Performance Expectation. K-PS2-2. 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.

Assessment Boundary: Assessment does not include friction as a mechanism for change in speed.

Disciplinary Core Ideas. PS2.A: 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.

Crosscutting Concepts: Cause and Effect: Events have causes that generate observable patterns.

Disciplinary Core Ideas. (Engineering)

• ETS1.A: Defining and Delimiting an Engineering Problem
  Asking questions, making observations, and gathering information are helpful in thinking about problems. (secondary to K-ESS3-2)
• ETS1.B: Developing Possible Solutions
  Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problem’s solutions to other people. (secondary to K-ESS3-3)
