Questions
- 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).
- Could plastic chips have been substituted for the washers?
(No. The chips would not be attracted to the vehicle's
magnet.)
- Describe your search pattern.
(Answers will vary, but most will use the grid lines
to orient straight paths through the search area.)
- What makes a search pattern effective?
(Accept all reasonable answers such as sticking to a
predetermined method for covering territory.)
