Track-it Jacket

In this activity children use data to determine positions using the same method as satellite navigation equipment.

Description

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.

Children will use data to determine positions using the same method as satellite navagation equipment. They will discuss the advantages and disadvantages of this invention. 

Learning Objective:

-    that the Moon orbits the Earth

-    that satellites orbit the Earth

Children will learn:

-    that data from more than one satellite is needed to identify an exact location.

-    that satellites can receive and transmit data back to Earth 

-    to appreciate the advantages and disadvantages of satellite navigation for humans
