HS-PS4-4
Evaluate the validity and reliability of claims in published materials of the effects that different frequencies of electromagnetic radiation have when absorbed by matter.
Clarification statement: Emphasis is on the idea that photons associated with different frequencies of light have different energies, and the damage to living tissue from electromagnetic radiation depends on the energy of the radiation. Examples of published materials could include scientific journals, trade books, magazines, web resources, videos, and other passages that may reflect bias.
Assessment boundary: Assessment is limited to qualitative descriptions.
Note: this is a performance expectation for both HS chemistry and HS physics. The focus will vary based on which class this standard is being taught in.
