3-PS2-4 Motion and Stability: Forces and Interactions
Students who demonstrate understanding can: Define a simple design problem that can be solved by applying scientific ideas about magnets.*
Clarification Statement: Examples of problems could include constructing a latch to keep a door shut and creating a device to keep two moving objects from touching each other.
Assessment Boundary: N/A
Crosscutting Concepts	Science & Engineering Practices	Disciplinary Core Ideas
N/A	Asking Questions (for science) and Defining Problems (for engineering): Asking questions and defining problems in grades 3–5 builds on grades K–2 experiences and progresses to specifying qualitative relationships. Define a simple problem that can be solved through the development of a new or improved object or tool.	Types of Interactions: Electric, and magnetic forces between a pair of objects do not require that the objects be in contact. The sizes of the forces in each situation depend on the properties of the objects and their distances apart and, for forces between two magnets, on their orientation relative to each other. Interdependence of Science, Engineering, and Technology: Scientific discoveries about the natural world can often lead to new and improved technologies, which are developed through the engineering design process.
