The height of the tallest building in your neighbourhood. What did you use as a reference to estimate the height?

Correct Answer

Method: Students estimate the height by comparing with known reference points.

Reference Points:

  • Single-storeyed house: approximately 3-4 m
  • Electric pole: approximately 8-10 m
  • Floor count method: Count the number of floors and multiply by 3-4 m per floor

Note: The chapter encourages students to use estimation skills by comparing unknown heights with known reference points. Students can count floors and multiply, or compare with nearby structures of known height.
