Lesson Plan for Junior Secondary 1 - Basic Tech - Identification Of Ceramics & Glasses

**Lesson Plan: Identification of Ceramics & Glasses** **Class Level:** Junior Secondary 1 **Subject:** Basic Technology **Topic:** Identification of Ceramics & Glasses **Duration:** 60 minutes --- ### **Objectives** By the end of this lesson, students will be able to: 1. Define ceramics and glasses. 2. Identify the characteristics and uses of ceramics. 3. Identify the characteristics and uses of glasses. 4. Differentiate between ceramics and glasses. ### **Materials Needed** - Samples of various types of ceramics (tiles, pottery, porcelain) - Samples of glass (window glass, bottle, glassware) - Whiteboard and markers - PowerPoint presentation or printed visuals - Handouts with key points - Magnifying glasses (if available) --- ### **Lesson Structure** **Introduction (10 minutes)** 1. **Greeting and Attendance (2 minutes)** - Teacher greets the students and takes attendance. 2. **Starter Activity (3 minutes)** - Show students a ceramic mug and a glass cup. - Ask the class: "What do you think these are made of?" 3. **Lesson Objectives (2 minutes)** - Briefly introduce the lesson objectives to the students. 4. **Hook (3 minutes)** - Share an interesting fact about the history and use of ceramics and glasses, like how ancient civilizations used ceramics for art and glass for trading. **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. --- **Teacher's Notes** - Ensure all activities are inclusive and accessible to every student. - Adjust the lesson plan based on the actual class dynamics and available resources. - Be prepared to provide additional support for students who may have difficulty understanding the material. --- This structured, interactive lesson plan aims to make the topic engaging and informative for Junior Secondary 1 students.
