Performance expectationEvaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model (quantum theory), and that for some situations one model is more useful than the other.
Emphasis is on how the experimental evidence supports the claim and how a theory is generally modified in light of new evidence. Examples of a phenomenon could include resonance, interference, diffraction, and photoelectric effect.
Assessment of the photoelectric effect is limited to qualitative descriptions.
Every item written to HS-PS4-3 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.
