### Hide and seek, meters per minute of longitude

This term for GPS hide and seek I chose an open and easy spot just west of the gym. I actually picked the location using Google Earth. Google Earth has been spot on for locations, so I took the risk. The location was N 06° 54.605, E 158° 09.355'.

Malcom and Lerina were the first group to find the location, and to find me. I had moved south into a shadier location.

Only a few meters north Bernis Pernes, Edward Reyes, and Neilie Mendiola were tracking my location, they were the second group to arrive at my location. Rain then moved us east to the sheltering overhang of the gym.

Laboratory seven has settled on a formula that produces a nice linear relationship while building directly on the prior day's hide and seek activity. The laboratory puts numbers to the question of how far apart is 0.001 minutes in meters? How close to Lee Ling's hiding spot will the coordinates provided put a student group?

In the above image each student has a GPS and is standing at the exact same latitude and longitude as determined by the GPS. The group was able to start at N 06° 54.564', E 158° 09.600' and walk east on the N 06° 54.564' line of latitude. That run is right next to the classrooms, very tight to the corner of the building.

In the 11:00 class I decided to try a new line, running north on a line of longitude. To avoid the solar panels, I opted to move west to N 06° 54.505', E 158° 09.541' I would have preferred a N 06° 54.500' start, but that was not an option due to the polystachion grass. The track had a drainage hole early on and 61 meters (200 feet) occurred under the covered walkway. The track had a solid ending however out at 213 meters (700 feet).

182 meters (600 feet) was just a couple feet over onto the road. The football field appeared solid, so I requested that the class attempt to go out to 213 meters (700 feet). That proved to be possible. Another 30 meters would have put us into mud.

Both runs worked well and generated good linear relations of 1829 meters per minute and 1854 meters per minute. The second half of the laboratory was done in the A204 computer laboratory with Google Earth.
