Make Your Own Petroglyph


Projects For You
Just for Teachers

Here's what a finished petroglyph looks like.

Look at some common Indian symbols, or create your own. On a piece of paper "write" petroglyph stories using these Indian symbols or ones that the students invent.

With the help of an adult:

Mix up a batch of plaster of paris to the consistency of thick pancake batter. Scoop out a large spoonful of material and place it on a square of foil on a desk or table. It should be about about the size of a large pancake. -- 4 - 5" in diameter and 1/4 - 1/2 " thick. Let the plaster of paris rounds dry for several hours.


Paint or dip each round into very thick brown paint to cover both sides. Set in sun to dry.


Using something hard, like a large nail, carve on the smoothest side of your plaster of paris "stone". Carve part of the symbol story that you wrote earlier. Use your nail to carve through the brown paint and into the still rather soft plaster of paris .

Let it dry completely and enjoy your own petroglyph.
