### Lesson Plan: Materials and Their Common Uses
**Subject:** Basic Tech
**Grade:** Junior Secondary 2
**Duration:** 60 minutes
#### Objectives:
- Students should be able to identify and classify various materials.
- Students should understand the common uses of different materials.
- Students should develop an appreciation for the selection and use of materials in everyday objects.
#### Materials Needed:
- Samples of different materials (plastic, metal, wood, glass, fabric, etc.)
- Projector or smartboard
- Presentation slides
- Handout with key points (optional)
- Worksheet for group activity
- Markers and chart paper
- Any common household items (optional for practical demonstration)
#### Lesson Structure:
**Introduction (10 minutes):**
1. **Greeting and Attendance (2 minutes):**
- Take attendance and greet students warmly.
2. **Warm-up Activity (8 minutes):**
- Show pictures of common objects (chair, bottle, window, sweater, etc.) on the projector.
- Prompt students to guess the materials used to make these objects through a quick discussion.
- This helps in grabbing their attention and setting the context for the lesson.
**Instructional Input (20 minutes):**
1. **Explain Different Types of Materials (10 minutes):**
- Present a short slide deck or use the smartboard to introduce different types of materials: Metals, Plastics, Wood, Glass, Fabrics, etc.
- Use samples to show and pass around to students for a tactile experience.
- Briefly explain the characteristics of each material (e.g., metals are strong and durable, plastics are lightweight and versatile).
2. **Common Uses of Materials (10 minutes):**
- Link the materials to their common uses.
- Discuss why certain materials are chosen for specific purposes (e.g., glass for windows because it’s transparent, wood for furniture because it’s sturdy and easy to shape).
- Use real-world examples and pictures to illustrate the points.
**Guided Practice (15 minutes):**
1. **Group Activity (15 minutes):**
- Divide the class into small groups.
- Provide each group with a worksheet listing various objects.
- Ask groups to identify the materials used and explain why those materials are suitable for making the objects.
- Optional: Provide physical objects for more hands-on identification if available.
**Independent Practice (10 minutes):**
1. **Worksheet Completion (10 minutes):**
- Distribute individual worksheets with additional questions about materials and their uses.
- Students complete the worksheets independently.
- Walk around and provide guidance where needed.
**Closing (5 minutes):**
1. **Review Key Points (3 minutes):**
- Quickly review the types of materials and their common uses.
- Answer any lingering questions from students.
2. **Assignment and Wrap-Up (2 minutes):**
- Assign a homework task where students find and list 10 different items at home, identify their materials, and explain why those materials are used (due next class).
- Thank students for their participation and attention.
#### Assessment:
- Collect and assess the group activity worksheets.
- Review and provide feedback on the homework assignment.
- Evaluate students’ understanding through participation and responses during the lesson.
#### Extension:
- Explore the environmental impact of using different materials.
- Discuss recycling and sustainable use of materials in future lessons.
