Challenge #12: Finding Your Way Home

Everyone has one of these now a days. In fact some people cannot leave home without it. I am talking about a GPS unit. Check out the picture in case you have never seen one before. We have been using one in the field for a couple of reasons. One of the reasons is to keep track of where we have parked the car and the other reason is so that we can assign a location to the surveys that we do of the caterpillars.

1. What does GPS stand for?

2. How do GPS systems work?

3. Should we rely on these systems 100%, how accurate are they?

4. Most cell phones now have GPS. Some people think that we should attach GPS units to children's shoes to keep track of them. The flip side of all of this GPS is that people feel like it is invading their privacy. How do you feel about someone being able to track your every single move or at least your location with the use of GPS? Do you think it invades your privacy?
