Make a Compass
Things needed:
Rub one end of the pin along the magnet about
12 times. Rub in one directions only. Do
not rub back and forth. Lift the pin up each
time.
Place the pin on the cork. Gently place the
cork in the bowl of water. At first, the
pin will swing around, then it will point
steadily in one direction. It points along
the magnetic line between the earth's north
and south poles.
What Is Cartography?
Carography is the art or technique or making maps or
charts.
Resources
Check your local library for information
on maps and compasses. If you have access
to the Internet, try using various search
engines to look for the information you need.
A field trip to a nearby museum or the local
U.S. Geological Survey office may provide
an excellent hands-on experience in your
local community.
