NGSS Performance Expectations
High School PE's: Star Spectra Digi Kit

    1) High School Physical Science: Waves and Electromagnetic Radiation
    HS-PS4-3
    Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.

    Evidence Statements Pertaining to this Performance Expectation

    • Evaluating Given Evidence and Reasoning 2.c Students evaluate the given 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.


      2) High School Physical Science: Waves and Electromagnetic Radiation
      HS-PS4-4
      Evaluate the validity and reliability of claims in pulished materials of the effects that different frequencies of electromagnetic radiation have when absorbed by matter.

      Evidence Statements Pertaining to this Performance Expectation

      • Evaluating Given Evidence and Reasoning 2.a.1 Students use reasoning about the data presented, including the energies of the photons involved (i.e., relative wavelengths) and the probability of ionization, to analyze the validity and reliability of each claim.
