Grade: Date: 17/01/2026
Subject: Biology
Lesson Topic: Convert measurements between millimetres (mm) and micrometres (μm).
Learning Objective/s:
  • Describe the relationship between millimetres and micrometres.
  • Apply the conversion formulae to change measurements between mm and μm.
  • Solve real‑world biology problems using these conversions.
Materials Needed:
  • Projector or interactive whiteboard
  • Slide presentation with conversion tables
  • Worksheet with practice conversion problems
  • Rulers or digital scale‑bar images
  • Calculator (optional)
 Introduction:
Begin with a quick visual of a human hair and a virus to highlight the huge size range in biology. Review that students already know metric units and powers of ten. Explain that by the end of the lesson they will accurately convert between millimetres and micrometres and check their work using a conversion chart.
Lesson Structure:
  1. Do‑now (5') – Students answer two conversion questions on the board.
  2. Mini‑lecture (10') – Present the relationship 1 mm = 1000 μm and demonstrate the formulas.
  3. Guided practice (10') – Work through the three worked examples together, prompting student input.
  4. Independent practice (15') – Students complete the practice worksheet while the teacher circulates.
  5. Quick check (5') – Kahoot quiz or exit ticket with two conversion items to gauge understanding.
  6. Summary & reflection (5') – Review key steps and address any misconceptions.
Conclusion:
Recap that multiplying by 1000 converts mm to μm and dividing by 1000 does the reverse. For the exit ticket, ask each student to write one conversion they found challenging and how they solved it. Assign homework to complete a set of conversion problems from the textbook.
