P-PS2-1
Use tools and materials to design and build a device that causes an object to move faster with a push or a pull.
Clarification statement: Emphasis should be on developing an interest in investigating forces (pushes or pulls). Examples of forces could include a string attached to an object being pulled or a ramp to increase the speed of an object.
Assessment boundary: Assessment is limited to relative measures of speed (slower, faster)
Note: this is a NYSED-specific performance expectation that is different from the Next Generation Science Standards.

NGSS Dimensions
Performance expectation P-PS2-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Planning and Carrying Out Investigations
- With guidance, plan and conduct an investigation in collaboration with peers.
- Analyzing and Interpreting Data
- Analyze data from tests of an object or tool to determine if it works as intended.
- 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.
- PS3.C: Relationship Between Energy and Forces
- (NYSED) A push or a pull may cause stationary objects to move, and a stronger push or pull in the same or opposite direction makes an object in motion speed up or slow down more quickly. (secondary to P-PS2-1)
- ETS1.A: Defining Engineering Problems
- 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.
- Cause and Effect
- Simple tests can be designed to gather evidence to support or refute student ideas about causes.
