Time Frame:
4 days within weeks 4 and 5
Unit:
Waves and Sound
Academic Standards
HS-PS4-1
Use mathematical representations to support a claim regarding relationships among the frequency,
wavelength, and speed of waves traveling in various media.
[Clarification Statement: Examples of data could include electromagnetic radiation traveling in a vacuum
and glass, sound waves traveling through air and water, and seismic waves traveling through the Earth.]
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.
[Clarification Statement: Emphasis is on how the experimental evidence supports the claim and how a
theory is generally modified in light of new evidence. Examples of a phenomenon could include
resonance, interference, diffraction, and photoelectric effect.]
HS-PS4-5
Communicate technical information about how some technological devices use the principles of wave
behavior and wave interactions with matter to transmit and capture information and energy.*
[Clarification Statement: Examples could include solar cells capturing light and converting it to
electricity; medical imaging; and communications technology.]
HS-ESS1-2
Construct an explanation of the Big Bang theory based on astronomical evidence of light spectra, motion
of distant galaxies, and composition of matter in the universe.
[Clarification Statement: Emphasis is on the astronomical evidence of the red shift of light from galaxies
as an indication that the universe is currently expanding, the cosmic microwave background as the
remnant radiation from the Big Bang, and the observed composition of ordinary matter of the universe,
primarily found in stars and interstellar gases (from the spectra of electromagnetic radiation from stars),
which matches that predicted by the Big Bang theory (3/4 hydrogen and 1/4 helium).]
Key/Major Concept/Essential Question(s)

Locate and count nodes and antinodes in standing wave patterns on a string or in a column of
air. (6.D.3.2)
