Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.
Clarification statement: Examples of evaluation and refinement could include determining the success of the device at protecting an object from damage and modifying the design to improve it. Examples of a device could include a football helmet or a parachute.
Assessment boundary: Assessment is limited to qualitative evaluations and/or algebraic manipulations.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of HS-PS2-3.
This section could be expanded upon. You can help out by adding to this section.
Assessment
What assessment of HS-PS2-3 might look like on a NY state exam.

NGSS Dimensions
Performance expectation HS-PS2-3 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Constructing Explanations and Designing Solutions
- Apply scientific ideas to solve a design problem, taking into account possible unanticipated effects.
- PS2.A: Forces and Motion
- If a system interacts with objects outside itself, the total momentum of the system can change; however, any such change is balanced by changes in the momentum of objects outside the system.
- ETS1.C: Optimizing the Design Solution
- Criteria may need to be broken down into simpler ones that can be approached systematically, and decisions about the priority of certain criteria over others (trade-offs) may be needed.
- Cause and Effect
- Systems can designed to cause a desired effect.
