Subject Area: Human Influence on Plant Growth and Development

Grade Level: 5th Grade

The goal of this lesson was to make a strong connection between American Indian knowledge and culture and a Science topic students often explore in 5th Grade. During our unit on Living Systems, much of my students' work focuses on the interrelationships among various environmental factors, including human influences. The development of corn from teosinte through the use of selective cultivation is an excellent example of American Indian scientific application. Extending the lesson to the planting of corn, beans, and squash together as the Three Sisters offers a great opportunity to examine interrelationships among plants and humans.
