Subject: Chemistry
Lesson Topic: State that hydrocarbons are compounds that contain hydrogen and carbon only
Learning Objective/s:
  • Describe the definition of hydrocarbons and identify that they contain only carbon and hydrogen.
  • Explain the three main types of hydrocarbons (alkanes, alkenes, alkynes) and their general formulas.
  • Identify the primary hydrocarbon components of common fuels such as natural gas, petrol, diesel, LPG, and coal.
  • Interpret the combustion equation for hydrocarbons and relate it to energy release.
  • Apply knowledge by classifying a given fuel based on its hydrocarbon composition.
Materials Needed:
  • Projector or interactive whiteboard
  • Printed worksheet with hydrocarbon formulas
  • Molecular model kits (optional)
  • Sample fuel labels or images
  • Whiteboard and markers
  • Exit ticket cards
 Introduction:
Begin with a quick poll: “What fuels power the cars and stoves you use daily?” Connect this to students’ prior knowledge of carbon and hydrogen atoms, then outline that by the end of the lesson they will be able to state the definition of hydrocarbons, list their main types, and explain why they are useful as fuels.
Lesson Structure:
  1. Do‑now (5') – short quiz on element symbols C and H and basic formulas.
  2. Mini‑lecture (10') – definition of hydrocarbons, introduction to alkanes, alkenes, alkynes with slide visuals.
  3. Guided worksheet activity (15') – in pairs, match common fuels to their main hydrocarbon component using the provided table.
  4. Demonstration (10') – safe combustion of a methane‑burner model; discuss heat and light release.
  5. Check for understanding (5') – interactive Kahoot questions covering definitions and fuel examples.
  6. Summary & exit ticket (5') – students write one key fact learned and one lingering question on a card.
Conclusion:
Recap the definition of hydrocarbons, their three types, and how they power everyday fuels. Collect exit tickets to gauge understanding and assign a brief homework: research one fuel’s environmental impact and prepare a one‑minute summary for the next class.
