Track-it Jacket

Topic: 5E Earth, Sun and Moon

The Trailblazer jacket is a new piece of clothing, fitted with satellite navigation, to track a child's position and inform their parents of their whereabouts to within four metres, 24 hours a day. It uses a system of satellites orbiting the Earth to figure out the child's position. This information is then sent direct to the home computer. Its makers believe it will help to secure children and make parents less anxious. However, many children believe we might be taking technology too far as it makes them feel like they are being spied on.

In this activity children will use data to determine positions using the same method as sat nav equipment. They will discuss the advantages and disadvantages of this invention.
