Students observe objects in motion and complete a KWL chart on forces and motion based on their prior knowledge. Through teacher demonstrations and guided discussion, students begin to recognize that a force is a push or pull, and that an unbalanced force is necessary for any changes in an object's motion. The document provides an overview of the lesson, which includes student engagement activities, explorations of motion and forces, and explanations of key concepts like push, pull, and the need for a force to cause changes in motion. Formative assessments are used to evaluate student understanding.
