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 ○ Interference behavior by electromagnetic radiation ○ The photoelectric effect ● identify the given reasoning to be evaluated Evaluating given evidence and reasoning Students evaluate the given ● evidence for interference behavior of electromagnetic radiation to determine how it supports the argument that electromagnetic radiation can be described by a wave model. ● phenomenon of the photoelectric effect to determine how it supports the argument that electromagnetic radiation can be described by a particle model. ● claims and reasoning for modeling electromagnetic radiation as both a wave and particle, considering the transfer of energy and information within and between systems, and why for some aspects the wave model is more useful and for other aspects the particle model is more useful to describe the transfer of energy and information.

ELA CONNECTIONS ● Assess the extent to which the reasoning and evidence in a text support the author’s claim or a recommendation for solving a scientifc or technical problem. ● Cite specifc textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account.
