8th Grade Science Unit 2: Waves, Sound & Light / 15-16
Reporting Topics: Properties of Mechanical and Electromagnetic Waves
Topic / Knowledge: / Assessments:
Properties of Mechanical and Electromagnetic
Waves / 4 / In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught.
3
Proficient / Students demonstrate they have developed an understanding of:
·  the relationship between energy, frequency, wavelength and amplitude
·  how waves transfer energy
2 / Students will recognize or recall:
specific vocabulary such as:
·  wavelength, frequency, amplitude, crest, trough, longitudinal, transverse, vibration, medium, compression, rarefaction, wave speed, hertz, electromagnetic waves, mechanical waves (such as sound)
basic knowledge such as:
·  waves transfer energy
·  recognize the wavelength, amplitude, crest and trough of a transverse wave
·  recognize the compressions and rarefactions of a longitudinal wave
·  recognize that wave speed is affected by the media through which they travel
Reporting Topics: Interactions of Waves
Interactions of Waves / 4 / In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught.
3
Proficient / Students demonstrate they have developed an understanding of:
·  the various wave interactions and are able to discuss examples of each (transmission, absorption, reflection, refraction, diffraction, scattering and interference)
o  how the color of an object is perceived (transmission and reflection)
·  the relationship between visible light wavelength and frequency (how color of light is determined)
·  differences among the wavelengths and frequencies of the electromagnetic spectrum
2 / Students will recognize or recall:
specific vocabulary such as:
·  transmission, absorption, reflection, refraction, interference, scattering, transparent, translucent, opaque, diffraction, electromagnetic spectrum
basic knowledge such as:
·  the difference among transparent, translucent and opaque
·  the ranges of the electromagnetic spectrum (radio waves to gamma waves)
·  the visible spectrum
