Purpose
To find compass directions during the daytime.

    Materials
  • your shadow
Procedure
1. Outdoors on a sunny day at solar noon (when the sun is at its highest altitude and casts the shortest shadows).
2. Face your shadow. You are facing North, and directly behind you is South.
3. Hold your arms out to your sides. Your right hand points to the East, your left to the West.

Results
A Sun's shadow is used to find general compass directions.

Why?
In the Northern Hemisphere, shadows point north at solar noon (south, if you are in the Southern Hemisphere). Using shadows at solar noon, one can find the other compass directions. East is to your right, West to your left, and South behind you.
