Petroglyph Rock Carving Replicas

on March 5, 2014

The 2nd grade made replicas of our petroglyph artifact today in class.   We choose to use wax, foam, and pumice as our material.   Each design had advantages and disadvantages.   Our foam was easy to carve, but did not seem very durable.  The wax was easy to carve and was light weight.   The pumice was difficult to carve because all the air pockets in the rock made it crumbly and less durable.  Next class we will be trying to carve limestone, alabaster, and soapstone.   We will be creating new designs of different southwest desert animals that the students will be studying this spring for the desert zoo project.

look at some of our samples below:
