- Finding North

Materials: 1 stick or flagpole, 1 piece of string.

Procedure:

- At about 11:00, mark an x at the tip of
shadow created by your stick or fixed pole (eg. flagpole).
Use this X as the starting point for your circle.Simply
tie the string to the stick which must be vertical, and pull
the string tight. Then with
chalk or another utensil mark the circumference
of the circle that you will create by keeping
the string tight and moving it in a circular
direction.

About every 10 minutes mark an additional x at the tip of the shadow. Do this until about 1 pm. By then, one of the x's should have touched the outline of your circle. This will be the X on the right

Now, use your string to draw two arcs. Start with the X that lies to your right. Using a 'radius' a little more than half the distance to the first X on the circle, make an arc that bows away from the x and intersects your circle. Repeat this procedure for the left X. The end result should look like this:

- The straight line that passes through the
two points of the archs' intersections,
points directly North/South.
