Standard PHYS.4.2 Engage in argument based on evidence that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model better explains interactions within a system than the other. Emphasize how the experimental evidence supports the claim and how models and explanations are modifed in light of new evidence. Examples could include resonance, interference, diffraction, or the photoelectric effect. (PS4.A, PS4.B)

basics of quantized energy, the photoelectric effect, and the Compton effect. This will lead them to understand light can be modeled as a particle known as a photon.

Identifying the given explanation and associated claims, evidence, and reasoning Students identify the given explanation that includes the following idea: ● Electromagnetic radiation can be described either by a wave model or a particle model, and for some situations one model is more useful than the other. Students identify the given ● claims to be evaluated as to whether the wave model or particle model is more useful. ● evidence to be evaluated, including the following phenomena
