Ancient explorers did not have the electronic navigation systems we have now. instead, they used course, speed, time, and distance to determine their position in the ocean. When traveling in the ocean the course is the direction that you intend to steer the vessel. However, with the wind, current and other factors, the direction of the vessel changes. This true path is called "Course made good\". In this four-part activity, you will plot a path based on various criteria, The course is always due East (90" when measuring from 0" north clockwise). Part 1 Using the map below, chart out a course of 5 squares a month starting from Massachusetts, heading due East, Map each of these vectors using a blue pencil. It will take_ months and the vessel will land in Panz Unfortunately, the wind also plays a role in the destination. Now calculate the path with the following wind vectors. Draw the course vector in blue, then add the Wind vector in orange to the tail of the blue vector. Using vector addition, draw the resultant vector in green. Month 1 Month 2 Month 3 Month 4 Month 5 Month 6 2 squares south 3 diagonal squares southwest No wind 4 diagonal squares northeast 3 squares south 3 diagonal squares southeast It will take months and the vessel will land in Fans The wind is not the only factor. There are also ocean currents. Now calculate the path with the course vector in blue (part 1), the wind vectors in orange (part 2). and the ocean currents below in red. Using vector addition calculate the resultant vectors in green.

It would take approximately months to reach .
