Engaging in Argument from Evidence

Cause and Effect

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.

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.

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.
