**Lesson Plan: Properties of Materials**
---
**Grade Level:** Year 6
**Subject:** Science
**Duration:** 1 hour
**Topic:** Properties of Materials
---
### Objectives:
1. Students will identify different materials and their properties.
2. Students will categorize materials based on their physical properties such as hardness, flexibility, transparency, and conductivity.
3. Students will understand the practical applications of different materials based on their properties.
### Materials Needed:
- Various sample materials (metal, wood, plastic, glass, fabric, rubber, etc.)
- Magnifying glasses
- Worksheets for data recording
- Whiteboard and markers
- Projector and computer (for videos)
- Containers of water
- Scissors and rulers
### Lesson Outline:
#### Introduction (10 minutes)
1. **Greeting and Attendance:**
- Welcome students.
- Take attendance.
2. **Hook:**
- Show a short video introduction about the different materials and their properties. (3-5 minutes)
3. **Objective Overview:**
- Briefly explain the objectives of the lesson.
#### Direct Instruction (15 minutes)
1. **Explanation of Key Concepts:**
- Define 'material' and 'properties of materials'. Use the whiteboard to write down key terms and definitions.
- **Material**: Any substance that is used to make things.
- **Properties**: Characteristics that define and describe materials.
- Discuss various properties such as hardness, flexibility, transparency, and conductivity.
2. **Examples:**
- Provide real-world examples of where different materials are used and why. For example, glass for windows because of its transparency, metal for wires because of its conductivity.
#### Hands-on Activity (25 minutes)
1. **Group Work:**
- Divide students into small groups (4-5 students per group).
- Provide each group with a set of different material samples.
2. **Investigation and Recording:**
- Have each group examine the materials using magnifying glasses and other tools.
- Students should test the materials for different properties:
- Hardness: Can they scratch it?
- Flexibility: Can they bend it without breaking?
- Transparency: Can they see through it?
- Conductivity: Discuss and hypothesize about which materials might conduct electricity.
3. **Worksheet Completion:**
- Provide worksheets for data recording. Each group should fill out their observations about each material sample.
#### Discussion and Reflection (10 minutes)
1. **Group Presentations:**
- Allow each group to briefly present their findings to the class.
- Discuss the results together, reinforcing key points.
2. **Q&A Session:**
- Open the floor for students to ask questions and express what they learned.
- Address any misconceptions.
#### Conclusion (5 minutes)
1. **Summary:**
- Recap the main points of the lesson, emphasizing the properties and their importance in practical applications.
2. **Homework Assignment:**
- Assign students to find an object at home, identify the materials it's made of, and describe the properties that make those materials suitable for that object. They should prepare a short paragraph to share in the next class.
### Assessment:
- **Formative Assessment:** Observe group discussions, participation during hands-on activity, and group presentations.
- **Summative Assessment:** Review the completed worksheets and homework assignments for understanding and correct application of concepts.

### Additional Notes:
- Ensure that all materials used are safe for children.
- Adjust the lesson pace based on the class’s understanding and engagement.
- Provide extra assistance to groups or individuals who need help with the concepts.
