In this lesson, students will investigate error. As shown in earlier activities from navigation lessons 1 through 3, without an understanding of how errors can affect your position, you cannot navigate well. Introducing accuracy and precision will develop these concepts further. Also, students will learn how computers can help in navigation. Often, the calculations needed to navigate accurately are time consuming and complex. By using the power of computers to do calculations and repetitive tasks, one can quickly see how changing parameters likes angles and distances and introducing errors will affect their overall result.

Engineers must be aware that the theoretical equations they use to describe the physical world are approximations. Some equations are accurate approximations, and others are rough. An engineer must have the experience and skill to determine how much error is acceptable for a particular design. Engineers use many techniques, many of which involve computers, to help process the many calculations required to make good estimations. Understand value computers have on society and describe the advantages as well as disadvantages of using a computer Describe the difference between accuracy and precision. Understand that mathematical concepts are required when navigating. 50TeachEngineering.orgJeff WhiteMatt LippisPenny AxelradMalinda Schaefer ZarskeJanet Yowellhttp://www.nps.gov/jeff/LewisClark2/Education/ForTeachers/PatrickGassJourney/GassLtrPg21.htmhttp://www.sailnet.com/forums/cmps_index.phphttp://www.scsc.k12.ar.us/1999outwest/members/MockK/lesson_plan.htmhttp://academic.brooklyn.cuny.edu/geology/leveson/core/linksa/treasurehunt.htmlhttp://home.earthlink.net/~nbrass1/cardart.htmS11416DDInternational_Technology_Education_Association-ITEA_STL_StandardsTechnologyF.
