8. Record the polar angle location of for each minutiae point.
9. Using Microsoft Excel, Organize all information about each minutiae point into an organized data table. (If you have no access to Excel use traditional data table)
10. Students are to write a lab summary report detailing the activity, including procedures, results, and conclusions.
11. Students will respond the following journal questions after viewing presentation:

• Discuss types of experimental errors that could have occurred during your collection of data.
• Discuss advantages and disadvantages to using minutiae templates for fingerprint identification purposes.

Differentiated Instruction

Modifications should occur according to the school's inclusion plan and the individual student's IEP
Journal Questions can be modified to meet individual needs of each student or course.
Handouts for power point may be made for individual students.

Collaboration

Activity may be integrated into math courses to reinforce basic graphing skills.

Author's Comments

When making the overhead transparencies using a colored grid allows for more visibility in marking of minutiae points. A blog may be created using www.blogspot.com to allow students to blog journal answers.

21st Century Assessment/Evaluation

Oral discussion about the accuracy of the lab activity. Evaluation of laboratory report summary. (evaluation rubric)
