Subject: Physics
Lesson Topic: Recall and use the equation average speed = total distance travelled / total time taken
Learning Objective/s:
  • Recall the definition of average speed and the formula vavg = D / t.
  • Identify distance (metres) and time (seconds) and convert units where necessary.
  • Apply the formula to calculate average speed for given situations.
  • Check that results are expressed in metres per second (m s⁻¹).
  • Solve contextual motion problems using average speed.
Materials Needed:
  • Whiteboard and markers
  • Projector or interactive display
  • Printed worksheet with examples and practice problems
  • Ruler or measuring tape for demonstration
  • Calculator (optional)
  • Diagram of a car travelling a distance D in time t (slide/handout)
 Introduction:
Begin with a quick real‑world question: “How fast did a car travel if it covered 120 m in 30 s?” Students recall that speed is distance divided by time and note that average speed is a scalar quantity. Review that distance is measured in metres and time in seconds. Explain that by the end of the lesson they will be able to use the equation vavg = D / t correctly and check their units.
Lesson Structure:
  1. Do‑now (5'): Students answer the opening question on the board and share their answer.
  2. Mini‑lecture (10'): Review key concepts (distance, time, units, formula) with a slide and the suggested diagram.
  3. Guided practice (12'): Walk through the step‑by‑step procedure using Example 1; students complete the same steps on their worksheet.
  4. Independent practice (15'): Students solve three practice problems, inserting values, performing the division, and checking units.
  5. Peer check (5'): Pairs exchange worksheets, verify each other's calculations and discuss any errors.
  6. Exit‑ticket quiz (8'): One short problem on average speed; collect for quick assessment.
Conclusion:
Recap that average speed is total distance divided by total time and that correct units are essential. Students reflect on the steps they used to solve the problems. Collect the exit tickets and assign a homework worksheet with additional motion scenarios to reinforce the concept.
