K-PS2-1 Motion and Stability: Forces and Interactions
Students who demonstrate understanding can: Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
Clarification Statement: Examples of pushes or pulls could include a string attached to an object being pulled, a person pushing an object, a person stopping a rolling ball, and two objects colliding and pushing on each other (e.g. ramps such as blocks or wooden moldings with cars and balls; paper towel threaded on rope or string across the classroom).
Assessment Boundary: Assessment is limited to different relative strengths or different directions, but not both at the same time. Assessment does not include non-contact pushes or pulls such as those produced by magnets.
Crosscutting Concepts	Science & Engineering Practices	Disciplinary Core Ideas
Cause and Effect: Simple tests can be designed to gather evidence to support or refute student ideas about causes.	Planning and carrying out investigations: To answer questions or test solutions to problems in K–2 builds on prior experiences and progresses to simple investigations, based on fair tests, which provide data to support explanations or design solutions. With guidance, plan and conduct an investigation in collaboration with peers.	Forces and Motion: Pushes and pulls can have different strengths and directions. Pushing or pulling on an object can change the speed or direction of its motion and can start or stop it. Types of Interactions: When objects touch or collide, they push on one another and can change motion. Relationship Between Energy and Forces: A bigger push or pull makes things speed up or slow down more quickly
