Lesson Plan: PLTW-PBS 1.1.1 - Introduction to the Science of Biometrics

Grade Level: 10

Duration: 30 minutes

Objectives

By the end of this lesson, students will be able to:

• Define biometrics and its applications in various fields.
• Identify different types of biometric systems.
• Understand the basic principles of how biometric systems work.

Materials Needed

• Projector and screen
• Computer with internet access
• Whiteboard and markers
• Biometric system samples (fingerprint scanner, facial recognition system)
• Worksheets for note-taking

Standards Alignment

This lesson aligns with the Next Generation Science Standards (NGSS), focusing on the interdependence of science, technology, and society.

Procedure

Introduction (5 minutes)

1. Engage the Class:

   • Begin the lesson by asking students if they have ever used a fingerprint scanner on their phones or facial recognition to unlock a device.
   • Prompt a brief discussion on personal experiences with biometrics.

2. State the Objective:

   • Inform students that today they will learn about biometrics and explore its applications in various fields, including security, healthcare, and forensics.

Direct Instruction (10 minutes)

1. Definition of Biometrics:

   • Introduce the term "biometrics." Explain that it refers to the measurement and statistical analysis of people’s unique physical and behavioral characteristics.

2. Types of Biometric Systems:

   • Discuss different categories of biometric systems including:
     • Physiological Biometrics: Fingerprints, facial recognition, iris scans.
     • Behavioral Biometrics: Voice recognition, keystroke dynamics.
   • Show examples of these systems using images or videos.

3. How Biometric Systems Work:

   • Explain the basic process of biometric recognition:
     • Enrollment: Capturing and storing a biometric sample.
     • Verification: Comparing a live sample to the enrolled biometric data.
     • Identification: Matching a live sample against a database.

Class Activity (10 minutes)

1. Group Discussion:

   • Divide the class into small groups. Assign each group a type of biometric system to research briefly.
   • Each group will answer the following questions:
     • How does this system work?
     • What are its advantages and disadvantages?
     • Where is it commonly used?

2. Share Findings:

   • After researching, have each group present their findings to the class. Allow approximately 1-2 minutes per group.

Conclusion (5 minutes)

1. Review Key Concepts:

   • Summarize the key points discussed in the lesson.
   • Reinforce the definition, types, and functions of biometrics.

2. Exit Ticket:

   • Ask students to write down one application of biometrics and one question they still have about the topic.

Assessment

• Formative assessment through class discussions and group presentations.
• Exit ticket to assess individual understanding and lingering questions.

Reflection

• After the lesson, consider how engaged students were during discussions and group work.
• Reflect on whether the objectives were met and what adjustments could improve future lessons on biometrics.

Extensions

• For students interested in further exploration, suggest researching advancements in biometric technology and its ethical implications in society.

By following this lesson plan, students will gain a foundational understanding of biometrics, preparing them for more complex discussions on the applications and implications of this technology in future science classes.
