This article describes a learning program of the Tohono O'odham or "desert people" of the Southwestern United States and Mexico. Their culture and knowledge on both sides of the border is for them a special way of life known as "himdag," where science is built into everyday life of gathering, hunting, farming, artistry, and sports taught through conversation and song. This traditional knowledge is being used in the community college classroom and compared with western scientific knowledge to enhance the teaching of science and environmental courses. Creative ways to support learning along with sharing traditional knowledge are best preserved when the people integrate them into their lives.
