Objective(s)

Students will identify and measure specific hand geometry measurements. Students will classify objects using a given system.

Time Required

45 minutes

Pre-Requisite Skills

Basic knowledge from lesson 1 on biometrics. Be familiar with using a cm ruler.

21st Century Tools (Technology Tools)

Scanner or copy machine

Instructional Materials

Metric ruler, 2 copies each of 6 various hands, Teacher Copy: Post at front of the room with measurements included.
Student Copy:  worksheet for measuring and matching

Procedure

1. Before lesson, teacher will scan at least 6 pictures of various (2 copies of each). Teacher will also measure and place measurements at the bottom of the hands. See Teacher Copy.
2. Teacher will review background information of hand geometry with class.
3. Teacher will post pictures of hands in the front of the room.  The hand will be covered, but the measurements will be disclosed. Label pictures as Suspect A, B, C, D, E or F.
4. Distribute to groups of 3 or 4 students Student Copy.  Students will then use rulers to measure to nearest millimeter various parts of the hand to develop a key.
5. Students will then compare their results with the measurements at the front of the room to identify their hand as Suspect A, B, C, D, E, or F.
6. When all groups are finished, ask group to share their findings.  Reveal the pictures of the hands to see if each group is correct.
7. Use following teacher discussion questions: Did your measurements match exactly? why or why not?  What are some advantages/disadvantages to for using hand geometry?  Where do you think hand geometry would best be used?

Differentiated Instruction

Grouping students into heterogenous groups will allow for students to be successful.

Collaboration

Students will work in collaborative groups to measure hand geometry. These lessons can be used across the curriculum in math and science.

Author's Comments

As an extension to this activity, students may create their own measuring system and share with the class.

21st Century Assessment/Evaluation

Teacher will assess students based on whether or not they measured correctly in order to match suspects to their hands. Teacher will also assesss answers to discussion questions.
