  1. Why was it important to camouflage the iron washers?
    (Since the activity explored the use of a search pattern, you needed to make sure that the car operator didn't see the targets and drive straight to them).
  2. Could plastic chips have been substituted for the washers?
    (No. The chips would not be attracted to the vehicle's magnet.)
  3. Describe your search pattern.
    (Answers will vary, but most will use the grid lines to orient straight paths through the search area.)
  4. What makes a search pattern effective?
    (Accept all reasonable answers such as sticking to a predetermined method for covering territory.)
