This article describes a force and motion unit that spanned four weeks (50 minutes a day) in a fifth-grade classroom. The inquiry-based learning progression mirrors Piaget's Theory of Cognitive Development (1952) because it allowed students to manipulate materials and ideas as they actively constructed and reconstructed their knowledge of motion and stability based upon these experiences with forces and interactions. The learning progression aligned with the Next Generation Science Standards, as it enabled the students to plan, design, and test various systems as they applied their knowledge of all three laws of motion and the law of gravity. The learning progression included five parts: (1) dropping singular objects from a fixed height; (2) dropping paired objects from a fixed height; (3) pushing objects and pendulums and applying to PhET Simulations; (4) measuring the distance and speed of objects on a tape measure track; and (5) doing a coin slide activity.
