**Lesson Structure:**
**1. Introduction (15 minutes):**
a. Greeting and attendance.
b. Brief overview of today’s topics: Coal and Fuel Gases.
c. Learning objectives outline.
d. Starter Question: "What do you already know about coal and its uses?"
**2. Explanation/Direct Instruction (30 minutes):**
a. **Coal:**
- Definition and types (Anthracite, Bituminous, Sub-bituminous, Lignite).
- Formation process (carbonization of wood over millions of years).
- Diagramming the coal formation process on the board or using PowerPoint.
b. **Uses of Coal:**
- Primary source of energy for electricity generation.
- Industrial uses: steel production, manufacturing of cement, etc.
c. **Fuel Gases:**
- Definitions and examples (natural gas, coal gas, water gas, producer gas).
- Production processes.
- Composition and uses of each type of fuel gas.
**3. Demonstration (20 minutes):**
a. Demonstration of Coal Gasification:
- Setting up lab equipment (Ensure all students wear safety equipment).
- Step-by-step process to show the production of gas from coal.
- Collecting and observing the gas produced.
b. Discussion of observations and linking them to theoretical concepts.
**4. Guided Practice (10 minutes):**
a. Divide students into small groups.
b. Provide each group with handouts, which include diagrams and questions on coal formation and fuel gas production.
c. Groups should discuss and fill out their handouts collaboratively.
**5. Group Activity (10 minutes):**
a. Each group presents their answers and discusses with the class.
b. Encourage critical thinking: "What are the pros and cons of using coal and fuel gases as energy sources?"
**6. Assessment (5 minutes):**
a. Quick quiz with multiple-choice and short answer questions on:
- Types of coal.
- Uses of coal.
- Different fuel gases and their compositions.
b. Collect quiz results for evaluation.
**7. Conclusion (5 minutes):**
a. Recap key points discussed.
b. Open floor for any final questions or clarifications.
c. Assign homework: Research and write a short essay on "Environmental impacts of coal mining and fuel gas production."

**Homework/Extension Activities:**
1. Research local sources of coal and fuel gases; prepare a short presentation.
2. Study advancements in clean coal technology and alternative fuel sources.
**Assessment/Evaluation:**
- Evaluate student participation in discussions and activities.
- Quiz performance.
- Completion and quality of homework assignments.
**Safety Considerations:**
Ensure all lab safety protocols are followed:
- Students must wear safety goggles and gloves during the lab demonstration.
- Proper handling of the Bunsen burner and other lab equipment.
- Supervision during the practical activities.
**Differentiation:**
- Provide additional resources or simplified explanations for students who need extra support.
- Challenge advanced students with more complex questions and research topics.
