## Lesson Plan: Senior Secondary 1 - Clothing and Textile
### Topic: Textile Test: Burning
#### Objective:
- Understand the importance of textile testing.
- Learn the procedure for conducting a burning test on fabrics.
- Identify different types of fibers by observing their burning characteristics.
#### Duration: 60 minutes
### Materials Needed:
- A variety of fabric samples (cotton, silk, wool, polyester, nylon, etc.)
- Metal tongs
- Candle or lighter
- Fireproof container or metal tray
- Water spray bottle (for safety)
- Safety goggles and gloves for each student
- Notebook and pen for students
- Chart to record observations
### Pre-Class Preparations:
- Set up a demonstration area where the burning test can be conducted safely.
- Ensure that all safety equipment is available and in good condition.
- Cut fabric samples into small, manageable pieces for testing.
- Prepare an observation chart for students to fill in during the experiment.
### Lesson Breakdown:
#### Introduction (10 minutes)
1. **Greetings and Attendance:** Welcome students and take attendance.
2. **Introduction to Textile Testing:** Briefly discuss the importance of textile testing in the clothing and textile industry. Explain that different tests help determine the properties and quality of fabrics.
3. **Introduction to the Burning Test:** Explain what the burning test is and its purpose in identifying different types of fibers based on their burning characteristics (e.g., smell, residue, flame color).
#### Demonstration & Explanation (15 minutes)
1. **Safety First:** Emphasize the importance of safety during the test. Ensure all students wear safety goggles and gloves.
2. **Demonstrating the Burning Test:**
- Show students each type of fabric sample.
- Using metal tongs, hold a sample over the candle or lighter flame until it starts to burn.
- Observe and describe the burning behavior: how it catches fire, the smell, the color of the flame, and the residue left behind.
3. **Recording Observations:** Fill in an example observation chart as a class.
#### Student Activity (25 minutes)
1. **Group Activity:**
- Divide students into small groups.
- Distribute fabric samples and safety equipment to each group.
- Instruct students to perform the burning test on each fabric sample, using the tongs and flame.
- Have each group record their observations in their notebooks and on the provided chart.
2. **Roaming the Room:** Teacher moves around the classroom, ensuring safe practices and answering any questions students may have.
#### Class Discussion (10 minutes)
1. **Group Presentations:** Each group presents their findings to the class.
2. **Comparing Observations:** Compare the recorded observations between groups and discuss any similarities or differences.
3. **Q&A:** Address any questions or concerns raised by the students.
#### Conclusion (5 minutes)
1. **Review:** Summarize the key points of the burning test and the importance of being able to identify fabric types.
2. **Homework Assignment:** Ask students to write a short report detailing the burning test procedure and their observations.
3. **Closing Remarks:** Thank students for their participation and remind them about safety practices even when they are not in the classroom.
### Assessment:
- Observation of student participation and adherence to safety practices during the activity.
- Evaluation of each group's observation chart.
- Review of homework reports for understanding and accuracy.
#### Additional Notes:
- Ensure all burning materials are extinguished properly and the area is cleaned up after the experiment.
- Students should understand the ethical implications of textile use and testing, such as considering the environmental impact of different types of fibers.
