Accuracy of measurement in navigation depends very much on the situation. If a sailor's target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed if off just the smallest bit. Many of the measurements made while navigating involve angles, and a small error in the angle can translate to a much larger error in position when traveling long distances. After this activity, students should be able to: Understand that navigation is based on mathematics; understand accuracy and precision;use right triangle trigonometry and angle measurements to calculate distances; understand the relationship between triangulation technology and other fields of study (i.e. mathematics)
