Preparation

1. Select a suitable, safe outdoor site. Locate an object at
the site that casts a narrow shadow. The object needs to
be short enough for participants to measure its height. If
nothing is available in the outdoor area, set a broom or
yardstick in a coffee can full of gravel or sand, or pound a
sturdy stake into the ground, or set a clean plunger on the
pavement as in the illustration for Step 2.

2. Make copies of the sundial gnomon on heavy paper. The
gnomon is the part of the sundial that will stand up
on the paper plate and cast a shadow.
