K-PS2-2 Motion and Stability: Forces and Interactions
Students who demonstrate understanding can: Analyze data to determine if a design solution works as intended to change the speed or direction of an object with a push or a pull.
Clarification Statement: Examples of problems requiring a solution could include having a marble or other object move a certain distance, follow a particular path, and knock down other objects. Examples of solutions could include tools such as a ramp to increase the speed of the object and a structure that would cause an object such as a marble or ball to turn and using a rope or string to pull an object.
Assessment Boundary: Assessment does not include friction as a mechanism for change in speed.
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.	Analyzing and interpreting data: Analyzing data in K–2 builds on prior experiences and progresses to collecting, recording, and sharing observations. Analyze data from tests of an object or tool to determine if it works as intended.	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. Defining Engineering Problems: (secondary to K-PS2-2) A situation that people want to change or create can be approached as a problem to be solved through engineering. Such problems may have many acceptable solutions.
