The Strands Walk is a simple field trip activity designed to acquaint students with an unfamiliar area and with each other. The teacher's role in this activity is to help the students express what they observe, experience, and question. Methods of study and concepts for emphasis are included in this publication. A major portion of the booklet is devoted to the student task forms. Each task is based on one of the Strands concepts of the National Park Service's Environmental Education Program: variety and similarity; patterns; interaction and interdependence; continuity and change; and evolution and adaptation. Three additional tasks concern problem focus. In a final section to the teacher, there are behavior objectives associated with the activity and an illustration of the data-theory cycle. (MA)
