1. place a stick upright in a level portion of ground. Use a small stone to mark the tip of the shadow by the stick.
2. Measure & record the length between the stick and the pebble.
3. After 15 minutes, place a new pebble on the spot where the stick's shadow has moved to.
4. Measure & record the length between the stick and the pebble.
5. Repeat Steps 3 and 4 every 15 minutes until the length of the shadow is the same length as the first. The shadow will be in the opposite direction, but the length will be the same as when you started.
