Knowledge

Students know:
  • Electromagnetic radiation (e.g., radio, microwaves, light) can be modeled as a wave pattern of changing electric and magnetic fields or, alternatively, as particles.
  • Electromagnetic radiation may be ionizing or non-ionizing type. Non-ionizing type of radiation is used in common electronic devices.
  • Non-ionizing type of radiation is used in common electronic devices.

Skills

Students are able to:
  • Identify types of electromagnetic radiation.
  • Select credible resources from the Internet and AVL for use in the argument.
  • Categorize electromagnetic radiation according to safety levels for humans.
  • Cite specific textual evidence to support analysis of science and technical texts.
  • Determine the central ideas or conclusions of a text; trace the explanation or depiction of a complex process, phenomenon, or concept; provide an accurate summary of the text distinct from prior knowledge or opinions.
  • Engage in argument from evidence on the safety of electromagnetic radiation.

Understanding

Students understand that:
  • Non-ionizing radiation, such as those emitted in electronics, cannot cause immediate damage, but does interact with the body to potentially cause indirect damage, following long-term exposure.
  • Ionizing radiation, such as X-rays and gamma rays, can be hazardous.
