Students investigate error. As shown in earlier activities from navigation lessons 1 through 3, without an understanding of how errors can affect position, one cannot navigate well. Students explore how computers can help in navigation. By using the power of computers to do calculations and repetitive tasks, they see how changing parameters likes angles and distances and introducing errors will affect their overall result.
