Lesson Topic: Name methane as the main constituent of natural gas
Learning Objective/s:
  • Describe the composition of natural gas and identify methane as its main constituent.
  • Explain the key physical and chemical properties of methane.
  • Compare methane with other common fuels in terms of energy content and environmental impact.
  • Discuss safety considerations when handling methane.
Materials Needed:
  • Projector and laptop for presentation
  • Whiteboard and markers
  • Printed worksheet with fuel comparison table
  • Molecular model kit (for CH4)
  • Safety data sheet for methane
  • Exit‑ticket slips
 Introduction:
Begin with a quick poll: which fuels students use at home. Connect responses to prior knowledge of solid, liquid, and gaseous fuels. State that by the end of the lesson they will be able to name methane as the main constituent of natural gas and explain why it dominates.
Lesson Structure:
  1. Do‑now (5'): List three everyday fuels on a sticky note.
  2. Mini‑lecture (10'): Introduce fuel categories and overview of natural gas.
  3. Guided inquiry (12'): Examine the fuel comparison table; highlight methane’s properties.
  4. Demonstration/model (8'): Build a methane molecule with the kit and write the balanced combustion equation.
  5. Think‑pair‑share (8'): Discuss why methane dominates natural gas; record reasons.
  6. Quick revision quiz (7'): Answer three questions from the source notes.
  7. Exit ticket (5'): Write the formula of methane and one safety precaution.
Conclusion:
Recap the main points: methane’s formula, key properties, and its advantages as a natural‑gas component. Collect exit tickets to check understanding, and assign homework to research another gaseous fuel and prepare a short paragraph summarising its main features.
