071 Where in the world is Lee Ling?

In this "hide and seek" activity you will work in teams to learn about latitude and longitude. The learning model is based on discovery learning. Each team will have a global positioning satellite (GPS) receiver. You form your own teams based on the number of GPS units. Your task is to find Lee Ling.

Lee Ling is at: N 06° 54.605, E 158° 09.355'

Garmin eTrex directions, light version. There are five buttons on the eTrex: Scroll up through options, Scroll down through options, "Enter", Page (change screen), and Power.

• Go OUTSIDE under the open sky, not under the covered walkway!
• Press and hold the power button to power on the unit. Release after a couple of seconds. Wait. The unit will power up. Wait for the unit to "acquire satellites."
• After acquiring satellites press the Page button until you see a round circle with N, S, E, and W. This is the compass screen.
• If the compass screen does not display the latitude and longitude, press Scroll down button until you see the longitude and latitude displayed.
• Make the numbers on the GPS match N 06° 54.605, E 158° 09.355' to find me and the class location for the day.

Although the GPS receivers appear identical, some use an older operating system. With the older GPS units you will have to use the compass bearing screen and the down arrow to display the location screen. For the newer GPS units there is an additional screen after the compass bearing screen that can display the latitude and longitude. If nothing else: study the directions, play with the buttons. Discover and learn!

Remember: the unit will only work OUTSIDE.

This game has a 55 minute time limit: one class period. If you have not found Lee Ling and the class meeting location by the end of the period, then return the GPS units to the division of natural sciences and mathematics before 1:00 P.M. Thursday's laboratory is also outdoors. Good hunting!
