Plate"
Activity: Portable Sundial IV
The excerpts reprinted below are from "A Customized Sundial Onepager"
by David Batch, GLPA Proceedings, 1993, pp. 25-27. Used with permission.
For this paper plate version (shown as a rough draft), the variation comes in
the making of the gnomon. Measure and draw a wedge on each of two plates,
with the angle being equal to your latitude. On the first plate, cut the
radius on the left wedge line and fold up the wedge at the right line. On
the second plate, cut the radius on the right wedge line and fold up the wedge
at the left line. Then stack the plates and secure the two wedges with
tape to create a single gnomon.
From the base of each gnomon mark off the appropriate number of degrees and
label the hours according to the instructions below.
