Navigation, high-tech style, was the lesson for the day in CATS 9 science clash at Calhoun High School.
After observing magnetic fields around bar magnets, students learned about the earth's magnetic field and the world-wide use of magnets for navigation since the most ancient of times.
After working with a compass and learning how to navigate across school grounds, the students learned how to use a GPS unit to find their way home.
Included, lessons on how a GPS unit works, why and when it would be used, how to use it to find a location in terms of latitude, longitude and elevation and how to use the compass to determine what direction and traveling speed.
Finally, students learned how to "mark a waypoint" and use the GPS unit to find their way back to that waypoint after a period of wandering.
