**Teaching Content (20 minutes)**
1. **Definition and Introduction (5 minutes)**
- Define ceramics and glasses.
- Explain that ceramics are non-metallic, inorganic materials, typically made by shaping and then firing a non-metal mineral such as clay at a high temperature.
- Glass is an amorphous (non-crystalline) solid material commonly made from silica.
2. **Characteristics and Uses of Ceramics (7 minutes)**
- Discuss the characteristics: hard, brittle, resistant to high temperatures and chemicals.
- Show different ceramic items and explain their uses (tiles in bathrooms, insulators in electrical gadgets, pottery for storage and decoration).
3. **Characteristics and Uses of Glasses (7 minutes)**
- Illustrate the characteristics: transparent, brittle, can be molded when hot, impermeable.
- Show examples of glass items and explain their uses (windows, bottles, eyewear).
4. **Comparison (3 minutes)**
- List and explain the key differences between ceramics and glasses.
**Activity (20 minutes)**
1. **Hands-on Activity (10 minutes)**
- Divide students into small groups.
- Provide each group with samples of ceramics and glass.
- Give each group a magnifying glass (if available).
- Ask them to observe, touch, and discuss the characteristics of each sample.
2. **Group Presentation (7 minutes)**
- Each group presents their findings to the class.
- Encourage each group to name the item, state whether it is ceramic or glass, and describe its characteristics and potential use.
3. **Class Discussion (3 minutes)**
- Summarize the key points from the group presentations.
- Clarify any misconceptions and reinforce learning objectives.
**Conclusion (10 minutes)**
1. **Recap (5 minutes)**
- Recap the major points: definition, characteristics, uses, and differences between ceramics and glasses.
2. **Q&A Session (3 minutes)**
- Open the floor for any questions from the students.
3. **Closing Activity (2 minutes)**
- Give each student a handout summarizing the day's lesson.
- End the class with a quick quiz or fun fact.
**Evaluation**
- Assess students based on their participation in group activities and discussion.
- Collect and review the group presentations for understanding and accuracy.
### **Homework**
Ask students to bring one ceramic item and one glass item from home for the next class to create a small classroom display. Their homework is to write a brief description of each item, including its characteristics and use.
