Process
Finding Your Location

Your task is to find your latitude and longitude with the supplies and materials available. Remember your plane crashed on December 21, the first day of winter. The newspaper you were reading said sunrise in London was at 7:36 a.m. Your watch is still set on London time. This morning you noticed that the sun came up at 4:44 a.m., by your watch.

You will construct an astrolabe and use it to measure the latitude of Polaris, the North Star.
Using a stick and a protractor, you will also measure your latitude during the day.
Using the time of sunrise given above and the worksheet provided, you will calculate your longitude.
Using the NOVA tutorial, you will be able to correctly calculate your longitude three out of four times.
