Performance expectationApply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.
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 is limited to qualitative evaluations and/or algebraic manipulations.
Every item written to HS-PS2-3 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.
