Questions

  1. If each chalked gird box represents a two-foot by two-foot square, how long is the submarine?
    (40 feet)
  2. How could you create a larger drawing of the submarine, but still retain its scale dimensions?
    (Create the chalk grid with a greater distance between the lines)
  3. How might increasing the number of lines in the scaled down grid affect the accuracy of the final drawing?
    (With additional reference lines, the copying process might be more accurate)

The activities in this guide were contributed by Michael DiSpezio, a Massachusetts-based science writer and author of "Critical Thinking Puzzles" and "Awesome Experiments in Light & Sound" (Sterling Publishing Co., NY).
