The ability to make accurate quantitive predictions and to replicate experiments with the same result are hallmarks of the scientific revolution. In the last few decades it has come to be widely recognized that deterministic systems governed by simple equations can behave unpredictably. Examples of chaos will be shown using simple apparatus and computer simulations. Carl Wenning Rotation Ranking Tasks and Conceptual Exercises . Curtis Hieggelke , Joliet Junior College, Joliet, IL 60431.
Students have a great deal of difficulty dealing with rotational dynamics of rigid bodies.
This includes working with quantities such as center of mass, rotational inertia, torque, angular velocity and acceleration. A collection of ranking tasks and conceptual exercises have been developed and tested with students. They are designed to assist students with learning, understanding, and applying basic concepts and principles associated with rotational dynamics. Details and assessment results will be presented on these exercises. Doug A. Franklin and Mark S. Boley , Western Illinois University, Macomb, IL 61455.
